My son is four and just started a new daycare in September. He has gotten progressively rougher with the children in his class. He pushes, shoves, hits and kicks others. I have never seen this behavior in him until the new school. I have tried rewards, punishment, bribes, and visiting school. They called again today about his behavior and are going to refer him for evaluation. What can I do to bring out the sweet boy that they are not seeing, before he becomes mis diagnosed with some sort of long medical terminolgy. He says he does not know why he is doing it. He promises every morning to be good, but cannot seen to keep his hands to himself.Please help. What can I do to calm him down and teach him to be gentle with others.
