Hello, I am new to the forum. I have a 7 year old son with ADD. He currently takes concerta and is doing pretty well in school. However, something happened today that frightens me. He was on recess with hid classmates. This includes his 6 year old brother. My 7yr old and one of his friends trapped my younger son behind the building. The friend was holding my younger sons arms back while my eldest child punched his own brother. When the teachers confronted the boys I was told that my 7 yr old new what he had done was wrong, but he had no emotional response to the event. I can't tell you how concerned I am at this point. My son has had issues with aggressiveness at school before, but not even close tot his extent. Does anyone have any advise on how I can talk to him about this? I want to know why this happened. Also, will punishment help this situation? How extreme can I/should I go with a punishment? Any help is greatly appreciated.
