Hi weve been asked by our pead to do sleep diaries for Melatonin. But im not sure if its what we want. Sleep issues with both but in different ways. Both aged 3 (nearly4) both diagnosed ASD. DS1 goes to sleep fine about 7/7.30 and sleeps ok initially but then after a few hours will wake every hour all night screaming for milk. Tried leaving tried lying with tried everything he will go on forever! DS1 sleeps quite well once he gets to sleep but will bounce off the walls all night and it gets to nearly midnight then hes so tired anxious and upset in a morning when he has to get up? Would melatonin work for both of them? Or just for ds2 where the issue is going to sleep?
