My boyfriend has a little boy that will be 5 this January. He lives primarily with his mother and her boyfriend. His mother, her boyfriend, their two younger sons and a new baby daughter all sleep in the same bedroom. Sometimes his mother sleeps downstairs, so that leaves the boyfriend in their with 4 kids under the age of 5 and one not his. We are not happy with these arrangements but his mother gets irrate every time we bring this up. Is this legal in New York State??
