My 7 year old son seems to be do exactly the opposite of what is asked. His mother & I have been divorced for 2 years now. He has been told repeatedly not to do something and then he does it anyway. While in time out or during any part of his punishment, he continues to act out, have an attitude, or shows anger towards me because I am the one who punished him. He also will NEVER admit responsibility for his wrong doings. He recently took an item that did not belong to him, and when confronted he swears he didnt do it. Then once proven that he did do it, he continues to lie about the extent of it. Even thou slowly the truth is coming out, he will deny all until days later when he has no more room to wiggle out of it. Then, again once punished, he is angry at me! Please offer some advise as to how to get him to listen & behave like a happy 7 year old.
