My son struggles to go to sleep at 7ish but then is fine until 10:30 feed (bottle) and happily sleeps till 4ish. I then breastfeed at 4 but he will not go back to sleep after this feed unless he is cuddled and held the whole time. You just cannot put him down. He doesn't seem to be tired at this time. It is absolutely breaking me!! I have cried this morning cos I am so very tired. He is 12 weeks btw. Any suggestions?
