DS is 13 months. Each night he wakes crying at 3.45 for about 1.5 hours and I can't do anything to help him. Can't resettle in cot, he will take a feed but screams as soon as off boob, won't be cuddled, stroked, screams in our bed, screams if put back in cot, painkiller doesn't help, not hot/cold, change doesn't help. What am I missing? I feel awful for him and so frustrated. He'll eventually go back off out of sheer exhaustion for maybe an hour then up for the day around 6.
