i never saw your previous post, but your son sounds like mine, he was diagnoised with adhd at a young age, not hyperactive running around but lack of concentration not sitting still long going from one thing to another, mesy school work and now he is 17 his writing still looks like a spider scrawl, i am not saying that this is what is wrong with your son, but like others say you do have to consider all things, the frustration when things dont go his way, son was lego if he was building something and it fell apart he would shout at us all to shut up coz it was our fault, the ps2 was a constant battle as again he would get so frustrated with how each game was going
the money has only receantly started to ease as he is now has some money of his own

hope they find out whats up with your son and he gets the help he needs
