When I read this and got to the cheese I had a thought. I run it by my DH and he agrees. Your little man is showing traits of giftedness. My DS is much the same with his stuff, and its because he has such a greater grasp of things that he is so melodramatic about everything. Harry has an absolute wet if any other kids go near his things because they might break them. He is much the same with his food or drink too - only we have it to the point now where we do say, fine, I'll put it away and you can have nothing, so he will eat what is on offer.

I would see if you can contact someone for support and advice, there are mothers groups for G&TC all over the show who are invaluable. I know you are in WA but the NSWAGTC are the best in the country to talk to. But I am fairly sure because fussing over a rectangular piece when the rest are square is so familiar to me. It has to be perfect for my Lyta too.

The good news is this too shall pass. As he gets older and understands what is going on around him better he will react more rationally to the situation.
