I don't know what to do. My sister has a severely autistic son who has started hitting her when he doesn't get his own way. He isn't violent at school, his social worker knows about him hitting her, she has been told to ignore him and not give him a reaction, he wants her to cry as he knows this is when she gives in. The problem is he is hitting and really hurting her, more now than ever, but she won't tell her husband because she knows he will say it time they thought about residental care for him. He's 13 and she isn't ready to think about that yet. He has hit one of the other children but she didn't tell the social worker. I'm concerned for her, she is like a battered wife she covers her bruises, I'm the only person she has told, but I know she's not telling me everything. Can I do anything? I feel like talking to her social worker, but is this the right thing to do? I am concerned about her and the other children.
