Help with my 7 yr olds behaviour?

Let him come home from school and find his room STRIPPED of EVERYTHING but clothes and a bed. No tv, No video games, No computer anything, No family functions. This is going to be hard for you too but you have to instill in him now that YOU make the rules and call the shots. I think that idea about dinner sounds great. But here's what you do. Give him a warning that if things don't change there are going to be diar consequences. You take all his things out of his room when he misbehaves again just like I said, now part two of the punishment you lock him in his own room. Switch the doorknob and lock him in. If he cries, let him to a point, if it gets annoying, spank him. And tell him that now he does have a reason to cry. And every 30 min that he continues crying continue to go up there and spank him. But don't do the whimpy hit. Tear his behind up! He should be locked in his room from the time he gets home from school until the next morning, when its time for school again. And make sure you tell him the ONLY way things are going to change is if he behavior changes, and don't just buy whatever. You have to really show him this time he's too out of control. After a WEEK of good school reports he can have an hour of freedom(ie) come out of his room. But still no tv or video games or anything. Only being out of his room is a privilege. After week two you might extend it to two hours or so on and so forth. Email me if you have any more questions maya_yepez@yahoo.com
