My 12 month old ds wakes at 5 am WITHOUT fail every single morning. As he is a poor feeder during the day and vomits alot (Gastric reflux - but thats another problem) I do get up and give him milk as I think he is genuinely hungry. He drinks 6 oz and goes back to sleep until 7.00 He seems to be programmed to wake at this time. How can I get him to sleep longer.
