I have a son that just turned 7. We have met with the teacher at his school because he tends to become very frustrated if he can't figure something out then he shuts down and crys or explodes and yells. He is a very stubborn little boy. He comes from a good family my husband and I have been married for 8 years. He has a little brother who is 3yrs old. I can't figure out how to help him.
