Ds is 6.10 and very bright and confident. He's in year 1 but easily doing year 4 maths work. He reads at least three school years above too. But he's out of control behaviour wise.
He completely disobeys everything I ask him to do. When I do ask him to do things he goes in to such a rage. Yesterday I asked him not to splash all over the bathroom while having a shower. I popped out and came back a minute later and the entire bathroom was soaking wet. I told him off and he screamed at me saying I was an idiot, so I sent him to bed (it was 6.15, his usual bedtime is 7.30) and he went in to total melt down. My solution was to make him lie on his bed until he calmed down and stop crying, which he did eventually, but he cannot accept obeying orders from grown ups. Every time I try and enforce rules he goes in to such a rage.
At school he's apparently very well behaved. He's a bit boisterous (his teachers words) in the playground but in class he's studious and hard working and concentrates brilliantly. I have spoken to his teacher about how he's said he's bored in class, she's trying to give him extra work to stretch him further, but I don't think that's the problem at all. He behaves really well at school, but at home he's utterly wild.
Any advice will be gratefully received because he's in danger of going totally off the rails and I'm worried if we don't make him understand now that he has to follow rules in life that he'll get in to serious trouble :(
