Thanks for the replys.
He does have a water battle all night so it is possible he is waking with a wet nappy. I think ill try changing him before i go to bed.
he has dinner about 6pm (he eats HEAPS) but then nothing til the morning so now that i think about it yeah, hes probably starving. We stoppping giving him a milk a few weeks ago (he'd usually have it in his cot when he goes down for the night). I guess he still needs something more.
Thanks again. Wish me luck
