My son who is 9,has been losing his temper and self control probably since he was about 4, only over the past 3 or 4 they've became so violent i've become afraid of him. I've always noticed his temper but, call it denial, just passed it off as a "phase". He just loses it for the tiniest reason E.G. queueing up for a theme park ride, not getting what he wants (toys,games etc as we cant afford it). Sometimes there wont be any reason, he'll just flip out and start kicking walls, pick on his younger brothers, use threatening behavior sometimes resulting in actual physical violence towards me and his mum,swearing and stealing money. I could go on. I just want to know if he is just a bad kid because i went wrong somewhere or is there any illness behind this all?
