ds 4.5 has always been an early riser - 6ish but has started waking at 4.30 and not going back to sleep. he is totally exhausted. he had a bit of a cough which is now sorted and he started school in sept which meant he was going to bed a little earlier but only half an hour and in half term he has been going to bed at 7.
he is being good and staying in his bed til getting up time but i can hear him tossing and turning a d muttering and he is clearly awake the whole time. what on earth can i do?
