the only way to fix it is to make him your shadow and you need to direct him to good behavior. It works trust me, its not going to work right away but once they discover that you are on them like glue they'll get it.

but I did have a child I did term. i stuck it out for almost a year. Every day saying that its going to be a good day, this child was the only one, who colored every where, bit the other kids, pullied thier hair, stole their toys and the last straw was that she was jumping on the other kids and trying to choke them. I discussed with the parents several times and got no one. When she left it was like a hundred pound boulder lifted from my home. The kids started to relax and play so well. Not one of the kids ever asked where the child was, I should have did it sooner.
