Adoption of sibling, OMG tantrums, Please help? We are in process of transitioning 3 year old sibling to our previously adopted twins who are almost 5. This poor litlle guy has had major trauma with being removed from his home and placement. The biggest concern we have is when he gets really mad he will throw his head against objects or the floor. One time he picked up a little childrens chair and threw it and screamed. I told him I would not listen to him do that and when he was done to please pick up the chair and put it back. I walked away and a couple of minutes later when he was quiet, I saw that he HAD in fact put the chair back and said sorry. I asked if he was feeling better, he said yes and we hugged it out and I told him that the behaviour is not aceptable and I don't want him to keep hurting himself. He has major speech and language delays. Any advice on how to help a child that hurts himself? We predict this scenerio when leaving a fun activity/place as well. Any coping techniques? Not hitting, please. Transition help?

Summarized question: Could you please recommend any coping technique to help a 3-year-old child not hitting himself?
