Sometimes teens need to have some time away from their families. They may want to move out of the family for a while. Many parents will say no to this demand. But experts say it might be a good idea to let your teens live with a friend or relative.

“It was the break I need at the time,” said Richard Lerner. He is talking about the time he spent living with his grandmother when he was 15.

“It allowed me to be a different person than I was with my parents,” Lerner said. He now heads the Institute for Children, Youth and Families at Michigan State University.
