Child Hitting Others in Kindergarten

My son gets in trouble in kindergarten because he hits his classmates and the teacher. He doesn't do this every day, but fairly frequently. We do a lot of yelling at home. Could this be part of the problem? The doctor says he does not have attention-deficit disorder. How can we help him turn things around at school and stop being so angry and hitting people? - Discouraged
Answer: The family discord might well be contributing to your son's behavior. Nobody in your family seems to have learned how to handle difficult situations. And children definitely follow in their parents' footsteps. The family yells, and he hits. This, of course, is no excuse for his behavior. Stop accepting such behavior at home. Your family might need counseling to turn things around for everyone.
As far as the school situation goes, it sounds like the teacher cannot handle the problem and needs help. It is rather amazing that she hasn't asked for it already. One possible step is an intervention in which one or more teachers at the school visit the classroom and offer suggestions. Another is for you and/or the teacher to ask that your child be evaluated by a team of school professionals to see what specific help he is eligible to receive in order to turn things around. Do this immediately. The earlier your son learns how to behave appropriately in the classroom, the fewer the problems that he will have later on.
