I am really in need of some advice. My 5 yr. old son has a very aggessive, controlling behavior around other children. He wants to always control the activity and gets angry and mean when his friends don't comply. He has major impulse control issues and doesn't take "no" and takes whatever he wants. We find him stealing food and hiding it in his room. He also constantly invades peoples personal space with hitting, grabbing, jumping on and he always laughs when he gets in trouble and likes to mock. It is constant. At pre-school when a child has a party, everyone in the class seems to be invited except our son. He has 2 boys that he has been friends with for years and last year the other moms basically kicked us out of their playgroup and openly excludes us. Part of me is furious at these parents and the other part of me understands. I hurt so much for him because he has a huge heart and is exceptionally bright and outgoing. We have tried so many different things such as time-outs, spankings, change of diets (feingold), major discussions about social behavior and responsibility. We have books about being a good friend but nothing is working. He starts Kindergarten in August and I want this resolved so he learns to make friends and keep them. Please help me....we love him so much.
