McMURDIE, Judge:
¶1 Sandra R. (Mother) appeals the termination of her parental rights to her three children: M.R., born in 2008; F.M., born in 2015; and J.M., born in 2017. Sergio C. (Father) appeals the termination of his rights to their two children in common, F.M. and J.M. We affirm the termination orders and hold: (1) the court committed harmless error by allowing the Department of Child Safety (DCS) to introduce statements from scientific articles without meeting the foundation requirements of Arizona Rule of Evidence 803(18) ; (2) sufficient evidence supports the abuse finding related to the shaken-baby injury (nonaccidental trauma) even though the evidence did not prove which parent abused the child; and (3) under Alma S. v. DCS , 245 Ariz. 146, 425 P.3d 1089 (2018), the constitutional nexus requirement established by Linda V. v. ADES , 211 Ariz. 76, 117 P.3d 795 (App. 2005), is considered under the totality of the circumstances in determining whether termination is in the best interests of the child.
FACTS AND PROCEDURAL BACKGROUND
¶2 In 2013, Mother and her five-year-old daughter M.R. began living with Father. Mother subsequently gave birth to F.M. and J.M. In April 2017, six-week-old J.M. slept most of the day and vomited a lot that evening. Mother noticed that J.M.s arms began shaking at various times. Assuming it was a stomach issue, Father went to the store to buy tea for J.M. Meanwhile, J.M.s condition worsened. J.M. turned pale, started moaning, could not fully open her eyes, and her arms became stiff. After Father returned from the store, Mother and Father took J.M. to an urgent-care center where they waited more than 40 minutes for the doctor to evaluate her. Upon examination, the doctor told Mother and Father to immediately take J.M. to Phoenix Childrens Hospital (PCH).
¶3 At PCH, a scan revealed that J.M. had a large subdural hemorrhage on the left side of her brain and a smaller subdural hemorrhage on the right. She also had damage to her optic nerve and severe retinal hemorrhaging in both eyes. The hemorrhaging caused her brain to shift out of position and compress her brainstem. Because J.M.s life was in danger, doctors had to perform emergency neurosurgery. After surgery, Dr. Melissa Jones, a pediatrician with a specialty in child abuse pediatrics, evaluated J.M. After ruling out possible medical causes, Dr. Jones determined the injuries resulted from abusive head trauma and Mother and Father provided no alternative explanation for the cause of J.M.s injuries. PCH reported the injuries, and DCS took custody of all three children and filed dependency petitions. The juvenile court later established the case plan as severance and adoption.
¶4 In July 2017, DCS petitioned to terminate Mothers rights to J.M., F.M., and M.R., and Fathers rights to J.M. and F.M., under the abuse ground. See Ariz. Rev. Stat. (A.R.S.) § 8-533(B). Over seven months, DCS offered Mother and Father services, including hair-follicle testing to rule out drug abuse, psychological evaluations, individual counseling, and a parent aide during visits with the children. Although Mother and Father participated in services, in discussions with counselors, they continued to minimize J.M.s severe injuries and provided no further explanation for how the injury occurred.
¶5 The juvenile court held a three-day termination hearing. Dr. Jones testified for DCS, opining that J.M.s injuries resulted from nonaccidental trauma. Dr. Ruth Bristol, J.M.s pediatric neurosurgeon, testified on the manner and extent of J.M.s injuries. Mother and Fathers expert, Dr. Joseph Scheller, a pediatric neurologist with specialties in pediatric neurology and neuroimaging, opined that J.M.s injuries most likely resulted from an unusual complication of a birth injury. The court took the matter under advisement and later issued an order terminating Mothers rights to J.M., F.M., and M.R., and Fathers rights to J.M. and F.M. Mother and Father timely appealed. We have jurisdiction pursuant to Article 6, Section 9 of the Arizona Constitution and A.R.S. §§ 8-235(A), 12-120.21(A)(1), and -2101(A)(1).
DISCUSSION
¶6 To terminate a parent-child relationship, the court must find at least one statutory ground for termination under A.R.S. § 8-533(B) by clear and convincing evidence. Kent K. v. Bobby M. , 210 Ariz. 279, 284, ¶ 22, 110 P.3d 1013, 1018 (2005). The court must also find termination is in the childs best interests by a preponderance of the evidence. Id. We review the courts termination determination for an abuse of discretion and will affirm unless no reasonable evidence supports the courts findings. Mary Lou C. v. ADES , 207 Ariz. 43, 47, ¶ 8, 83 P.3d 43, 47 (App. 2004). The juvenile court is in the best position to weigh the evidence, observe the parties, judge the credibility of witnesses, and resolve disputed facts. ADES v. Oscar O. , 209 Ariz. 332, 334, ¶ 4, 100 P.3d 943, 945 (App. 2004).
A. The Court Committed Harmless Error by Allowing DCS to Cross-Examine Mother and Fathers Expert Witness with Publications in His Field Without Laying Proper Foundation.
¶7 Mother and Father assert that DCS failed to lay proper foundation for the scientific articles it used to impeach Mothers and Fathers expert witness, Dr. Scheller. Although we agree the court erred by not requiring DCS to lay the proper foundation for the publications, we conclude the error was harmless. See Monica C. v. ADES , 211 Ariz. 89, 94, ¶ 22, 118 P.3d 37, 42 (App. 2005) (harmless error applies in juvenile proceedings).
¶8 This court will affirm the juvenile courts evidentiary rulings absent a clear abuse of its discretion and resulting prejudice. Lashonda M. v. ADES , 210 Ariz. 77, 82-83, ¶ 19, 107 P.3d 923, 928-29 (App. 2005). Abuse of discretion occurs when a courts decision is manifestly unreasonable or based on untenable grounds. Id. (quoting Quigley v. City Court of Tucson , 132 Ariz. 35, 37, 643 P.2d 738, 740 (App. 1982) ).
¶9 Arizona Rule of Evidence 803(18) governs the admission of hearsay statements from learned treatises, periodicals, or pamphlets. Rule 803(18) provides that statements from such publications may be read into evidence, but not received as an exhibit, if:
(A) the statement is called to the attention of an expert witness on cross-examination or relied on by the expert on direct examination; and
(B) the publication is established as a reliable authority by the experts admission or testimony, by another experts testimony, or by judicial notice.
The learned treatise exception to the hearsay rule stems from [the] ... independent guarantees of trustworthiness of such works. Rossell v. Volkswagen of Am. , 147 Ariz. 160, 173, 709 P.2d 517, 530 (1985). By requiring the proponent to elicit an experts recognition of the publications reliability, Rule 803(18)(B) provides the proper method to verify the statements trustworthiness. See State v. West , 238 Ariz. 482, 500-501, ¶¶ 68, 70, 362 P.3d 1049, 1067-1068 (App. 2015).
¶10 Mother and Father argue DCS failed to lay the proper foundation before recounting statements from the scientific articles in the following two instances:
[DCS Counsel:] Okay. In Jones study, he concluded, again, that these are rare, but cannot be diagnosed unless nonaccidental head injury had been questioned thoroughly, do you agree with that statement?
[Dr. Scheller:] Yes and no. Its sort of-its a very complicated statement that he said. And Im happy to explain why or Ill just say-
* * *
[DCS Counsel:] And youre familiar with the Feldman study that was published in September of 2001?
[Dr. Scheller:] Yes, 2001. Because hes published a real lot of studies.
* * *
[DCS Counsel:] And [Feldmans] study found chronic or mixed chronic and acute subdural hematoma were found only in abused children in his study, thats what he found, correct?
[Dr. Scheller:] Yes.
Mother timely objected to each line of questioning, citing DCSs failure to establish that the publications containing the articles were reliable as required by Rule 803(18)(B). The court overruled each objection and found Dr. Schellers knowledge of the studies provided adequate foundation to question him about the contents.
¶11 DCS asserts it was not obligated to follow Rule 803(18) s foundation requirements during the cross-examination because it did not seek to admit the articles into evidence. We reject this argument. By asking Dr. Scheller to confirm its paraphrased descriptions of the articles findings, DCS put the truth of the findings themselves at issue. See Ariz. R. Evid. 801(c) (hearsay means an out-of-court statement offered to prove the truth of the matter asserted in the statement); Ariz. R. Evid. 802 (hearsay generally inadmissible); West , 238 Ariz. at 501, ¶ 71, 362 P.3d at 1068 (superior court properly sustained objection to prosecutors reference to the findings of a great deal of literature in scientific journals); Sharman v. Skaggs Cos. , 124 Ariz. 165, 168-69, 602 P.2d 833, 836-37 (App. 1979) (discussion of a reports findings on cross-examination introduced hearsay statements from report). Thus, before recounting the articles findings, DCS was required to first lay proper foundation concerning the reliability of the publications in which those articles appeared, or the reliability of the studies within the articles. DCS did not lay the required foundation, and the court erred by overruling Mothers and Fathers objections to DCSs improper cross-examination.
¶12 Although the court should have required DCS to establish the publications reliability before receiving evidence of the articles findings, we nonetheless conclude that the error was harmless. Dr. Scheller conceded his familiarity with each authority, was able to answer DCSs follow-up questions, and at times challenged DCSs attempts to restrict his explanations of the articles findings. While Mother and Father take issue with whether the referenced publications were current and credible, their respective counsel did not develop these arguments on redirect examination despite the opportunity to do so. And although the juvenile court ultimately rejected Dr. Schellers opinion, it based that decision on the testimony of J.M.s treating physicians and Dr. Schellers concessions surrounding the cause of J.M.s injuries, not whether Dr. Schellers opinion was contrary to the weight of published authority.
B. Sufficient Evidence Supports the Courts Order Terminating Mothers and Fathers Rights Based on Abuse or Failure to Protect from Abuse.
¶13 Mother and Father argue insufficient evidence supports the courts termination order under the abuse ground. A.R.S. § 8-533(B)(2) provides:
B. Evidence sufficient to justify the termination of the parent-child relationship shall include ...
* * *
2. [t]hat the parent has neglected or wilfully abused a child. This abuse includes serious physical or emotional injury or situations in which the parent knew or reasonably should have known that a person was abusing or neglecting a child.
If a parent abuses or neglects their child, the court may terminate that parents rights to their other children on this basis, even if there is no evidence that the other children were abused. Linda V. , 211 Ariz. at 79, ¶ 14, 117 P.3d at 798.
¶14 Reasonable evidence supports the courts finding that J.M.s injuries were caused by abuse. While in Mother and Fathers exclusive care, J.M. suffered a large subdural hemorrhage on the left side of her brain and a smaller subdural hemorrhage on the right. She also had significant midline shift and herniation of her brain, meaning there was so much pressure in the brain that it started to shift out of its normal position. J.M. required emergency neurosurgery to relieve the pressure because it had become so great that her skull could no longer contain the brain and its contents without threatening her life. She also had diffused retinal hemorrhages (or bleeding) in all quadrants of the retina and all layers of the retina. Her head injuries negatively affected a multitude of systems in her body. Post-trauma, doctors diagnosed her with cerebral palsy because she had significant motor impairment. She also suffers from regular epileptic seizures and is blind. She now requires occupational therapy, feeding therapy, and 24-hour monitoring. Dr. Bristol testified that J.M. will likely require long-term, full-time care for the foreseeable future.
¶15 At the termination hearing, Dr. Jones opined that J.M.s injuries occurred within a few days before her hospital admission and resulted from nonaccidental trauma. After reviewing the familys medical history and J.M.s birth records, Dr. Jones found no alternative medical explanation for her injuries. Similarly, Dr. Bristol testified that J.M.s injuries were most likely caused by recent trauma. Dr. Jones added that J.M.s lack of external injuries did not rule out abuse.
¶16 Dr. Scheller disagreed and testified that J.M.s injuries resulted from a subdural hematoma at birth that began spontaneously re-bleeding some weeks later, which in turn caused her retinal hemorrhages. Dr. Scheller conceded that this occurrence would be an unusual complication and that no other non-traumatic medical condition could have caused J.M.s injuries.
¶17 Dr. Jones and Dr. Bristol opined on Dr. Schellers conclusion, testifying that such an occurrence under the circumstances present with J.M. would be very, very rare. Dr. Jones testified that children [who] have spontaneous re-bleeding [also] have some other complicating factor with their brain. Dr. Bristol testified that in her experience as a pediatric neurosurgeon she had not seen a spontaneous re-bleed to that degree. Dr. Jones opined that J.M.s presentation and injuries did not correspond to Dr. Schellers theory, particularly the diffuse nature of J.M.s retinal hemorrhages, which was consistent with massive trauma with acceleration and deceleration. Regarding J.M.s eye injuries, Dr. Jones stated that:
[T]here had to be [a] significant force that led to that pattern of retinal hemorrhages. You can get retinal hemorrhages from many different causes, but the only times we see [J.M.s] pattern of retinal hemorrhages in the pediatric population is from abusive head trauma, severe motor vehicle collisions or theres some case reports of children who have fallen out of two or three story windows onto concrete.
Dr. Jones specifically distinguished Dr. Schellers theory, testifying that when the pressure is high in the brain, you can get retinal hemorrhages, but they are typically in the ... most recessed part of the retina ... surrounding the optic nerve, which was not the same pattern that [J.M.] had.
¶18 Throughout the investigation, dependency, and termination hearings, Mother and Father maintained that J.M. had suffered no accidents or injuries that would explain her injuries. At J.M.s first health checkup (a few weeks before her traumatic brain injury ), the doctor examining J.M. noted no concerns. Likewise, Mother and Father maintained that J.M. only began showing symptoms the evening they took her to the hospital. In sum, reasonable evidence supports the juvenile courts determination that J.M.s injuries were the result of nonaccidental trauma.
¶19 Based on its conclusion that J.M.s injuries were the result of nonaccidental trauma, the court also found that Mother or Father, or both, intentionally abused J.M. or knew or reasonably should have known that the other parent abused her, as she was in their sole care when she suffered life-threatening injuries. The court also found that, despite the timing, extent, mechanics and presentation of [J.M.s] injuries, Mother and Father continued to deny that abusive conduct occurred, presented a united front, and remained committed to each other and their relationship. And because neither parent had shown a willingness to leave the other to protect the children from the other parent, the court concluded that both parents have demonstrated their lack of protective capacities for all of the children, not only [J.M.].
¶20 Mother and Father have consistently maintained that they were J.M.s only caregivers since her birth. Mother and Father continuously denied J.M. was abused, even after they were confronted with PCHs medical assessments of J.M.s injuries. Despite strong evidence that at least one of them caused J.M.s injuries, Mother and Father made no attempt to distance themselves from one another. To the contrary, in the months following the incident with J.M., Mother and Father deepened their commitment to one another by marrying. Given this record, reasonable evidence supports the juvenile courts determination that: (1) one or both parents willfully abused J.M. by causing J.M.s physical injuries; and (2) one or both parents failed to protect J.M. after they knew or reasonably should have known J.M. had been abused. See Maricopa County Juv. Action Nos. JS-4118/JD-529 , 134 Ariz. 407, 408-09, 656 P.2d 1268, 1269-70 (App. 1982) (where mother refused to obtain a divorce or otherwise separate herself from husband who had committed abuse, her knowing failure to protect her children from abuse by her husband justified termination of her parental rights); see also Mario G. v. ADES , 227 Ariz. 282, 287-88, ¶¶ 19-25, 257 P.3d 1162, 1167-68 (App. 2011) (finding a fathers failure to protect one child from abuse justified termination of his rights to another child); Linda V. , 211 Ariz. at 79, ¶ 14, 117 P.3d at 798 (parents who permit another person to abuse or neglect their children may have their parental rights terminated). Once DCS established Mother and Father abused or failed to take steps to protect J.M. after the abuse occurred, the statutory grounds to terminate Mothers and Fathers rights to the other children were also met. A.R.S. § 8-533(B)(2) ; Linda V. , 211 Ariz. at 79, ¶ 14, 117 P.3d at 798. Accordingly, reasonable evidence supports the courts finding that termination of Mothers rights to J.M., F.M., and M.R., and Fathers rights to J.M. and F.M., was justified under A.R.S. § 8-533(B)(2).
C. Alma S. v. DCS Requires Courts to Consider the Connection Between the Prior Abuse of One Child and the Risk of Future Abuse to the Other Children During the Best-Interests Inquiry.
¶21 Mother and Father argue insufficient evidence supports the juvenile courts finding that there was a nexus between the abuse of J.M. and the risk of abuse to F.M. and M.R. In the past, this court has expressly held that termination of parental rights to a child who has not been the direct target of abuse requires the party seeking termination of rights to show, at the statutory-grounds stage, a constitutional nexus between the prior abuse and the risk of future abuse to the child at issue. Seth M. v. Arienne M. , 245 Ariz. 245, 248, ¶ 11, 426 P.3d 1224, 1227 (App. 2018) (quoting Tina T. v. DCS , 236 Ariz. 295, 299, ¶ 17, 339 P.3d 1040, 1044 (App. 2014) ); Mario G. , 227 Ariz. at 285, ¶ 16, 257 P.3d at 1165. This court recently revisited the constitutional nexus requirement, noting that it first appeared in a footnote in the Linda V. opinion, although that opinion does not identify any legal source for such a requirement and it is not present in the statute itself. Seth M. , 245 Ariz. at 248, ¶ 11, 426 P.3d at 1227 (citing Linda V. , 211 Ariz. at 80, ¶ 17, n.3, 117 P.3d at 799, n.3 ).
¶22 The uncertainty expressed in Seth M. towards requiring this showing at the statutory-grounds stage was realized when our supreme court issued its decision in Alma S. v. DCS . In Alma S. , the supreme court held the substantive grounds for termination listed in § 8-533(B) [are synonymous] with parental unfitness, and once the juvenile court finds a parent to be unfit, the best-interests analysis is triggered. 245 Ariz. at 150-51, ¶¶ 9, 12, 425 P.3d at 1093-94. Alma S. thus makes clear that, at the statutory-grounds stage, the juvenile court should only determine whether the party seeking termination has met its burden of proving a parent unfit under one of the grounds for termination. See Alma S. , 245 Ariz. at 154, ¶ 32-33, 425 P.3d at 1097 (Bolick, J., concurring in the result) (However, the Court today holds that all that must be proven by clear and convincing evidence is that the parent engaged in one of the statutory grounds for termination, which by itself constitute[s] a finding of parental fitness. (alteration in original) (quoting id. at 150, ¶ 11, 425 P.3d at 1093 ). Considerations outside the scope of A.R.S. § 8-533(B)(2) -such as whether a connection exists between a parents abuse of one of their children and the risk of abuse to their other children-are left to the best-interests inquiry. This conclusion not only comports with Alma S. s discussion of the two-step termination inquiry, but also Linda V. s original application of a nexus requirement. See Linda V. , 211 Ariz. at 80, ¶ 17, n.3, 117 P.3d at 799, n.3 (addressing the need to demonstrate a nexus between prior abuse and the risk of future abuse in the courts best-interests analysis).
D. Reasonable Evidence Supports the Courts Finding that Termination of Mothers and Fathers Parental Rights Served the Childrens Best Interests.
¶23 Once the court finds a parent unfit under at least one statutory ground for termination, the interests of the parent and child diverge, and the court proceeds to balance the unfit parents interest in the care and custody of his or her child.... against the independent and often adverse interests of the child in a safe and stable home life. Kent K. , 210 Ariz. at 286, ¶ 35, 110 P.3d at 1020. [A] determination of the childs best interest must include a finding as to how the child would benefit from a severance or be harmed by the continuation of the relationship. Maricopa County Juv. Action No. JS-500274 , 167 Ariz. 1, 5, 804 P.2d 730, 734 (1990) (emphasis omitted). Courts must consider the totality of the circumstances existing at the time of the severance determination, including the childs adoptability and the parents rehabilitation. Alma S. , 245 Ariz. at 148, ¶ 1, 425 P.3d at 1091. In cases where termination of a parents rights to one child is predicated on the parents abuse of another child, courts must also consider the connection between that abuse and the risk of future abuse to the child at issue. See Seth M., 245 Ariz. at 248, ¶ 11, 426 P.3d at 1227 ; Mario G. , 227 Ariz. at 285, ¶ 16, 257 P.3d at 1165 ; Linda V. , 211 Ariz. at 79-80 ¶¶ 14-15, 17, 117 P.3d at 798-99. When a current placement meets the childs needs and the childs prospective adoption is otherwise legally possible and likely, a juvenile court may find that termination of parental rights, so as to permit adoption, is in the childs best interests. Demetrius L. v. Joshlynn F. , 239 Ariz. 1, 4, ¶ 12, 365 P.3d 353, 356 (2016). Finally, [t]he existence and effect of a bonded relationship between a biological parent and a child, although a factor to consider, is not dispositive in addressing best interests. Dominique M. v. DCS , 240 Ariz. 96, 98, ¶ 12, 376 P.3d 699, 701 (App. 2016).
¶24 Here, based on its finding that Mother or Father abused J.M. or that they failed to protect J.M. from abuse, the juvenile court found that it had grave concerns about the parents protective capacities in the future. Mother and Father argue that the risk of abuse to F.M. and M.R. is remote because J.M. was a vulnerable infant, unlike the older children. But the juvenile court rejected this argument and concluded that by failing to take steps to protect J.M. from the unidentified abusing parent, Mother and Father have demonstrated they cannot or will not protect their children. The court specifically found that:
Although [M.R. and F.M.] are no longer infants, [they] are young children who are vulnerable. [M.R.] has already been the victim of child abuse by Mother in the past.[ ] Mother and Father ... have not been forthcoming about the cause of [J.M.s] injuries.
The court also found that given the parents persistent denials that any abuse occurred, both J.M. and her older siblings remained at risk of future abuse.
¶25 Reasonable evidence in the record supports these findings. M.R. was nine years old at the time of the termination hearing and F.M. was almost three-both still dependent on Mother and Father to meet their needs. Both parents actions after learning the nature of J.M.s injuries demonstrated they could not recognize danger and keep the children safe. As J.M.s primary caregivers, Mother and Father are the only ones in a position to explain how her injuries occurred. Mother and Father have refused to acknowledge abuse occurred or that at least one of them was responsible. Instead, they have remained together, and neither parent has taken steps to prevent the children from being returned to the same situation that led to J.M.s near-fatal injuries. On this record, we conclude reasonable evidence supports the courts finding that the abuse to J.M. bore a substantial connection to the risk of future abuse to the other children in Mothers and Fathers care.
¶26 Moreover, reasonable evidence concerning the childrens adoptability supports the juvenile courts best-interests finding. The case manager testified that F.M. and M.R. were in a kinship placement that was meeting their needs and the foster parents wished to adopt them. Due to J.M.s special needs, she was in a separate placement for a medically-fragile child that was providing her the specialized care she required. Although J.M.s placement was not willing to adopt, DCS identified other potential adoptive placements for her. Considering the childrens stability in their current placements, and the availability of adoptive placements, the case manager testified that termination would provide the children with a safe, secure environment, where all of their needs will be met. Reasonable evidence supports the courts finding that termination was also in the childrens best interests because of their adoptability.
CONCLUSION
¶27 For the foregoing reasons, we affirm the juvenile courts order terminating Mothers rights to J.M., F.M., and M.R. and Fathers rights to J.M. and F.M.
M.R.s fathers parental rights were terminated in the same proceeding. He is not a party to this appeal.
In 2011, while Mother went shopping, she left M.R., who was two years old at the time, unsupervised inside her car for 40 minutes. The temperature outside was 106 degrees. A police officer removed M.R. from the car before she suffered any serious injury, but Mother was arrested and subsequently pled guilty to child abuse.
