I am a firm believer in the word "privilege". Playstations, tv, phone,toys, bikes, playing outside, sleep overs,.all privileges!~Make your son earn all of these! You dont want to "take them away" When you think of everything as a privilege, you son will soon realize that if he does not listen or do chores,homework,..he will not earn privileges. Taking things away that are material just doesnt seem to matter much. Emotionally, you want to point out his good behaviors, hug him, talk to him lovingly. If he does not have that,.he will act out. Encourage good behavior by noticing when he does well, dont point out the bad. Make a list of things you expect from him and put what he wants to earn beside it as a reward. Kids take for granted all of the little things. When they realize that everything has a price,I think you'll notice you get then to cooperate more! Good luck!
