I have a 15 week old baby boy and he will tend to have an initial sleep of 4-5 hours and then wake every two hours. I'm pretty sure that he is not hungry in most of his wakes. I am currently sleeping in the nursery next to his cot. On a couple of occasions, I have just waited and he goes back to sleep in a few mins. However, if there is a prolonged cry, should I keep waiting? Is sleeping next to him but not comforting him an aggravation? When I do comfort him, it clearly stimulates him and it's rare I can get him back to sleep without feeding him. I thought that cry-it-out methods should be done when you are not in the same room (although I do not plan to leave him for more than 10 mins). Any thoughts?
