MEMORANDUM AND ORDER
It is hereby ORDERED that the order so appealed from be and the same hereby is unanimously affirmed without costs.
Memorandum: Respondent appeals from an order granting the petition seeking to terminate her parental rights with respect to her son on the ground of mental retardation and to free him for adoption ( see Social Services Law § 384-b). Respondent's sole contention, that the evidence is insufficient to establish mental retardation because petitioner did not introduce evidence that the mental retardation originated during respondent's developmental period ( see § 384-b[6][b]), is not preserved for our review, and thus we do not address that contention ( see Matter of Star Leslie W., 63 N.Y.2d 136, 145; Matter of Lisa T., 247 A.D.2d 882, 882-883; Matter of Dixie Lu EE., 142 A.D.2d 747, 748).
