DS keeps waking at about 5am and I don't think it's 'cos he's hungry. I don't mind leaving him to cry for a bit, but the problem is that if I go in to reassure him, he pulls himself up on his cot bars and holds his hands out to me. I don't know whether to pick him up or to leave him standing and hope he'll go back to sleep. He can get down from standing so he's definitely not stuck... Any thoughts?
