Mugglin, J.
Petitioner and respondent are the parents of three children, Erica (born in 1983) Richard (born in 1988) and Kevin (born in 1991). After they separated, a Family Court order was entered on May 28, 1992, based on their stipulation, awarding custody of the three children to respondent, with visitation rights reserved to petitioner. On this appeal, respondent seeks reversal of Family Court's order awarding custody of Richard to petitioner.
To warrant a change in a prior order of custody, a petitioner must proffer evidence of a significant change in circumstances showing a real need for change in the best interest of the child (see, Matter of Carnrike v. Kasson, 291 A.D.2d 680, 681). In addition, it must be shown that such change will "`* * * substantially enhance the child's welfare and the custodial parent is shown to be unfit or less fit to continue as the proper custodian'" (Matter of Stoesser v. Dunham, 260 A.D.2d 958, 959, quoting Matter of Buhrmeister v. McFarland, 235 A.D.2d 846, 847).
Here, the evidence of respondent's psychiatric problems, her hatred of petitioner, her attempts to alienate the children from petitioner, her inability to control the behavior of the children despite the intervention of outside agencies, the hospitalization of Richard on two occasions in a children's psychiatric hospital due to conflicts with respondent and his siblings, Richard's improvement when living with a maternal aunt, and petitioner's fitness as a parent overwhelmingly support Family Court's conclusions that there has been a significant change in circumstances and that it is in Richard's best interest that petitioner be his custodial parent. Family Court's findings have a sound and substantial basis in the record and will not be disturbed (see,Matter of Joshua QQ. [Harold QQ.], 290 A.D.2d 842; Matter of Bates v. Bates, 290 A.D.2d 732), as they promote the best interest of this child (see, Matter of Cornell v. Cornell, 290 A.D.2d 735).
