In Diament v. Isaacs (24 Misc. 2d 1026, 209 N.Y.S. 2d 406 [Mun Ct, Kings County 1960]) the issue of child care in residential apartments came to the fore in finding that the care of three small children during the daytime hours did not constitute a substantial violation of the tenancy, the court noted that "[t]he proper care of working mother's children is a basic social and economic problem of our time and society. The construction here sought by the landlord would have a crippling effect on an indispensable social technique." (Id. at 1027-1028.)
