my 7 year old destroyed his bedroom as we said he can't go outside after back chatting and refusing to get changed out school uniform.
He tipped every toy out his toy box including Lego and a bag full of pens and pencils, pulled all his clothes out his wardrobe including the pole, dvds flung all over the place. Literally like a tornado came through his bedroom.
He's refused to clean it and has said he don't want to clean it, he would rather we do it for him.
We said if we do it were bagging it all up and taking it away... he don't care, he said throw them away then 
We have literally ran out of punishments to give till its done, he still don't care.
When he's sat up there attempting to Do it he draws all over himself and his stuff.
This morning I had enough and said I would guide him telling him what to do, BUT im not helping as he done it all himself so he has to learn, still didn't help even me being there telling him.
AIBU not helping him clean it up? And what would others do?
