Hi, I've got a question about my difficult child 1. He did great in the Residential Treatment Center (RTC). His aggression improved almost overnight. They did have a few problems there but nothing like the constant aggression I saw towards his siblings before he went in. He spent a year there learning new social skills, learning how to get his emotions out, lots of family therapy. He got out the end of Feb and his aggression is increasing towards his siblings. He got a new therapist when he got out of the Residential Treatment Center (RTC) and difficult child 1 isn't opening up to him. Sometimes he will use his 'new' social skill of going to a different room to calm down (we've actually been working on this for years.) The behavior chart doesn't work (they've never worked with him, but I still try. At least he gets rewarded for good behavior with it.) He does feel bad after hurting someone. He doesn't distinguish between hurting someone that is an accident and when its on purpose. Last time he hurt someone he put himself in time out for it. Any ideas would be helpful.
