Order unanimously affirmed with costs. Memorandum: Family Court properly denied respondent's objections to the Hearing Examiner's order. Respondent failed to demonstrate an unforeseen substantial change in circumstances warranting a downward modification of child support (see, Stock v. Stock, 202 A.D.2d 914, 915). Further, respondent's child support obligation was properly determined on a per-household rather than a per-child basis (see, Buck v Buck, 195 A.D.2d 818; Matter of Niagara County Dept. of Social Servs. [Maxwell] v. Cunningham, 188 A.D.2d 1039; Matter of Griffin v. Janik, 185 A.D.2d 635).
