My son will not listen to me or his father. He acts like he doesn't hear us or that he doesn't understand. If he doesn't get his way he screams and throws things. At preschool he is always getting in trouble. He dosen't want to listen, or do what the others are doing. We have to tell him several times to stop what he is doing. When I pick him up from school, I ask the teacher how his day went, she never says good or great - it is always we had this problem or that problem. I have 2 girls ages 9 and 7 and I never had these kinds of problems. He can be sweet andgood!! When he wants too. I do not know what to do. How do I get him to listen to us, with out yelling,repeating myself 100 times, or fighting with him. He has alot of energy. It is hard to keep him on one thing for very long. I love him very much, but sometimes I do not think he is normal. Is he?
