DS goes to sleep easily at 19:00 but every 2/3 hours wakes then and cries, coughs himself into a state as he wants milk! We do try offering water. He is then awake from 05:30 and wants to play! We thought it might be a growth spurt but it's going on too long. We are not push overs either and do try the letting him cry game. Any ideas? We are exhausted! X
