Victor M.], 119 AD3d 786, 787; Matter of Cory S. [Terry W.], 70 AD3d 1321, 1322; Matter of Patricia B., 61 AD3d 861, 862; Matter of Ivette R., 282 AD2d 751; Matter of Katrina W., 171 AD2d 250). The evidence presented at the fact-finding hearing established that, in July and August 2012, then-13-year-old Michael B. and his younger brother, then-7-year-old Lucas B., made independent and consistent out-of-court statements to several individuals describing three separate incidents when Michael B. sexually abused Lucas B. (see Matter of Jada A. [Robert W.], 116 AD3d 769; Matter of Tristan R., 63 AD3d 1075; Matter of Department of Social Servs. v Waleska M., 195 AD2d 507). Although the mother denied that she had any knowledge of abuse that occurred prior to July 9, 2012, the court's determination that she lacked credibility is entitled to deference and is fully supported by the record (see Matter of Sarah W. [Barbara G.F.], 122 AD3d 931; Matter of Cheryale B. [Michelle B.], 121 AD3d at 977; Matter of Rhiannon B., 237 AD2d 935). Moreover, although the mother separated the subject children by arranging for Lucas B. to reside with the maternal aunt on July 9, 2012, and sought treatment for Michael B. concerning his sexually abusive conduct on July 10, 2012, the evidence also demonstrated that the mother failed to take any steps to disclose the abuse or seek treatment for Michael B. prior to that time (see Matter of Kyanna T. [Winston R.], 99 AD3d 1011, 1013; Matterof Brian P. [April C.], 89 AD3d 1530; Matter of Aliciya R., 56 AD3d 784).

A.D.2d 751, 725 N.Y.S.2d 53 ; Matter of Katrina W., 171 A.D.2d 250, 575 N.Y.S.2d 705 ). The evidence presented at the fact-finding hearing established that, in July and August 2012, then–13–year–old Michael B. and his younger brother, then–7–year–old Lucas B., made independent and consistent out-of-court statements to several individuals describing three separate incidents when Michael B. sexually abused Lucas B. (see Matter of Jada A. [Robert W.], 116 A.D.3d 769, 982 N.Y.S.2d 917 ; Matter of Tristan R., 63 A.D.3d 1075, 883 N.Y.S.2d 229 ; Matter of Department of Social Servs. v. Waleska M., 195 A.D.2d 507, 600 N.Y.S.2d 464 ). Although the mother denied that she had any knowledge of abuse that occurred prior to July 9, 2012, the court's determination that she lacked credibility is entitled to deference and is fully supported by the record (see Matter of Sarah W. [Barbara G.F.], 122 A.D.3d 931, 997 N.Y.S.2d 164 ; Matter of Cheryale B. [Michelle B.], 121 A.D.3d at 977, 995 N.Y.S.2d 135 ; Matter of Rhiannon B., 237 A.D.2d 935, 654 N.Y.S.2d 537 ). Moreover, although the mother separated the subject children by arranging for Lucas B. to reside with the maternal aunt on July 9, 2012, and sought treatment for Michael B. concerning his sexually abusive conduct on July 10, 2012, the evidence also demonstrated that the mother failed to take any steps to disclose the abuse or seek treatment for Michael B. prior to that time (see Matter of Kyanna T. [Winston R.], 99 A.D.3d 1011, 1013, 953 N.Y.S.2d 121 ; Matter of Brian P. [April C.], 89 A.D.3d 1530, 933 N.Y.S.2d 792 ; Matter of Aliciya R., 56 A.D.3d 784, 869 N.Y.S.2d 140 ).

Respondent mother appeals from an order of fact-finding and disposition determining that she abused her two daughters. Contrary to the mother's contention, Family Court's findings of abuse are supported by a preponderance of the evidence ( seeFamily Ct. Act § 1046[b][i]; Matter of Peter C., 278 A.D.2d 911, 911, 718 N.Y.S.2d 551; Matter of Sarah C., 245 A.D.2d 1111, 1111–1112, 666 N.Y.S.2d 95; Matter of Rhiannon B., 237 A.D.2d 935, 935, 654 N.Y.S.2d 537). “We accord great weight and deference to [the c]ourt's determinations, ‘including its drawing of inferences and assessment of credibility,’ and we will not disturb those determinations where, as here, they are supported by the record” ( Matter of Arianna M. [Brian M.], 105 A.D.3d 1401, 1401, 963 N.Y.S.2d 895, lv. denied21 N.Y.3d 862, 972 N.Y.S.2d 219, 995 N.E.2d 182; see Peter C., 278 A.D.2d at 911, 718 N.Y.S.2d 551). It is hereby ORDERED that the order so appealed from is unanimously affirmed without costs.

as not a subject of this proceeding ( see Matter of Ian H., 42 AD3d 701, 702, lv denied 9 NY3d 814). The mother failed to object to the admission in evidence of the daughter's medical records on the grounds raised on appeal and thus failed to preserve her current contentions with respect to those records for our review ( see Matter of Pauline E. v Renelder P., 37 AD3d 1145, 1146; Matter of James E., 17 AD3d 871, 873). Contrary to the mother's further contention, the findings of abuse and derivative neglect are supported by the requisite preponderance of the evidence ( see Family Ct Act § 1046 [b] [i]). Petitioner established that the mother "knew or should reasonably have known" that her daughter was in danger of being physically and sexually abused by her adult son ( Matter of Sara X., 122 AD2d 795, 796, appeal dismissed 69 NY2d 707; see Matter of Lynelle W., 177 AD2d 1008), "and that `a reasonably prudent parent would have acted differently and, in so doing, prevented the injury'" ( Matter of Rhiannon B., 237 AD2d 935). The finding of derivative neglect with respect to the son who is the subject of this proceeding was proper because the mother, by allowing the daughter to be abused, thereby "demonstrated a fundamental defect in [her] understanding of the duties and obligations of parenthood and created an atmosphere detrimental to the physical, mental and emotional wellbeing of the son as well" ( Lynelle W., 177 AD2d at 1009; see Matter of Derrick C., 52 AD3d 1325, 1326, lv denied 11 NY3d 705).
