I guess the question is what are the consequences of his behavior? If there are none then he's just getting away with what he can. There has to be strict guidelines and consequences for his behavior. IE: When I take my kids to the park and they start throwing sand, I tell them to stop 1 warning, if they continue again we will leave, and I never give in we just leave. They know I will do whatever it takes if they misbehave. We have missed birthday parties, I have given them timeouts. BTW the best timeouts are the ones when they sit in a naughty chair in front of the tv and watch a channel in a different language, stocks, or if they are really bad CSPAN (it's amazing what kids will retain) which I can't even watch. If they cry or slouch they get more time. I know alot of people are against spanking, so I won't tell you that's what you should do, but when you lay down the law your child will learn to respect you and other authority. I don't think your child has ADD and I'm happy that he doesn't have any other health problems. I think that you can be very creative in both your rewards and your punishments. We also do chain links where if my son got 10 chain links for being good at school he got a prize. He really enjoyed that. But you do have to keep switching to what works best for you and your child. You probably know more what's best for him than any professional cause you live with him. I hope things get better for you and your son. :)
