The arm flapping is a self-stimulating behavior. Talk to your child's behavioral health specialist about that. Sometimes it takes a while to get the right dose of the right med. Unfortunately, the unique chemistry of each individual and their response to a med that is designed to balance chemistry can make medical treatment a bit of a crap shoot. He may need more medication or if he is at the max amount and the desired response is not achieved, another med might be indicated. Hang in there. I feel our pain. I have (2) 7 year olds, one with ADD and the other with ADHD, ODD , OCD, and anxiety.... I am running the gauntlet.
