Behavior school

My son is 5 and was put into a separate school for challenging kids. They have a zero tolerance policy. On the first day he was running and hiding, but was not being violent at all. By the fifth week he was starting to become violent at school. I was going to pull him from the school because I felt it wasn’t the right program for him, but was convinced by the professionals to have him stay. By the tenth week he was vomiting nightly at home. In school he was spitting, kicking, and biting teachers. One of his teachers told me that the reason my son doesn’t act that way at home is because I don’t have a rigid enough schedule. I finally pulled him from that school and have finally found this website and The Explosive Child and am working so hard with him. It is not easy, and I don’t know what next school year will bring, but it is so much better than it was with him being punished for things he cannot control.
