MY husband and I have 2 children and his brother and wife have a little boy. They are drug addicts and can't seem to stay in one place. My husbands brother has bipolar disease and when he gets angry he hits our nephew his wife does aboslutly nothing except lock herself in the bathroom but we have no proof! I really want to get my little nephew out of that house but I need help about who to call and where to start

Child Protective Services or your local equiv. Call the police station - they will direct you.
