Ordered that the order of disposition is affirmed, without costs or disbursements.
Contrary to the appellant's contention, the late disclosure of certain Rosario material ( see People v Rosario, 9 NY2d 286, 289, cert denied 386 US 866 [1961]; Family Ct Act § 331.4 [a]) during his fact-finding hearing does not require reversal. The appellant failed to demonstrate that he was substantially prejudiced by the delayed disclosure ( see People v Banch, 80 NY2d 610, 617; People v Chia Yen Yun, 35 AD3d 494, 495) as the Family Court gave the appellant the opportunity to recall certain witnesses for further cross-examination ( see People v Gutierrez, 273 AD2d 251; People v Farner, 234 AD2d 561, 562; People v Leon, 186 AD2d 587, 588).
The appellant's remaining contention is unpreserved for appellate review.
