Have been trying to get poor old DS (19 months) to sleep in his cot. Almost since birth he has come into our bed some time in the night, but recently has got too wriggly for it to work. For about a week he has been crying and yelling to come in and I've been going in his room two minutes, then four minutes, etc, putting him down again and going out. He does fall asleep eventually but it's pretty miserable. What can I do to make it easier for him? He has a nightlight and his teddy, but I wonder if there's something I'm missing, or the 'go-in put down go out' technique is not suitable for his age.
