I was hoping the vacation would get him out of that routine. I was wrong. He spit, hit, kicked, bit, cursed, screamed, and threw furniture at school today in response to being asked to sit down even if he wasn't going to do his work. He had to be restrained. This is exactly what was happening every day before we left for vacation. It happened some thru vacation, but not daily. This has to stop. "Positive reinforcement" is not happening fast enough, if at all. Any ideas?
