My son, 8 years, has Aspergers.. and when something frustrates hims (which can be many things).. he screams at the top of his lungs and is in a rage! He is so frustrated! He will hit me, my wife, or whoever he disagrees with - the violence is terrible. This creates a massive, and unbearable stress on me and our whole family. What to do. We are exhausted and incredibly concerned. We love him very, very much.
