Thanks everyone. Glad to see he isn't the only super surly 4 year old around.

I should have added that this isn't a passing thing - he has been doing it for at least the last 3 months. Don't get me wrong, he can be such a nice kid when he is good, it can just go bad so quickly. It is way better on kindy days. Staying at home is a complete nightmare.

G and MP, thanks - I do appreciate the honesty. The GP did refer us to someone about the sleep and I was going to bring up the behavior stuff then. He is acting like he was back before we started kindy, when he needed more stimulation. Perhaps there is something in this 'gifted' thing like his teachers say. I really hope that he hasn't outgrown kindy, it is still 6 months before he starts school.
