    David Tartter, Deputy State’s Attorney, Montpelier, for Plaintiff-Appellee.
    Richard R. Goldsborough, South Burlington, and David Carico, El Segundo, California, for
    Defendant-Appellant.
    PRESENT: Reiber, C.J., Skoglund, Robinson, Eaton and Carroll, JJ.
    ¶ 1.   ROBINSON, J. Defendant appeals his jury conviction for sexually assaulting his
    seven-year-old daughter, A.B. On appeal, defendant raises a host of arguments challenging the
    trial court’s (1) admission of A.B.’s out-of-court statements pursuant to Vermont Rule of Evidence
    804a, (2) exclusion of certain evidence concerning A.B.’s mother’s state of mind and conduct,
    (3) ruling allowing A.B. to testify out of defendant’s presence pursuant to Vermont Rule of
    Evidence 807(f), (4) denial of discovery of some of A.B.’s mental-health records, and
    (5) admission of expert testimony that he argues improperly “vouched” for A.B.’s credibility. We
    affirm.
    ¶ 2.    This case began in December 2015 when mother reported to law enforcement that
    her daughter, A.B. (born Nov. 11, 2008), said that defendant had sexually abused her. Defendant
    and mother had been on-and-off romantic partners for a number of years, and defendant was A.B.’s
    father. After an investigation, including an interview of A.B. by a detective from the Chittenden
    Unit for Special Investigations, the State charged defendant with two counts of aggravated sexual
    assault of a victim under thirteen years pursuant to 13 V.SA. § 3253(a)(8). The evidence at trial
    included testimony by mother, defendant, expert witnesses for both sides, the detective who
    initially interviewed A.B. and defendant, and the physician who examined A.B. following the
    report, a video recording of the detective’s initial interview of A.B., and a video recording of A.B.’s
    own trial testimony. The jury convicted on both counts, and the court sentenced defendant to thirty
    to fifty years on each count, to be served concurrently.
    ¶ 3.    We consider each of defendant’s challenges on appeal, expanding on the factual
    and procedural background as relevant.
    I. A.B.’s Out-of-Court Statements
    ¶ 4.    Defendant challenges the trial court’s determination that A.B.’s videotaped out-of-
    court statements to Detective Rene Young were admissible under Vermont Rule of Evidence 804a.
    ¶ 5.    Rule 804a allows out-of-court statements by a child under twelve to be admitted
    into evidence in a proceeding where the child is the alleged victim of a sexual assault, “the
    statements were not taken in preparation for a legal proceeding,” the child is available to testify in
    court or under Rule 807, and “the time, content and circumstances of the statements provide
    substantial indicia of trustworthiness.” V.R.E. 804a(a). Defendant argues that the statements to
    Detective Young did not meet Rule 804a’s requirement that “the time, content and circumstances
    of the statements provide substantial indicia of trustworthiness.”
    ¶ 6.    The trial court made the following findings in considering the State’s motion to
    allow admission of A.B.’s out-of-court statements under Rule 804a. Defendant and A.B.’s mother
    2
    had an unhealthy relationship throughout 2015, and on December 13, 2015, they had a long
    argument while home with A.B. During the argument, defendant taunted mother with the
    accusation that mother had molested A.B., and he said he should report her to the police. In fact,
    mother did later tell the police that when A.B. was an infant, under coercion by defendant, mother
    took photographs of herself “inappropriately touching” A.B. and sent them to defendant. Mother
    testified that on the night of December 13, defendant would not leave her alone, and he kept
    arguing with her and asking her to have sex with him. She eventually called an adult-crisis hotline.
    After her call to the hotline, mother took A.B. to a grocery store to get snacks. At the grocery
    store, A.B. was not listening to mother, so mother sat her down and asked if how she was acting
    had anything to do with the fight. A.B. said no. Mother said A.B. seemed nervous—she was
    fidgeting, kicking her legs, and playing with her belly button. Mother asked A.B. if defendant had
    hurt her. A.B. said he had grabbed her arm, but did not say defendant had done anything else.
    Mother had asked A.B. in the past if defendant had hurt her, but A.B. had always said he hadn’t.
    ¶ 7.    Mother then asked if defendant had ever told A.B. not to tell about something
    because she could be taken away. A.B. froze. Mother told A.B. a couple times that if anything
    had happened, she needed to know so she could keep A.B. safe. A.B. then whispered into her ear
    “we had sex.” Mother testified that she was shocked. She asked A.B. if she knew what sex was,
    and what a penis was, and A.B. said yes to each. Mother was shocked to hear that too. She asked
    A.B. where defendant had touched her, and A.B. spread her legs and pointed to her genitals.
    Mother asked how many times it had happened, and A.B. said it happened once over the summer.
    Mother asked twice if A.B. was sure, and A.B. finally said it might have happened a couple of
    times. Mother then called the police.
    ¶ 8.    A.B. was placed in the custody of the Department for Children and Families (DCF)
    on an emergency basis. The next day, Detective Young conducted a forensic interview with A.B.
    The interview was videotaped. At the beginning of the interview, Detective Young asked A.B.
    3
    questions to establish that A.B. could tell the difference between truth and lies, and had A.B.
    promise to tell the truth. Eventually, A.B. told Detective Young that defendant put his “gina” in
    her “gina,” and gave details as to how it happened. When Detective Young asked what “gina”
    meant, A.B. pointed to her genitals, and said it was used for sex and “to go potty.” She also said
    that defendant had put his “gina” in her “gina” on a second occasion, this one at night, but did not
    provide further details.
    ¶ 9.    The State moved to allow admission of both A.B.’s statements to mother and to
    Detective Young; defendant opposed the admission of both. The court held that A.B.’s statements
    to mother were not admissible because their circumstances—including that defendant had
    threatened to report mother to the police for sexually assaulting A.B. shortly before A.B. made the
    statements—did not provide substantial indicia of trustworthiness, as Rule 804a(a)(4) requires. It
    noted, however, that this ruling reflected only that the State had not met its burden of establishing
    that the circumstances provided sufficient indicia of trustworthiness, and was not a decision as to
    the veracity of the statements. The court did allow admission of A.B.’s statements to Detective
    Young, as it found their time, content, and circumstances bore substantial indicia of
    trustworthiness.
    ¶ 10.   In connection with the latter conclusion, the court credited the testimony of the
    State’s expert, Dr. Halikias, concerning the protocols for such interviews. The court found that
    A.B. “appeared consistent about the disclosures throughout the interview,” and appeared reluctant
    and hesitant. The court found that she “looked uncomfortable and at times frightened,” and her
    whispered disclosure to Detective Young was “convincing.” The court concluded that “despite
    some flaws in the detective’s questioning style, the flaws did not affect the validity or reliability
    of the interview” because A.B. “did not appear manipulated by the flawed questions and resisted
    leading and repeated questioning.”
    4
    ¶ 11.   On appeal, defendant argues that the trial court erred in finding the circumstances
    of A.B.’s statements to Detective Young trustworthy. He argues that mother coerced A.B. into
    making the statements the night before, and that A.B.’s statements to the detective were
    contaminated by that coercion. Defendant preserved this issue for appeal.
    ¶ 12.   The trial court’s decision to admit A.B.’s statements under Rule 804a was a
    discretionary one, which we review deferentially and would reverse only upon finding abuse of
    discretion. State v. Felix, 
    2014 VT 68
    , ¶ 19, 
    197 Vt. 230
    , 
    103 A.3d 927
    . The determination of
    trustworthiness under Rule 804a(a)(4) is a factual finding, which this Court will not overturn unless
    clearly erroneous. State v. Gallagher, 
    150 Vt. 341
    , 348, 
    554 A.2d 221
    , 225 (1988).
    ¶ 13.   In determining whether the circumstances of a child’s statement have the indicia of
    trustworthiness required for admission under Rule 804a(a)(4), a court “may consider such factors
    as: the circumstances of the initial disclosure, including the setting and person to whom the
    disclosures were made; internal consistency and detail of disclosures; timing and conduct of
    interviews, including whether nonleading questions were asked; freshness and spontaneity of
    disclosures; appropriate body language; risk of fabrication” and “evidence of coercion or
    manipulation” as well as “accuracy of peripheral detail; the child’s affect, intelligence, memory,
    and concern for the truth; and corroboration by medical and other evidence.” State v. Pratt, 
    2015 VT 89
    , ¶ 7, 
    200 Vt. 64
    , 
    128 A.3d 883
    .
    ¶ 14.   We conclude that the trial court’s finding that A.B.’s statements to Detective Young
    bore sufficient indicia of trustworthiness was not clearly erroneous. Evidence supporting this
    conclusion includes the State’s expert’s testimony that conduct of the interview was reasonably
    sound, despite some violations of the accepted interview protocol; A.B.’s word choice and body
    language, which the trial court could reasonably find supported her credibility; A.B.’s apparent
    resistance to leading questions when asked; and the fact that A.B., then a seven-year-old child,
    made reasonably consistent and at times graphic disclosures. See State v. LaBounty, 
    168 Vt. 129
    ,
    5
    138, 
    716 A.2d 1
    , 7-8 (1998) (holding that young children’s graphic accounts of sexual abuse to
    caseworkers and police officers, made the day after their initial disclosures to their mothers,
    supported finding that statements were trustworthy). Accordingly, we find no abuse of discretion
    in the trial court’s decision to admit A.B.’s statements to Detective Young under Rule 804a.
    ¶ 15.   We understand defendant’s view that none of these indicia of trustworthiness is
    sufficient to surmount the contamination arising from mother’s coercion of A.B. the night before,
    but conclude that the trial court’s exclusion of A.B.’s out-of-court statements to mother does not
    undermine its admission of the statements to Detective Young. The trial court emphasized that its
    decision to exclude A.B.’s out-of-court statements to mother rested on the State’s failure to meet
    its burden of showing that the time and circumstances of A.B.’s disclosure to mother provided
    substantial indicia of trustworthiness. The court noted that the content of the actual disclosure to
    mother, and the child’s behavior and reluctance to disclose, as reported by mother, were factors
    that provided some support for the trustworthiness of the statements. However, in light of the
    unhealthy relationship between mother and defendant and defendant’s threats to report mother for
    sexual abuse shortly before A.B.’s disclosure to mother, the court concluded the State had not met
    its burden. The trial court did not find that mother coerced A.B.’s initial reports the night before,
    and the evidence, while it may support such an inference, does not compel such an inference.
    Accordingly, the court’s conclusion that the statements to Detective Young were trustworthy,
    which implicitly rejected the claim that the statements were irretrievably contaminated by mother’s
    questioning of A.B. the night before, was not clearly erroneous.1
    1
    Defendant also suggests that A.B.’s statements to Detective Young in the investigative
    interview may also have been the result of prior suggestion or coercion by Detective Young,
    pointing to an exchange at the beginning of the investigative interview when Detective Young said
    “I met you last night; we talked a whole bunch” and A.B. replied, “Because you made me.” The
    evidence supporting defendant’s suggestion that Detective Young contaminated A.B.’s testimony
    through their conversations the night before is sparse at best. The only evidence is that Detective
    Young made small talk with A.B. about matters other than the allegations at issue. The trial court’s
    failure to infer on the basis of this evidence that Detective Young contaminated A.B.’s reports and
    6
    II. Evidence of Mother’s Mental Illness and Alleged Assault
    ¶ 16.   Defendant argues that the exclusion of certain evidence of mother’s “mental illness
    and her aggravated assault” on A.B. deprived him of his constitutional rights to confrontation and
    to present a defense under the Fifth, Sixth, and Fourteenth Amendments of the U.S. Constitution
    and Chapter I, Article 10 of the Vermont Constitution.
    ¶ 17.   The background relevant to this claim is as follows. In broad terms, defendant’s
    theory of the case, beyond his general denial, is that mother coached A.B. to make the allegations
    because she thought defendant was going to report her for sexually abusing A.B. and she sought
    to preempt and divert attention from that report. In particular, around 2009, when A.B. was an
    infant, mother took photos of herself touching A.B.’s vagina with her fingers and mouth. (Mother
    has subsequently alleged that defendant forced her to take these pictures and send them to him.)
    This happened while mother was enrolled in a residential parenting program. When her counselor
    at the program asked her about the photos mother had taken, mother lied to her counselor, claiming
    that they were of her breastfeeding. On the day in December 2015 when A.B. later made her
    disclosure, defendant called mother a child molester in the context of a fight. After the fight,
    mother called a mental-health crisis line. She then took A.B. to the store, where mother said A.B.
    made her disclosure to mother. Mother reported A.B.’s allegations against defendant shortly
    thereafter. At that time, she also disclosed her own prior (2009) sexual assault of A.B. to the
    police. Subsequently, while this case was pending, during a supervised visit with A.B. mother told
    A.B. about the 2009 assault and said to A.B. that defendant had made her (mother) do it. Although
    mother denied to the DCF caseworker that she made any such disclosure, the caseworker observed
    that A.B. provided a high level of detail about the disclosure. Finally, mother has a history of
    undermined the trustworthiness of A.B.’s recorded statements to Detective Young was not clearly
    erroneous.
    7
    significant mental-health issues. Defendant argues that these events show mother’s motive to
    coach A.B. to make a false report against him and also undermine mother’s credibility generally.
    ¶ 18.   In connection with these matters, the parties made a series of motions pretrial,
    which we discuss more fully as they are relevant to particular rulings.
    ¶ 19.   At trial, the court admitted considerable evidence relating to mother’s mental
    health, but stated that defendant could not introduce evidence of mother’s “mental health status as
    such” because it was not relevant. The court allowed defendant to introduce evidence suggesting
    that mother had mental-health concerns, including that mother had in the past seen a mental-health
    professional, had attempted suicide, and had called a mental-health crisis line the night A.B.
    disclosed defendant’s sexual abuse of her. It also allowed evidence that mother and defendant had
    in the past argued about mother’s mental health and her refusal to seek therapy.
    ¶ 20.   Likewise, the trial court ultimately allowed defendant to introduce evidence
    relating to mother’s alleged assault of A.B. and some of her subsequent statements about it.2 On
    the stand, mother admitted that she had taken pictures of herself inserting her finger into A.B.’s
    vagina when A.B. was an infant. She conceded that was why defendant called her a child molester,
    and that she told the police about it on the evening that she called to report defendant’s abuse of
    A.B. because she “thought it would be best to get it out” herself “rather than have [defendant]
    report it.” The court also admitted A.B.’s testimony that mother had told A.B. that when A.B.
    “was a little baby or girl . . . my dad made my mom stick her finger in my private.” The court also
    allowed defendant to ask mother on the stand if she had told A.B. this.
    2
    Mother initially asserted her Fifth Amendment right against self-incrimination, but the
    court concluded that she waived that right through her answers to questions on cross-examination.
    8
    ¶ 21.    On appeal, defendant challenges six specific rulings or clusters of rulings that he
    argues denied him the opportunity to fully present his defense.3
    ¶ 22.    “We review the trial court’s evidentiary rulings deferentially and reverse only when
    there has been an abuse of discretion that resulted in prejudice.” Felix, 
    2014 VT 68
    , ¶ 19 (quotation
    omitted). We will find an abuse of discretion only upon a showing that “the court’s discretion was
    either withheld or exercised on clearly unreasonable grounds.” State v. Cartee, 
    161 Vt. 73
    , 76,
    
    632 A.2d 1108
    , 1110 (1993). Recognizing the constitutional issues at play when a criminal
    defendant is prevented from introducing evidence to impeach an opposing witness or call into
    question a witness’s motive, our “analysis of whether the trial court abused its discretion . . . is
    further amplified by defendant’s constitutional right to confront witnesses against him.” 
    Id. With these
    standards in mind, we consider each of defendant’s respective challenges on appeal.
    A. Testimony from Detective Young Regarding Mother’s Admission
    ¶ 23.    Defendant argues that the trial court erroneously declined to allow him to call
    Detective Young to testify that mother admitted to Detective Young on the night of A.B.’s initial
    disclosure of abuse that she, mother, had previously sexually abused A.B.
    ¶ 24.    The ruling at issue followed a discussion at the bench on the second day of trial.
    Defendant was seeking to highlight mother’s statements to A.B. about the prior assault, and
    mother’s denial to the DCF caseworker that she made those statements. Defense counsel asked
    3
    Because defendant’s briefs described various categories of evidence defendant claimed
    were erroneously excluded, but did not identify with clarity or citations to the record the specific
    rulings challenged on appeal, at oral argument the Court requested that defendant provide a list of
    the specific rulings he challenges on appeal. In identifying the rulings at issue on appeal, we rely
    on defendant’s response. Some other challenges raised in defendant’s briefs but not identified in
    his post-argument list of specific rulings challenged relate to claimed rulings that apparently never
    existed. For example, defendant argues in his brief that he wanted to introduce evidence that
    mother was facing charges for aggravated assault when she testified against defendant, and that
    she was not offered a plea deal until after testifying against him, which would have been evidence
    of her motive to testify against him and would have impeached her credibility. Defendant never
    sought to introduce such evidence before the trial court. He cannot now claim that he should have
    been allowed to introduce evidence that he did not seek to introduce. V.R.E. 103(a)(2).
    9
    whether he could call Detective Young to say that at the interview, mother said that she had
    touched A.B.’s vagina, and then call A.B.’s foster mother to testify that A.B. had reported that
    mother had disclosed this prior abuse during a visit. The court noted that A.B. had already testified
    to these events and concluded that defendant did not need to bring in Detective Young to repeat
    that.
    ¶ 25.   The trial court has considerable discretion to refuse to allow cumulative evidence.
    Pcolar v. Casella Waste Sys., Inc., 
    2012 VT 58
    , ¶ 9, 
    192 Vt. 343
    , 
    59 A.3d 702
    , as amended on
    denial of reh’g (Aug. 28, 2012).
    ¶ 26.   Here, even if the court abused its considerable discretion in denying defendant the
    opportunity to elicit from Detective Young testimony about matters that were already in the record,
    defendant was not prejudiced by the ruling since mother herself subsequently testified that at the
    time she reported A.B.’s disclosures, she told Detective Young that she, mother, had committed
    the prior acts. This is essentially the same testimony defendant sought to elicit from Detective
    Young. The fact that mother made this disclosure to Detective Young was clear to the jury and
    undisputed. Accordingly, defendant suffered no prejudice from the court’s exclusion of the
    additional testimony, and any error was harmless. See V.R.Cr.P. 52(a) (“Any error, defect,
    irregularity or variance which does not affect substantial rights shall be disregarded.”); State v.
    Haskins, 
    2016 VT 79
    , ¶¶ 17, 28, 
    202 Vt. 461
    , 
    150 A.3d 202
    (holding error is harmless if it is
    beyond reasonable doubt that jury would have convicted even had error not occurred, given
    strength of case without excluded evidence, and strength of excluded evidence, taking into account
    whether it was cumulative or duplicative).
    B. Testimony from Detective Young Regarding Mother’s Inconsistent Statement
    ¶ 27.   Defendant challenges the trial court’s exclusion of a prior inconsistent statement
    mother made to Detective Young. The background is as follows. During mother’s testimony,
    after mother described the photos she took of herself abusing A.B. when A.B. was an infant,
    10
    defendant elicited mother’s confirmation that she had made a report about the incident when she
    was at the residential program where it happened. In connection with that report, defense counsel
    asked mother, “Isn’t it true that . . . you told [your counselor] that you had not taken the pictures
    that you just described?” Mother responded, “I had told her that I thought I did, but wasn’t sure,
    and she said that if—if I actually did it, she thinks I would have remembered.” Defendant also
    elicited testimony from mother that DCF interviewed her following this report and did not
    substantiate her for abuse. Mother admitted that DCF’s report indicated that mother said she only
    took pictures of herself lying down without a top and A.B. sitting in a diaper on her stomach, but
    said she did not remember saying that to DCF. On appeal, defendant argues that the trial court
    improperly excluded evidence of mother’s statement to Detective Young that she had previously
    told her counselor at the residential program that she sexually abused A.B.
    ¶ 28.   Although defendant identifies this argument in his post-argument list of rulings at
    issue on appeal, nowhere in his appeal briefs does he provide a record citation to the court’s
    contested ruling on this point so we can review it.4 See V.R.A.P. 28(a)(4)(A) (appellant’s brief
    must contain “the issues presented, how they were preserved, and appellant’s contentions and the
    reasons for them—with citations to the authorities, statutes, and parts of the record on which the
    appellant relies”).
    ¶ 29.   Nor does he point us to his request to call Detective Young for this purpose and his
    proffer as to what Detective Young was expected to say. See V.R.E. 103(a) (“Error may not be
    predicated upon a ruling which admits or excludes evidence unless a substantial right of the party
    is affected, and . . . [where] the ruling is one excluding evidence, the substance of the evidence
    was made known to the court by offer or was apparent from the context within which questions
    4
    Defendant provides a transcript of an audiotaped interview of mother by Detective Young
    in which mother claims to have accurately described the photos to the counselor many years prior,
    but this citation does not tell us where, if anywhere, the trial record reflects an attempt by defendant
    to elicit this evidence in the trial.
    11
    were asked.”). Defendant did not attempt to question Detective Young about the purported
    inconsistent statement by mother when Detective Young testified during the State’s case in chief,
    nor when she testified in the State’s rebuttal case. Defendant has not pointed us to an instance
    when he sought to call Detective Young in his own case for the purpose of asking this question.
    Because defendant has not identified a request, proffer, and ruling for us to review, we cannot
    conclude that the trial court committed error.5
    C. Testimony of Counselor
    ¶ 30.   In connection with the same issue, defendant sought to call the counselor from the
    program mother was enrolled in to testify that mother had told the counselor back in 2010 that the
    pictures mother had taken and sent to defendant were essentially benign, and that mother did not
    disclose the sexually abusive nature of the pictures to the counselor. In declining defendant’s
    request, the court explained that mother had already admitted to committing the 2009 acts, and the
    proffered testimony showing that mother lied about them to her counselor in 2010 would add little.
    ¶ 31.   While constitutional concerns do limit the trial court’s discretion to exclude
    evidence impeaching the credibility or exposing the bias of a witness such as mother, the court’s
    ruling denying defendant’s request to call the counselor for this purpose was well within its
    discretion. The Confrontation Clause limits trial courts’ discretion to restrict impeachment of a
    key prosecution witness’s credibility. 
    Cartee, 161 Vt. at 76
    , 632 A.2d at 1111. This is because
    the purpose of confrontation is to give the opponent the chance “to test the truth and accuracy of a
    witness’ testimony” and expose “a witness’ motivation in testifying.”

    5
    If the record contained a ruling precluding defendant from calling Detective Young to
    testify that mother told Detective Young that mother had previously accurately described to her
    counselor the photos she took of A.B. in 2009, the court’s ruling would not have been an abuse of
    discretion for the same reasons the court’s ruling excluding testimony by the counselor herself was
    not an abuse of discretion. See infra, ¶¶ 30-33.

    expose a witness’s bias would render cross-examination “largely an empty gesture.” 
    Id. at 77,
    632 A.2d at 1111. Moreover, jurors are “ ‘entitled to have the benefit of the defense theory before
    them so that they [can] make an informed judgment as to the weight to place on the witness’
    testimony.’ ” 
    Id. at 76,
    632 A.2d at 1110 (alterations omitted) (quoting Davis v. Alaska, 
    415 U.S. 308
    , 317 (1974)).
    ¶ 32.   In this case, though, the jury heard the core evidence to support defendant’s theory
    that mother sexually abused A.B. when A.B. was an infant; that defendant argued with mother and
    called her a child molester shortly before mother reported A.B.’s disclosures; and that mother then
    reported A.B.’s disclosures to the police, along with mother’s own actions six years prior, in an
    effort to preempt any report defendant might make about mother’s conduct and shift the attention
    to him.
    ¶ 33.   Evidence that mother did not fully disclose the contents of the pictures when she
    spoke to her counselor about them in 2010 would have, at most, impeached mother’s credibility
    by exposing somewhat inconsistent statements on a collateral matter—that is, the scope of her
    2010 disclosures to her counselor about the photos she took. A court has broad discretion to
    exclude extrinsic evidence introduced to impeach a witness on a collateral matter. See V.R.E.
    608(b) (providing that extrinsic evidence may not be used to prove instances of witness’s conduct
    for purposes of attacking or supporting witness’s credibility, other than conviction of crime as
    provided in Rule 609); State v. Congress, 
    2014 VT 129
    , ¶¶ 46-48, 
    198 Vt. 241
    , 
    114 A.3d 1128
    (upholding trial court’s refusal to allow extrinsic evidence to impeach witness on collateral
    matters: whether witness truly needed glasses to read document in court, and whether witness truly
    lacked education to do so). Mother’s actions toward A.B. in 2009 may not be collateral to the
    issues in this case given defendant’s theory that they explain mother’s bias and motives to coach
    a false allegation against defendant. Mother’s candor to her counselor five years before the events
    at issue in this case, on the other hand, lacks “even a tenuous connection to [her] testimony about
    13
    what she observed in connection with the events at issue in this case.” Congress, 
    2014 VT 129
    ,
    ¶ 48. The court acted within its discretion in excluding this evidence.
    D. Testimony of DCF Social Worker
    ¶ 34.     Defendant challenges the trial court’s ruling precluding him from calling the DCF
    social worker to testify that (1) mother denied speaking with A.B. about her sexual abuse of A.B.
    as an infant and (2) the social worker observed that A.B. provided a high level of detail regarding
    the charges against mother.
    ¶ 35.     As with his challenge concerning testimony from Detective Young that he contends
    was improperly excluded, defendant does not provide a record citation to a specific proffer of
    evidence and court ruling excluding the evidence he describes in this challenge on appeal, so our
    ability to review the argument is limited. See V.R.A.P. 28(a)(4)(A). Instead, defendant’s brief
    cites to a lengthy bench conference among counsel and the court regarding defendant’s desire to
    call mother as a witness in order to elicit mother’s testimony that she did not disclose her past 2009
    sexual abuse to A.B. The focus of the discussion was whether such questioning would implicate
    mother’s Fifth Amendment rights, and whether mother had waived her right against self-
    incrimination.
    ¶ 36.     Defendant’s express purpose at trial for seeking to elicit the testimony from mother
    was to impeach A.B. That is, defendant was not trying to undermine mother’s credibility by
    showing that mother denied disclosing the 2009 abuse to A.B. when, in fact, she did. Instead, he
    sought to show that mother did not disclose the 2009 abuse to A.B., thereby calling into question
    A.B.’s credibility as a reporter of sexual abuse. In the context of this back-and-forth between the
    parties and court concerning mother’s Fifth Amendment rights, defense counsel raised the
    possibility of calling a social worker to testify that mother had denied disclosing the 2009 abuse
    to A.B. The court first suggested that would be hearsay, but then after further discussion concluded
    that it might not be hearsay if used to impeach mother by showing she had said different things to
    14
    different people. The court did not make any ruling at all regarding the admissibility of potential
    testimony by the social worker on this point. In fact, when defense counsel indicated that he might
    need to lay more foundation from the social worker “who will say that A.B. said these things,” the
    court replied, “Okay. Then fine.” Thereafter, the discussion turned back to mother’s Fifth
    Amendment rights and went from there. Nowhere in the discussion cited by defendant in his brief
    on appeal did the court rule that defendant could not call the DCF social worker to testify that (1)
    mother denied speaking with A.B. about her sexual abuse of A.B. as an infant and (2) the social
    worker observed that A.B. provided a high level of detail regarding the charges against mother.
    ¶ 37.   Not only has defendant failed to cite to a specific trial-court ruling excluding the
    evidence he now argues was wrongly excluded on appeal, but when defendant sought to call the
    DCF social worker, his proffer as to her expected testimony did not include either of the two items
    that he now relies upon as the basis for his appeal.6 Because defendant has not directed us to any
    actual ruling excluding the testimony he now says was wrongly excluded, and has not pointed us
    to any proffer in the trial court, we cannot review his claim of error on appeal. See V.R.E.
    103(a)(2).7
    E. Evidence Concerning DCF’s 2010 Assessment of Defendant
    ¶ 38.   Twice defendant sought to present evidence that in 2010 DCF viewed defendant as
    a stable and supportive factor in the family. First, defendant indicated an intent to offer into
    evidence a DCF report reflecting that in 2010 DCF viewed defendant as the more stable parent in
    6
    The proffer instead related to DCF’s 2010 assessment of defendant, mother, and their
    family. See infra, ¶¶ 38-39.
    7
    We note that if defendant did proffer that the social worker would testify that mother
    denied telling A.B. about the 2009 sexual abuse, the trial court would have acted within its
    discretion in excluding the testimony. Given that mother herself testified that she did not tell A.B.
    about the 2009 abuse, the court could have concluded that testimony from a third party reporting
    that mother made the same denial to the third party would be cumulative. Pcolar, 
    2012 VT 58
    ,
    ¶ 9.
    15
    the family.8 The court questioned the relevance of the report, particularly given its remoteness.
    Second, when defendant sought to call the DCF social worker referenced above, counsel proffered
    that he expected the social worker to testify that back in 2010 DCF viewed defendant as a stable
    and supportive factor in the family. The trial court concluded that the evidence was not relevant
    to any of the issues in the case and was not proper character testimony.
    ¶ 39.     The trial court did not abuse its discretion in excluding evidence regarding DCF’s
    assessment of defendant’s role in the family five years prior to the charges in this case—when
    A.B. was a very young child. The court could reasonably conclude that the proffered evidence did
    not tend to make the existence of any fact of consequence to determining defendant’s guilt any
    more    or     less   probable.     See    V.R.E.    401    (defining    “relevant    evidence”    as
    “evidence having any tendency to make the existence of any fact that is of consequence to the
    determination of the action more probable or less probable”); In re Letourneau, 
    168 Vt. 539
    , 554,
    
    726 A.2d 31
    , 41 (1998) (“[T]he trial court has broad discretion to exclude marginally relevant
    evidence that is remote, tends to confuse the issues or causes a waste of time.”).9
    8
    In his brief in chief, defendant asserts that the court did not allow defendant to call the
    DCF caseworker who wrote this report. In his reply brief, defendant indicated that he did not seek
    to call that caseworker as a witness but only sought to introduce her report. It is not clear how
    defendant intended to introduce the caseworker’s report if he did not call her as a witness, and
    defendant has not pointed to any place in the record reflecting that during the trial defendant
    offered the report into evidence or sought to call its author as a witness. In any event, our analysis
    does not turn on whether the excluded evidence would have come in through oral testimony or a
    written report, and does not turn on which witness defendant relied on to introduce the report.
    9
    In his brief on appeal, defendant also contends that the trial court precluded him from
    presenting evidence that mother was deemed a potential danger to A.B. because of her mental-
    health issues. He does not provide a record citation to any such proffer or ruling, but the claimed
    evidence appears to be linked to the same 2010 DCF report that described defendant as a positive
    factor in the family. To the extent that defendant proffered evidence falling into this second
    category—DCF deemed mother a danger to A.B. because of her mental-health issues—and the
    court ruled on such proffers, we likewise conclude that the trial court did not abuse its discretion
    in excluding evidence of DCF’s assessment of mother’s parenting skills in or around 2010.
    16
    F. Discovery and Testimony About Dr. Gilligan’s Evaluation of Mother
    ¶ 40.     Defendant contests the limits the court put on the disclosure to defendant of a
    psychosexual evaluation of mother conducted in connection with the criminal prosecution of
    mother for the 2009 act of sexual abuse described above, and on the testimony of its author.
    ¶ 41.     In connection with criminal charges against mother for her role in the 2009 sexual
    abuse of A.B., Dr. Claire Gilligan conducted a forensic evaluation of mother, which was provided
    to the State in connection with mother’s separate criminal case. Defendant requested an order
    requiring the State to disclose the evaluation to him, and the State objected, filing a copy of the
    evaluation with the court under seal. The court ruled that the forensic evaluation was not protected
    by any patient privilege, but concluded that much of the evaluation contained private and personal
    information not relevant to defendant’s case. The court disclosed limited portions of the evaluation
    that it concluded might be relevant to defendant’s case. The court indicated that it would consider
    further disclosures upon receiving defendant’s written motion outlining why further portions of
    the evaluation might be relevant.
    ¶ 42.     Before trial, the State filed a motion in limine requesting the exclusion of testimony
    about mother’s mental health. The State argued that there was no evidence about the state of
    mother’s mental health at the time of A.B.’s disclosure and mother’s report, there was no evidence
    that mother was suffering from any mental-health condition that would affect her ability to
    perceive and recall events, and mother’s mental health had no bearing on the existence of any fact
    of consequence.
    ¶ 43.     Defendant opposed the motion and said he wanted to introduce evidence from Dr.
    Gilligan’s report. Defendant asked the court to revisit its previous ruling releasing only a redacted
    copy of the report to him, and argued that mother’s mental state more broadly was relevant to the
    dynamic of mother’s relationship with him and the allegations in this case. The trial court
    expressed doubt, explaining that evidence of mother’s conduct may be relevant, but evidence about
    17
    her mental health and what inferences might be drawn from that is “really, really . . . far afield.”
    The court said, “I’m not saying it could not be relevant. I’m just saying I think you’re out at the
    outer fringes.” It added, “I am doubtful about whether we’re going to get into mother’s mental
    health history in connection with that. But we’ll see.” The court indicated that it would review
    the psychosexual evaluation and reserved judgment on the motion until trial.
    ¶ 44.    Immediately prior to trial, defendant subpoenaed Dr. Gilligan to testify. Dr.
    Gilligan responded with a request to quash the subpoena on the ground that she did not have ample
    notice and was not able to reschedule previously scheduled interviews and evaluations without
    considerable difficulty and consequences.
    ¶ 45.    At the beginning of trial, the court expressed generally that the issue before it was
    whether or not defendant committed the alleged acts. It indicated that evidence relating to mother’s
    motives or arguments between the parents was fair game, but evidence about mother’s “mental
    health status as such” was not relevant. The court reaffirmed its prior decision giving defendant
    only partial access to the psychosexual evaluation10 and generally deferred specific rulings
    regarding the admissibility of specific testimony until the court heard the testimony.
    ¶ 46.    After the court had taken some testimony, it took up the question of Dr. Gilligan’s
    subpoena. The court was inclined to tell Dr. Gilligan that she need not respond to the subpoena.
    Defendant emphasized that Dr. Gilligan’s testimony was significant because mother told her
    something that she did not tell anybody else: that she (mother) told the police about her 2009 sexual
    abuse of A.B. on the night she disclosed A.B.’s report about defendant because mother thought
    the report about her own sexual abuse of A.B. would sound better coming from her than from
    defendant. The court did not question the relevance of this testimony, but directed defendant to
    first cross-examine mother, on the theory that if mother testified to that effect, then testimony on
    10
    The judge who issued the pretrial discovery ruling was not the judge who presided over
    the trial.
    18
    that point from Dr. Gilligan would be cumulative. Accordingly, at the end of the State’s case,
    defendant indicated that Dr. Gilligan might not be needed, depending on mother’s testimony.
    ¶ 47.   As mother testified, defendant repeatedly refreshed mother’s recollection with a
    copy of Dr. Gilligan’s redacted report. As a consequence, mother ultimately testified herself that
    she reported her own 2009 sexual abuse of A.B. to the police in connection with her report of
    A.B.’s allegations concerning defendant because she thought it would be better coming from her
    than defendant and she was worried about defendant making a report that night about her sexually
    abusing A.B. At the end of mother’s testimony, defense counsel agreed that the court could tell
    Dr. Gilligan that she did not have to testify, saying, “I think we covered any relevance out of Dr.
    Gilligan.”
    ¶ 48.   Reviewing defendant’s challenges, we conclude that the trial court acted within its
    discretion in limiting defendant’s access to the report of Dr. Gilligan’s psychosexual evaluation of
    mother to those portions not redacted by the court. To the extent that the court precluded Dr.
    Gilligan from testifying about mother’s mental health, it acted within its discretion.
    ¶ 49.   When a defendant seeks a witness’s mental-health records which are in the State’s
    custody, and the State objects to their disclosure, the defendant is entitled to have the court review
    the requested documents. The trial court has discretion to determine whether the records “contain
    information critical to the defendant’s ability to impeach the witness” and would “therefore
    warrant disclosure. If the court concludes that, in its judgment, the records contain no information
    that should be disclosed, then the material may remain under seal and be made available for
    inspection on appellate review [by the reviewing court].” State v. Barbera, 
    2005 VT 13
    , ¶ 12, 
    178 Vt. 498
    , 
    872 A.2d 309
    (mem.) (citations and quotation omitted). The court has discretion to decide
    which, if any, portions of the records should be disclosed, State v. Rehkop, 
    2006 VT 72
    , ¶ 26 n.2,
    
    180 Vt. 228
    , 
    908 A.2d 488
    , but this “discretion is not unbounded.” Pennsylvania v. Ritchie, 480
    
    19 U.S. 39
    , 60 (1987). The court is “obligated to release information material to the fairness of the
    trial.” 
    Id. ¶ 50.
      After reviewing the sealed psychosexual evaluation with these considerations in
    mind, we conclude that the trial court’s discovery order was within its discretion. The disclosed
    portion of the report includes all of the report’s discussion concerning the circumstances
    surrounding A.B.’s disclosure, including a description of mother’s fight with defendant that
    evening, mother’s fears that he would use the 2009 incident to take A.B. away from her, and the
    manner in which A.B. made the disclosure. It includes a description of the 2009 incident and
    mother’s 2010 reports to the program in which she was enrolled and to DCF in connection with
    their questioning about the photos. It also includes discussion of mother’s alleged disclosure about
    the 2009 incident to A.B. during a supervised visit following her report to the police about
    defendant, and mother’s claim to A.B. that defendant made her do it; and reports from A.B.’s foster
    mother regarding A.B.’s disclosures to the foster mother concerning abusive acts by defendant and
    A.B.’s reflection that her mother had done a “bad thing” to her. These are the essential pieces
    relating to defendant’s theory of the case. By contrast, the redacted content that was not produced
    to defendant includes a detailed psychosocial history of mother, psychological testing, and the
    evaluator’s summary of other documents that are directly available to defendant (such as Detective
    Young’s affidavit concerning her initial interview with mother). Given the legal framework set
    forth above, these redactions were well within the trial court’s discretion.
    ¶ 51.   With respect to defendant’s challenge to the exclusion of evidence, we find no clear
    ruling actually limiting Dr. Gilligan’s testimony except a broad discussion by the court of the
    relevance of mother’s mental health in general, as contrasted with her conduct. The court’s ruling
    on this subject was in response to a general motion in limine filed by the State, and did not purport
    to address a specific proffer by defendant. The court deferred its actual rulings as to admissibility
    of evidence until it had heard the relevant testimony. Defendant never proffered testimony from
    20
    Dr. Gilligan concerning some specific aspect of mother’s mental health, so it is difficult to review
    defendant’s claim that the court precluded him from presenting testimony from Dr. Gilligan about
    mother’s mental health.
    ¶ 52.   To the extent that defendant construed the trial court’s general discussion of the
    relevance of mother’s mental health as such as a ruling, and refrained from seeking Dr. Gilligan’s
    testimony concerning mother’s mental health on that basis, the trial court acted within its
    discretion. The court left open a wide range of evidence concerning mother’s conduct, including
    conduct that reflected on or stemmed from mental-health issues. Defendant did not make a specific
    proffer of evidence relating to mother’s mental health as such that was relevant to mother’s
    capacity to tell the truth, predisposition to coaching A.B. to make false accusations, or other
    matters at issue in this case.    Based on defendant’s own proffer, Dr. Gilligan’s testimony
    concerning mother’s mental health related to mother’s mental health in 2009, at the time mother
    engaged in the sexually abusive conduct. The court could reasonably conclude that mother’s
    mental state in 2009, six years before the disclosure by A.B. and report by mother that set this case
    in motion, was too remote in time to be relevant to this case, and would unduly confuse the issues.
    See 
    Letourneau, 168 Vt. at 554
    , 726 A.2d at 41.
    ¶ 53.   Although we have relied primarily on the Vermont Rules of Evidence in the above
    analysis of defendant’s various evidentiary challenges on appeal, we emphasize that our reasoning
    in each case applies to defendant’s constitutional due process claims as well. The U.S. Supreme
    Court has recognized that the exclusion of critical evidence denies a defendant a fair trial in accord
    with the mandates of due process. Chambers v. Mississippi, 
    410 U.S. 284
    (1973). Chambers held
    that prohibiting a defendant from cross-examining a witness who had previously confessed to the
    murder the defendant was charged with, and prohibiting the defendant from offering the testimony
    of three people who had heard the witness confess to the murder, prevented him from introducing
    evidence “critical to [his] defense” and deprived him of due process. 
    Id. at 302-303.
    Unlike in
    21
    Chambers, defendant was not precluded from introducing any critical evidence. Where a trial
    court acts within its discretion to exclude evidence, there is no due process violation. See State v.
    Lamb, 
    142 Vt. 87
    , 89, 
    453 A.2d 78
    , 79 (1982) (holding that where defendant did not explain how
    evidence was admissible, argument that its exclusion violated his right to due process was
    meritless). The trial court here acted within its discretion, and there is no due process violation.11
    III. Ruling Allowing A.B. to Testify out of Defendant’s Presence Under Rule 807(f)
    ¶ 54.   Defendant raises four distinct objections to the trial court’s order allowing A.B. to
    testify outside of his presence and the implementation of that order. The generally relevant
    background is as follows. Before trial, the State filed a motion pursuant to Vermont Rule of
    Evidence 807 to permit A.B. to provide her trial testimony by two-way closed-circuit television or
    videotape outside of the courtroom.
    ¶ 55.   Following a hearing, the court granted the motion. Relying on the testimony of
    A.B.’s therapist of many months, the court found that A.B. had been diagnosed with post-traumatic
    stress disorder. The bases for the diagnosis included A.B.’s flashbacks and intrusive thoughts
    about the alleged abuse, difficulty sleeping, irritability without provocation, frequent outbursts of
    crying, and anger and frustration—symptoms that persisted at the time of the hearing. The court
    found that A.B. has a strong reaction to discussion of the events underlying these criminal charges
    and has difficulty talking about the allegations even with her own therapist.12 A.B.’s reaction to
    discussing these events has included “curling up in a ball, shutting down and not talking.” The
    court credited the therapist’s opinion that requiring A.B. to testify in a courtroom setting “creates
    11
    Likewise, defendant does not make out a claim under the Vermont Constitution. State
    v. Brillon, 
    2010 VT 25
    , ¶ 6, 
    187 Vt. 444
    , 
    995 A.2d 557
    . “Merely citing the Vermont Constitution,
    without providing any analysis of how the state constitutional provision compares with its federal
    analog, does not adequately present the issue for our review, especially where the argument was
    not presented in the trial court.” 
    Id. 12 The
    court noted that there was a brief period during which A.B. spoke excessively freely
    and openly about the events, but that that period had passed.
    22
    a substantial risk of trauma to A.B. which would substantially impair her ability to testify” and a
    substantial risk that she would be unable to respond to questions.
    ¶ 56.   In addition, in light of A.B.’s high degree of trauma caused by defendant’s alleged
    actions, together with her fear and anger toward defendant and the significant period of time not
    seeing him, the court also concluded that requiring A.B. to hear and see defendant “would present
    a substantial risk of trauma to A.B. and would substantially impair her ability to testify.” The court
    credited the therapist’s testimony and found that “it is highly likely that A.B. would completely
    shut down and respond in a very strong emotional manner.” The court accordingly ordered that
    defendant be situated in a manner that A.B. could not see or hear him during her testimony.
    ¶ 57.   On appeal, defendant argues that Rule 807(f), the provision that allows for child
    testimony outside of the sight and hearing of a defendant in limited circumstances, is facially
    unconstitutional. He further argues that the trial court abused its discretion in granting the motion,
    both because the court should not have allowed A.B.’s therapist to testify and because defendant
    was wrongly precluded from visitation with A.B., which led to the estrangement that supported
    the trial court’s assessment. Finally, he argues that the way the order was implemented prevented
    him from having contemporaneous contact with his counsel during counsel’s questioning of A.B.
    We will consider each of these challenges in turn.
    A. Constitutionality of Rule 807(f)
    ¶ 58.   Defendant argues that Rule 807(f) is facially unconstitutional because it allows
    infringement upon the right to confrontation without the constitutionally required showing of
    necessity. In particular, he emphasizes that Rule 807(f) allows a child witness in a sexual-assault
    case to testify without hearing or seeing the defendant if hearing or seeing the defendant would
    pose “a substantial risk of trauma to the child . . . which would substantially impair the ability of
    the child . . . to testify.” Defendant argues that standard allows for an exception to a defendant’s
    23
    confrontation rights without a showing that seeing or hearing the defendant would cause the child
    significant trauma, as required by Maryland v. Craig, 
    497 U.S. 836
    (1990).
    ¶ 59.    The State counters that the required finding that a child faces a “substantial risk of
    trauma” is essentially the same as a finding that the child is likely to suffer trauma, and argues that
    Craig does not require a finding of significant trauma—it simply requires that the trauma be more
    than minimal.
    ¶ 60.    Because defendant failed to raise this claim before the trial court, we review it for
    plain error. V.R.Cr.P. 52(b) (“Plain errors or defects affecting substantial rights may be noticed
    although they were not brought to the attention of the court.”); State v. Oscarson, 
    2004 VT 4
    , ¶ 27,
    
    176 Vt. 176
    , 
    845 A.2d 337
    (explaining that plain error is limited to “exceptional circumstances
    where a failure to recognize error would result in a miscarriage of justice, or where there is glaring
    error so grave and serious that it strikes at the very heart of the defendant’s constitutional rights”
    (quotation omitted)).
    ¶ 61.    In evaluating Rule 807(f), “we employ tools similar to those we use in statutory
    construction. That is to say that when construing a rule, we consider its plain language and the
    purpose it was designed to serve.” State v. Amidon, 
    2008 VT 122
    , ¶ 16, 
    185 Vt. 1
    , 
    967 A.2d 1126
    .
    Because this court rule was adopted pursuant to an act of the Legislature, we must be mindful of

    (“We afford statutes a presumption of constitutionality.”).
    ¶ 62.   Exceptions to the Sixth Amendment right to confrontation are few and narrow. The
    exception for a child witness in a prosecution for sexual assault on that child applies only upon a
    showing that testifying in the defendant’s presence would cause emotional trauma that is not mere
    nervousness or excitement or reluctance to testify but, rather, would impair the child’s ability to
    communicate. Rule 807 does purport to allow for an exception to the right of confrontation upon
    a lesser showing, in violation of the Sixth Amendment. However, because the trial court in this
    case made a finding satisfying the more rigorous constitutional standard, we conclude that
    defendant has not shown plain error.
    ¶ 63.   The Confrontation Clause, which applies to the states through the Fourteenth
    Amendment, provides that in “criminal prosecutions, the accused shall enjoy the right . . . to be
    confronted with the witnesses against him.” U.S. Const. amend. VI. The Supreme Court has long
    understood face-to-face confrontation with adverse witnesses to be central to the integrity of a
    criminal trial, in part because of the long-standing belief that it is harder to lie about someone to
    their face than behind their back. Coy v. Iowa, 
    487 U.S. 1012
    , 1019 (1988).
    ¶ 64.   The Confrontation Clause does not, however, provide “defendants the absolute
    right to a face-to-face meeting with witnesses against them at trial”; it rather “reflects a preference
    for face-to-face confrontation at trial.” 
    Craig, 497 U.S. at 844
    , 849. This is, however, a strong
    preference, and a “defendant’s right to confront accusatory witnesses may be satisfied absent a
    physical, face-to-face confrontation at trial only where denial of such confrontation is necessary
    to further an important public policy and only where the reliability of the testimony is otherwise
    assured.”13 
    Id. at 850
    (emphasis added).

    To the extent that defendant raised a claim for the first time at oral argument that A.B.’s
    testimony was insufficiently reliable because A.B. did not know she was testifying in a legal
    25
    ¶ 65.   The Supreme Court has held that a state’s “interest in protecting child witnesses
    from the trauma of testifying in a child abuse case” is a sufficiently important public policy to
    justify an incursion on the right to face-to-face confrontation, “[g]iven the State’s traditional and
    transcendent interest in protecting the welfare of children, and buttressed by the growing body of
    academic literature documenting the psychological trauma suffered by child abuse victims who
    must testify in court.” 
    Id. at 850
    , 855 (quotation omitted). However, the State must make “an
    adequate showing of necessity” in each individual case to justify allowing a child to testify outside
    the defendant’s presence; otherwise such testimony would violate the Confrontation Clause. 
    Id. at 855.
    ¶ 66.   To make this showing of necessity, the State must show that the “witness would be
    traumatized, not by the courtroom generally, but by the presence of the defendant.” 
    Id. at 856.
    It
    must also show that the witness would suffer a level of emotional trauma that “is more
    than . . . mere nervousness or excitement or some reluctance to testify” and “would impair the
    child’s ability to communicate.” 
    Id. at 856-57
    (quotation omitted). The U.S. Supreme Court has
    not decided the minimum level of trauma required, but did hold that a state statute requiring “that
    the child witness will suffer ‘serious emotional distress such that the child cannot reasonably
    communicate,’ clearly suffices to meet constitutional standards.” 
    Id. at 856
    (citing Md. Code Ann.,
    Crim. Proc. § 11-303(b)(1)).14
    ¶ 67.   Rule 807(f) on its face does not require a showing that meets this constitutional
    standard. It purports to allow a child witness to testify outside of a defendant’s presence upon a
    showing of “a substantial risk of trauma to the child” that would “substantially impair the ability

    nature, that are insufficiently raised and inadequately briefed. Brillon,

    26
    of the child . . . to testify.” (Emphasis added.) Craig held that the “trial court must find that the
    child witness would be traumatized” by the defendant’s presence and that “the trauma would
    impair the child’s ability to 
    communicate.” 497 U.S. at 856-57
    (emphases added). We understand
    the requirement that the court find that the child “would be” traumatized to require proof of not
    only a “risk” of trauma, or a “substantial risk” of trauma, but that it is more likely than not—in
    other words, that there is a preponderance of the evidence—that the child will be traumatized. See
    In re Watford, 
    809 S.E.2d 651
    , 656 (Va. 2018) (holding “use of the word ‘would’ focuses the
    inquiry . . . on the likely” outcome (quotation omitted)). Rule 807(f) does not appear to require a
    preponderance of the evidence; it requires a finding that testifying face-to-face to the defendant
    pose “a substantial risk of trauma to the child . . . which would substantially impair the ability of
    the child . . . to testify.” (Emphasis added.) Requiring a finding of “substantial risk” suggests a
    standard more analogous to probable cause or reasonable suspicion than a “preponderance.” 15 See
    15
    At least one court has concluded that the U.S. Constitution, as construed in Craig,
    requires proof by a more onerous “clear and convincing” standard. See State ex rel. Montgomery
    v. Padilla, 
    371 P.3d 642
    , 645-46 (Ariz. Ct. App. 2016) (“Given the constitutional significance of
    limiting a defendant’s right to confront witnesses face-to-face and a . . . defendant’s right to
    personally cross-examine those witnesses, . . . the heightened standard of clear and convincing
    evidence must apply.”); see also Commonwealth v. Bergstrom, 
    524 N.E.2d 366
    , 376 (Mass. 1988)
    (holding that under the Massachusetts Constitution, “in the absence of a waiver, the
    Commonwealth must show, by more than a mere preponderance of evidence, a compelling need
    for use of such a procedure. Such a compelling need could be shown where, by proof beyond a
    reasonable doubt, the recording of the testimony of a child witness outside the courtroom (but in
    the presence of the defendant) is shown to be necessary so as to avoid severe and long lasting
    emotional trauma to the child.”).
    Other courts have explicitly or implicitly endorsed a preponderance standard. See, e.g.,
    Brady v. State, 
    575 N.E.2d 981
    , 984-86 (Ind. 1991) (holding Indiana statute that allowed child to
    testify outside of court upon finding it was more likely than not that trauma would result from
    testifying in defendant’s presence met requirements of Craig); Taylor v. Wall, 
    821 A.2d 685
    , 690
    (R.I. 2003) (holding that court’s finding that child “would suffer unreasonable and unnecessary
    mental and emotional harm if required to testify in defendant’s presence” satisfied Craig
    requirements).
    Some states expressly include a preponderance standard in their statutes. See Ga. Code
    Ann. § 17-8-55(d); Mass. Gen. Laws Ann. ch. 278, § 16D(b)(1). Other states require that the
    prosecution prove that testifying in the defendant’s presence would traumatize the child by clear
    27
    State v. Perley, 
    2015 VT 102
    , ¶ 19, 
    200 Vt. 84
    , 
    129 A.3d 93
    (explaining that “probable cause” is
    a lower standard than “preponderance” of the evidence); State v. Simoneau, 
    2003 VT 83
    , ¶ 14, 
    176 Vt. 15
    , 
    833 A.2d 1280
    (explaining that reasonable suspicion to support a traffic stop must be “more
    than an unparticularized suspicion or hunch of criminal activity, but needs considerably less than
    proof of wrongdoing by a preponderance of the evidence”).
    ¶ 68.   The requirements of Rule 807(f) are clearly less stringent than Craig’s requirement
    of a finding that the child would be traumatized, and that the trauma would impair the child’s
    ability to communicate. 
    Craig, 497 U.S. at 856-57
    .16 For that reason, we agree with the
    and convincing evidence. See Ark. Code Ann. § 16-43-1001(a)(1); Cal. Penal Code § 1347(b)(2);
    Conn. Gen. Stat. § 54-86g(a); Idaho Code Ann. § 9-180(5)(1); Kan. Sess. Laws 22-3434(b); Mont.
    Code Ann. § 46-16-229(1); Nev. Rev. Stat. Ann. § 50.580(1)(a); N.Y. Crim. Proc. Law
    §§ 65.10(1), 65.20(2); Okla. Stat. Ann. tit. 12, § 2611.7(A); W. Va. Code Ann. § 62-6B-3(b).
    We conclude that, although the Legislature is free to amend the rule to require proof by
    clear and convincing evidence that testifying in a defendant’s presence will traumatize a child
    witness, the U.S. Supreme Court’s decision in Craig does not require such a heightened standard.
    We reach this conclusion for two reasons. First, had the Court intended to require a standard other
    than a preponderance, it would have so specified. Cf. Jones v. Jones, 
    905 N.W.2d 475
    , 480 n.4
    (Mich. Ct. App. 2017) (noting that when statute does not provide evidentiary burden, “default
    preponderance of the evidence standard” applies). Second, the Maryland statute the Court upheld
    in Craig did not require proof of trauma to the child by clear and convincing evidence. See 
    Craig, 497 U.S. at 840
    n.1 (quoting Maryland statute that allowed testimony by closed-circuit television
    if “[t]he judge determines that testimony by the child victim in the courtroom will result in the
    child suffering serious emotional distress such that the child cannot reasonably communicate”).
    Accordingly, we conclude that the minimum standard required by the U.S. Constitution is proof
    by a preponderance of the evidence. But see Knauff v. Hooks, No. 1:15-CV-338, 
    2016 WL 2587965
    , at *7 (S.D. Ohio May 4, 2016) (upholding statute allowing a child victim to testify
    outside the defendant’s presence if there is a “substantial likelihood that the child victim will suffer
    serious emotional trauma” from testifying in the defendant’s presence); State v. Foster, 
    957 P.2d 712
    , 727 (Wash. 1998) (en banc) (upholding statute allowing child witness to testify outside
    defendant’s presence upon finding of “ ‘substantial evidence that requiring the child to testify in
    the presence of the defendant will cause the child to suffer serious emotional or mental distress
    that will prevent the child from reasonably communicating’ ” (quoting Wash. Rev. Code
    § 9A.44.150(1)(c)). We do not address the requirements of the Vermont Constitution on this point.
    16
    We note that the standard reflected in Rule 807(f) dates back to the Legislature’s 1985,
    pre-Craig enactment. 1985, No. 82, § 1. Although the Legislature subsequently amended the rule
    post-Craig, the primary purpose of that amendment was to expand the class of victim witnesses
    subject to the rule. 1993, No. 100, § 12. We presume that the Legislature intends for this rule to
    be applied in conformity with the U.S. Constitution, Vt. Educ. Bldgs. Fin. Agency v. Mann, 127
    28
    defendant’s argument that Rule 807(f) on its face could unconstitutionally allow for an exception
    to a defendant’s confrontation rights without a sufficient showing. See United States v. Bordeaux,
    
    400 F.3d 548
    , 553 (8th Cir. 2005) (noting that 18 U.S.C. § 3509, allowing child witness to testify
    by two-way closed-circuit television upon finding child unable to testify in open court due to fear,
    is “unconstitutional to the extent that it requires a different showing of fear from what Craig
    requires”).
    ¶ 69.   However, we do not reverse on that basis because notwithstanding the lower
    standard reflected in Rule 807(f), the trial court made a constitutionally sufficient finding to
    support its ruling under Rule 807(f). In particular, after making findings about the trauma A.B.
    experienced in connection with the events giving rise to this prosecution, and her reaction to
    attempts to discuss the topic, the court found that it was “highly likely that A.B. would completely
    shut down and respond in a very strong emotional manner.”17 Although this finding doesn’t match
    the approved language in Craig word for word, we conclude that the court found a high
    likelihood—not just a substantial risk—that A.B. would be traumatized and that the trauma would
    impair her ability to testify. Accordingly, we cannot conclude that the constitutional infirmity in
    Rule 807(f) seriously affected defendant’s substantial rights. Oscarson, 
    2004 VT 4
    , ¶ 27 (“To
    reverse on plain error, we must find not only that the error seriously affected substantial rights, but
    also that it had an unfair prejudicial impact on the jury’s deliberations.”).
    Vt. 262, 271, 
    247 A.2d 68
    , 74 (1968), and refer the matter to the Advisory Committee on the Rules
    of Evidence to propose amendments to conform the rule to the requirements of the U.S.
    Constitution.
    17
    We recognize that the court made other findings to the less rigorous “substantial risk”
    standard called for in Rule 807(f), but conclude that in light of the court’s other specific factual
    findings, the “highly likely” finding encompasses all the essential elements required by Craig.
    29
    B. Reliance on Testimony of Child’s Therapist
    ¶ 70.   Defendant’s second challenge to the court’s ruling under Rule 807(f) is that the
    court improperly relied on testimony from A.B.’s therapist in making the necessary findings. He
    contends that the provider-patient relationship between the therapist and A.B. renders the therapist
    biased given the therapeutic alliance between provider and patient. He points to the prohibition in
    Rule 5 of the Vermont Rules of Family Procedure against appointing an expert who presently or
    formerly provided treatment to the person being evaluated, and professional ethical requirements
    prohibiting counselors from providing forensic evaluation services concerning current or past
    clients. He concedes he did not object to the therapist’s testimony before the trial court.
    ¶ 71.   Because defendant did not raise this argument before the trial court, we review the
    court’s admission of this testimony for plain error. V.R.Cr.P. 52(b); Oscarson, 
    2004 VT 4
    , ¶ 27.
    ¶ 72.   Defendant’s argument fails to recognize the distinction between a forensic
    evaluator and a treating provider. The child’s therapist in this case was not retained by the court
    to conduct an impartial assessment. She did not hold herself out to the court as a forensic evaluator.
    She testified as A.B.’s treating clinician, and her testimony was expressly informed by that
    therapeutic relationship.
    ¶ 73.   A treating provider who satisfies the requirements of Vermont Rule of Evidence
    702 may be a competent expert witness. That rule provides:
    If scientific, technical, or other specialized knowledge will assist
    the trier of fact to understand the evidence or to determine a fact in
    issue, a witness qualified as an expert by knowledge, skill,
    experience, training, or education, may testify thereto in the form of
    an opinion or otherwise, if (1) the testimony is based upon sufficient
    facts or data, (2) the testimony is the product of reliable principles
    and methods, and (3) the witness has applied the principles and
    methods reliably to the facts of the case.
    V.R.E. 702. Although he questions the propriety of the therapist testifying given her therapeutic
    relationship with A.B., defendant does not (and did not) contest her actual qualifications to testify
    30
    about the matters at issue, and does not contend that the testimony is not based upon sufficient
    facts or methodology.
    ¶ 74.   This is not to say that testimony in court from a treating provider is not potentially
    fraught. Commentators have emphasized the distinction between the duties of a therapist versus a
    forensic or neutral evaluator, and have highlighted the issues that may arise when an individual’s
    treating therapist testifies as an expert in court. See, e.g., 1 Demothenes Lorandos & Terence
    Campbell, Cross Examining Experts in the Behavioral Sciences § 2.3 (Nov. 2018 update)
    (contrasting treating provider’s focus on therapeutic alliance with patient with expert witness’s
    obligation to testify objectively and candidly); Kirk Heilbrun, Child Custody Evaluation: Critically
    Assessing Mental Health Experts and Psychological Tests, 29 Fam. L. Q. 63, 69-71 (1995)
    (identifying problems that arise when treating mental-health provider testifies in litigation).
    ¶ 75.   But these issues are not disqualifying if a treating provider otherwise has sufficient
    training and bases for opinions to meet the requirements of Rule 702. This Court has routinely
    upheld trial courts’ reliance on expert testimony by a treating provider. See, e.g., State v. J.S., 
    174 Vt. 619
    , 621, 
    817 A.2d 53
    , 56 (2002) (mem.) (relying on testimony of appellant’s treating
    psychiatrist to support trial court’s determination); In re K.M., 
    165 Vt. 569
    , 570, 
    678 A.2d 1263
    ,
    1264 (1996) (mem.) (relying in part on testimony of involuntarily hospitalized appellant’s treating
    physician concerning appellant’s competence).
    ¶ 76.   A proper response to the tensions between a treating provider’s roles as treater and
    testifying expert is cross examination or impeaching evidence highlighting potential issues with
    the treating provider’s testimony. See, e.g., 1 Lorandos & Campbell, supra, § 2:21 (laying out
    model cross examination of treating provider); Mary Stumo, Holly M. Robbins & Julie M.
    Giddings, Litigating the Sexual Harassment Case § 20.III (1st ed. 2010) (noting that treating
    psychiatrists or psychologists may be vulnerable to attack by the defense).
    31
    ¶ 77.    While the therapist’s relationship with A.B. would have been a fair basis for cross
    examination, defendant has identified no law suggesting that simply because she was A.B.’s
    treating provider she could not provide expert testimony based on her training and her experience
    treating A.B. Cf. State v. Dunbar, 
    152 Vt. 399
    , 410-11, 
    566 A.2d 970
    , 976-77 (1989) (holding
    fact that clinician who testified only about general principles concerning child victims of sexual
    assault was child victim’s treating provider did not, by itself, suggest bias).18 Given these
    considerations, we conclude that the court’s admission of the therapist’s testimony was not plain
    error.
    C. Limits on Defendant’s Contact with A.B.
    ¶ 78.    Defendant next argues that he was denied substantive due process because he did
    not have pretrial visits with A.B., even though mother had supervised visitation with her, and that
    fact led to the court’s decision to allow A.B. to testify by prerecorded video pursuant to Rule
    807(f). Defendant did not raise these claims below, so we review them for plain error. V.R.Cr.P.
    52(b); Oscarson, 
    2004 VT 4
    , ¶ 27.
    ¶ 79.    In reviewing defendant’s argument, it is difficult to discern which ruling, of which
    court, defendant asks us to review. Defendant does not directly challenge the trial court’s order
    pursuant to Rule 807 that relies in part on the lengthy period of estrangement between defendant
    and A.B. in authorizing A.B.’s testimony outside of defendant’s presence. Nor does he appear to
    challenge any order of the trial court relating to defendant’s contact with A.B. In short, defendant
    presents us no actual order in this case to review.19
    18
    Defendant’s reliance on Vermont Rule of Family Procedure 5 is misplaced. Not only is
    that rule inapplicable to proceedings in the criminal division, but the rule, on its face, precludes a
    current or former treating provider from conducting an evaluation for the court only when the
    subject of the evaluation does not consent. V.R.F.P. 5(b).
    19
    Nor do we find an order in this docket prohibiting contact between defendant and A.B.
    32
    ¶ 80.   Instead, he asks us to take “judicial notice” of “discussions regarding visitation” in
    a proceeding in the Family Division. Apparently, he is not actually challenging a court order in
    the Family Division, but contends that “discussions” in that court support his claim. His reasoning
    is that DCF generally opposed visitation unless defendant met a number of conditions, and that the
    State is therefore accountable for the lack of contact between him and A.B., and for the subsequent
    impact of that estrangement on his right to be visible to her while she testified in the criminal
    proceeding.
    ¶ 81.   Defendant has not raised a cognizable argument on appeal. To the extent that
    defendant took issue with DCF recommendations to the court in the Family Division, he was free
    to present contrary evidence in that setting. To the extent that he objected to a ruling of the Family
    Division regarding contact or visitation, he was free to appeal that ruling. To the extent he objected
    to the impact of a ruling of the Family Division on the proceedings in this criminal case, he could
    have sought an order from the trial court mitigating that impact. He did none of these things.
    Because defendant has not presented any legal challenges to any orders of the Superior Court,
    Criminal Division, in this proceeding, he has not given us anything to review. See V.R.A.P.
    28(a)(4) (explaining requirements for adequate briefing); King v. Gorczky, 
    2003 VT 34
    , ¶ 21 n.5,
    
    175 Vt. 220
    , 
    825 A.2d 16
    (declining to address constitutional challenges because briefing was
    inadequate). We cannot, on that basis, find plain error.20
    D. Communication with Attorney During 807(f) Testimony
    ¶ 82.   Defendant contends that because he was unable to communicate with his attorney
    during A.B.’s videotaped testimony, the proceeding violated his Sixth Amendment rights to
    20
    After oral argument, defendant moved for this Court to take judicial notice of “the
    discussions regarding visitation” in a transcript of a disposition hearing in A.B.’s Family Division
    proceeding. Because the proper forum for appealing a court order in the Family Division is an
    appeal of that order from the Family Division, not an appeal of a criminal conviction of one of the
    parties to the Family Division proceeding, we deny defendant’s motion.
    33
    counsel and to confrontation. Defendant represents that he sat in a separate room and heard the
    audio of A.B.’s Rule 807 testimony by cell phone. He further represents that his cell phone was
    placed on mute so that he could not be heard. He contends that the arrangement deprived him of
    contemporaneous communication with his attorney, who was present in the room with A.B.
    ¶ 83.   Defendant did not make any claim at the trial-court level about his inability to
    contemporaneously communicate with his attorney during A.B.’s testimony, let alone that it
    deprived him of constitutional rights. In fact, the video of the testimony shows that defendant’s
    counsel was actively involved in the set-up for the testimony, in the presence of a judge.
    ¶ 84.   We need not decide whether defendant has waived his objection,21 because even
    assuming plain-error review applies, defendant has not shown plain error. V.R.Cr.P. 52(b);
    Oscarson, 
    2004 VT 4
    , ¶ 27. The only evidence defendant offers of prejudice is that at one point,
    the cell phone stopped working. At that moment, the State’s attorney asked A.B. about an
    “incident with high heels.” Defendant claims on appeal that he did not hear A.B.’s reply that “I
    do not want to remember the high heel thing,” and that had he heard it, “he could have asked his
    counsel to followup.” He offers no indication that he had particular information about this
    testimony to inform counsel’s follow-up or that counsel would have in fact followed up on his
    suggestion, and he does not explain what kind of follow-up to this question would have been
    helpful. His argument is too speculative to support plain error.

    , 67-68, 
    732 A.2d 722
    , 726 (1999) (defendant could not argue he was denied
    right to confront witness when he agreed to procedure that allowed admission of pretrial deposition
    without live testimony of witness). But see State v. Grace, 
    2016 VT 113
    , ¶¶ 15-19, 
    204 Vt. 68
    ,
    
    165 A.3d 122
    (holding, where “there [wa]s nothing to indicate that counsel consulted with
    defendant on this point and explained his rights and what he would be sacrificing by not appearing,
    or that defendant in response knowingly and voluntarily waived the right,” defendant had not
    knowingly waived right to confrontation, and applying plain-error review).

    IV. A.B.’s Counseling Records
    ¶ 85.   Defendant argues that A.B.’s counseling records should have been discoverable
    because, when the State requested that A.B. be allowed to testify pursuant to Rule 807, her mental
    health became an element of a claim or defense under Vermont Rule of Evidence 503(d)(3), and
    thus the records were no longer privileged. However, he has not identified any order by the trial
    court which he claims was erroneous.
    ¶ 86.   At the hearing on the State’s motion to allow A.B. to testify pursuant to Rule 807,
    the State subpoenaed A.B.’s therapist to testify as to the trauma that testifying in defendant’s
    presence would cause A.B. Counsel for the Howard Center, where the therapist was employed,
    informed the court that the Howard Center had “obtained a very narrow release from DCF,” which
    it represented was A.B.’s legal custodian at the time, to discuss only those portions of her mental-
    health records that “related to the substance” of the inquiry under Rule 807. The Howard Center
    said it intended to object to any questioning about A.B.’s mental-health records that went outside
    the scope of the release and that could be understood to waive A.B.’s patient privilege more
    broadly. Defendant objected, arguing that A.B.’s entire counseling record should “be open”
    because all of the therapist’s contacts with A.B. informed the determination of the likelihood of
    trauma to A.B. The court responded, “I think we can navigate it. If not—if I’m at a point where
    I don’t feel comfortable issuing certain rulings to objections or offers, then I will recess, and we’ll
    take a look at some law. But let’s attempt to proceed.” Defendant does not point to any indication
    in the record that he subsequently made an objection or sought release of additional records in light
    of testimony elicited, and he does not cite any subsequent court rulings on the matter.
    ¶ 87.   In the absence of an actual ruling by the trial court, we have nothing to review. This
    case is akin to State v. Hooper, 
    151 Vt. 42
    , 
    557 A.2d 880
    (1988). In that case, the defendant argued
    he should have been allowed to introduce evidence of a Federal Bureau of Investigation analysis
    35
    of the hair found on the victim. We concluded that the claim was not properly before us. We
    explained:
    Defendant’s evidence about the analysis of the hair samples was not
    covered by the motion in limine and, therefore, was not excluded by
    the grant of that motion. Defendant made no attempt to raise his
    theory about the hair samples during his trial. Even though, at the
    motion hearing, the trial court expressed its doubt that the evidence
    regarding the hair samples would be admissible, it did not rule that
    it was inadmissible. . . . Since defendant never availed himself of
    the opportunity to present evidence to prove his argument during
    trial, this Court has nothing before it to review.
    
    Id. at 45-46,
    557 A.2d at 882. Because defendant did not make specific requests for appropriate
    discovery based on the testimony as it came out in the proceeding, the court never got the chance
    to actually rule on the matter in the context of specific evidence, and defendant has nothing to
    appeal.22
    V. Expert Testimony and Vouching
    ¶ 88.   Finally, defendant argues that the trial court abused its discretion in allowing
    testimony by the State’s experts, Dr. William Halikias and Dr. Joseph Hagan, that impermissibly
    vouched for A.B.’s credibility. Defendant did not raise these claims at the trial level, so we
    review for plain error.
    ¶ 89.   At trial, the State offered expert testimony by Dr. Halikias concerning current
    research on children’s resistance to coercive questioning. The State offered Dr. Halikias’s
    testimony in rebuttal to expert testimony put on by the defense concerning research showing that
    repeated questioning, leading questions, and nonverbal cues can reduce the reliability of children’s
    testimony and even alter their memories of events. When asked about research about children’s
    ability to resist coercive questioning, Dr. Halikias noted that some studies have found that
    22
    Defendant explains his failure to follow up on this issue by stating that any request for
    the records after the hearing would not have been helpful. He fails to acknowledge that he had the
    opportunity during the hearing to point to specific testimony and argue that it opened the door to
    further discovery before the conclusion of the hearing.
    36
    “remarkably few [children] affirm” a false, leading question. He testified about a study of
    preschoolers subjected to repeated interviews in which adults asked “coercive questions, such as
    he took your clothes off, didn’t he? We know that happened. We spoke to your mother. Your
    mother told us about it. The older children told us about it. Now you tell us about it.” He noted
    that “in that particular research study, ninety-one percent of the children resisted even that coercive
    line of questioning.” Summing up the research in this field, he said “it’s never all” children who
    resist coercive questioning. He concluded that “it’s certainly possible” to induce a child to falsely
    say an adult took off their clothes, “but it’s difficult, and it becomes more difficult” to induce a
    child to falsely recount “genital touch because young children don’t know what sex is.” He said
    it is particularly hard to lead a child to falsely acknowledge or develop a false memory of genital
    touch by someone the child is close to. He then went on to describe a study wherein researchers
    induced college students to falsely believe they had committed a felony when they were fifteen by
    repeatedly interviewing them and giving them false information. He concluded, “it’s possible” to
    induce a false memory “even with adults. But it takes a lot of work, and it takes effort.”
    ¶ 90.   The State also introduced expert testimony by Dr. Hagan as to the results of the
    sexual-assault examination he performed on A.B. after her forensic interview. Dr. Hagan testified
    that the examination findings were normal. He also testified that while he sometimes takes a
    patient history, he did not take one for A.B. because sexual abuse is traumatic, and A.B. had just
    been through a forensic interview in which she “made significant disclosures” that were “very
    clear and graphic.” After reviewing those disclosures, Dr. Hagan and the nurse with whom he
    was working decided that eliciting further history from A.B. was unnecessary, particularly because
    of the concern that it would further traumatize her.
    ¶ 91.   On appeal, defendant argues that Dr. Halikias vouched for A.B.’s credibility when
    he testified that fewer than nine percent of children in a study were induced to falsely identify
    genital touch. He also contends Dr. Hagan implied that A.B. had been sexually abused, thereby
    37
    vouching for her allegations against defendant, when he described her disclosures as significant,
    clear, and graphic.
    ¶ 92.   Because defendant did not timely raise either of these claims at the trial level, we
    review for plain error. V.R.Cr.P. 52(b). To preserve a claim that evidence was improperly
    admitted, a party must make “a timely objection or motion to strike.” V.R.E. 103(a)(1). “This
    means that the objection must have been made at the time the evidence was offered or the question
    was asked.” State v. Kinney, 
    171 Vt. 239
    , 253, 
    762 A.2d 833
    , 844 (2000) (alteration and quotation
    omitted). Defendant did not make such a timely objection as to either expert’s testimony.
    ¶ 93.   We conclude that neither Dr. Halikias’s nor Dr. Hagan’s testimony improperly
    vouched for A.B.’s credibility, as neither directly commented on A.B.’s credibility.
    ¶ 94.   Experts may not offer testimony that vouches, even implicitly, for another witness’s
    credibility. See State v. Catsam, 
    148 Vt. 366
    , 370, 
    534 A.2d 184
    , 187-88 (1987). In Catsam, we
    held that expert testimony that a child complainant in a sexual-abuse case had post-traumatic stress
    disorder, or PTSD, and that people diagnosed with PTSD generally do not fabricate claims of
    sexual abuse, was “the equivalent of a direct comment on the credibility of the testifying
    complainant” and was thus inadmissible. 
    Id. Similarly, in
    State v. Kinney, a case in which the
    defendant was charged with aggravated sexual assault, an expert for the State testified that the
    incidence of false reporting in rape cases was less than two percent.              We held this to be
    inadmissible because the jury could infer from the testimony that allegations of rape are almost
    always true, and thus that the complainant’s allegation was almost certainly 
    true. 171 Vt. at 253
    ,
    762 A.2d at 844. We affirmed the conviction, though, because admission of the improper
    testimony did not rise to the level of plain error. 
    Id. at 253,
    762 A.2d at 845.
    ¶ 95.   We likewise conclude that Dr. Halikias’s testimony does not rise to the level of
    plain error. This is a close case: the jury could infer from the testimony that because only a small
    percentage of children were induced to make false allegations, it was unlikely A.B. had been
    38
    coerced into falsely accusing defendant, and therefore she was likely telling the truth. We need
    not decide whether, upon a proper objection, the testimony should have been stricken; we conclude
    that any error does not rise to the level of plain error. See 
    id. (finding no
    plain error because we
    “cannot conclude that failure to exclude the inadmissible expert testimony caused a miscarriage of
    justice in this case”). Several aspects of Dr. Halikias’s testimony in combination support our
    conclusion that any error does not rise to the level of plain error. First, Dr. Halikias did not purport
    to give a global statistic; he emphasized that the statistic he related arose from a particular study.
    Second, his testimony as a whole emphasized how difficult it is to coerce children to falsely report,
    but also acknowledged that it can be done. Third, the testimony was a logical response to the
    testimony of defendant’s expert who described research suggesting that children can be coerced to
    make false allegations. And finally, the focus of Dr. Halikias’s testimony was not on the general
    truthfulness of children’s reports of sexual abuse but, rather, was on the susceptibility (or not) of
    children to coercion or suggestion inducing false allegations.23
    ¶ 96.   We conclude that admission of Dr. Hagan’s testimony was not error at all, let alone
    plain error. We have held in the past that a physician’s testimony that a child sexual-abuse
    23
    Defendant additionally argues that Dr. Halikias gave false testimony, violating
    defendant’s Fourteenth Amendment right to due process. In responding to defendant’s expert
    witness’s statement that there is a “divide in the field about research on children’s disclosure of
    sexual abuse,” Dr. Halikias said that is “not true” and that the “field is remarkably unified now
    compared to twenty-five years ago, or twenty years ago, in terms of understanding how children
    disclose.” On appeal, defendant submits numerous studies that he contends contradict this
    testimony. Defendant did not object to the admission of this testimony in the trial court, and does
    not actually argue on appeal that it is inadmissible—he just argues that it was false. The credibility
    of a witness, including an expert witness, is a matter for the factfinder to decide. State v. Sullivan,
    
    2018 VT 112
    , ¶¶ 17-18, __ Vt. __, 
    200 A.3d 670
    . Even if we understood defendant to implicitly
    argue that the testimony was inadmissible, in the absence of an objection, we would review the
    trial court’s admission of the evidence for plain error. V.R.Cr.P. 52(b). We find no plain error
    here. Defendant was free to cross examine the State’s expert with the studies he presents on appeal,
    to present contrary expert testimony, and to argue to the jury that the State’s expert’s assertions
    were false. Where reasonable minds can differ in interpreting the evidence, we will not substitute
    our own assessment of the state of research concerning children’s disclosure of sexual abuse for
    the jury’s.
    39
    complainant’s “tone was remarkably declaratory, remarkably specific” was simply a description
    of the complainant’s demeanor, “not tantamount to vouching for [the complainant’s] credibility.”
    Oscarson, 
    2004 VT 4
    , ¶¶ 65-66. Likewise here, Dr. Hagan was not vouching for A.B.’s credibility
    when he testified that her description of her sexual abuse was “significant,” “clear,” and “graphic.”
    Rather, he was describing his reasons for refraining from questioning A.B. about her history when
    she had just given a clear and graphic history to another.
    Affirmed.
