God, I need help right now. DS is 22 months and since he was 18 months and in a big bed, has refused to go to sleep alone. We went along with this for a while but I find that, staying with him, I fall asleep too and end up without much of an evening. So we're trying to get him to sleep alone at bedtime by just putting him back every time he gets up. He gets into a real state and it's hell at the moment. Should i be nicer? He does fall asleep pretty happily if one of us is with him.
