Thanks everyone.
I know he has too many things but its an accumulation over years of trying to find something that he likes. I was last night looking at buying a climbing frame!
He used to like books, he has over a 100 books, in addition to this he has children's wordsearch books, colouring books, crossword books Sudoku books, where's wally type books, etc etc.
He comes across as being spoilt but as I said we are just trying to find things that will occupy him, interest him.
I started doing a vegetable garden and he had his own section, he's now lost interest in that.
He does play minecraft, but again looses interest and starts being silly and knocking down his brother things after a while so he gets taken off it.
His behavior at school is good, he is still fidgety, rocking on his chair, saying he is bored, he keeps shouting out the answers instead of putting up his hands, again he gets into trouble for this but he says he can't stand it when people get it wrong, and it frustrates him.
His bed time routine is ok, he just doesn't need a lot of sleep, again he was referred to the hospital as he didn't sleep through until he started nursery, but he does now from about 10/10.30 until 5.30/6am.
I have tried to have friends over the last time being Friday just gone, its a disaster, he's ok for about an hour, then he keeps asking when they are going home, on Friday my DH sat with DS friend and played sky landers with him until it was the time for him to go home, as DS cried at the top of the stairs saying it was boring and he wanted his friend to go home.
His diet has always not been great, so we were refereed by the health visitor when he was little and we are now under the school nurse as he is quite skinny, but they aren't overly alarmed its just to keep an eye on him and his eating.
Thanks for all your suggestions, I have tried most of them, playing with him for a bit and then withdrawing so he can play on his own, but it doesn't work, he does help me clean from time to time, he loves baking, but there's only so many cookies and cup cakes you can bake in one week.
