Yael, it's important that you get your rest as well. It's no good for you, being worn out all the time. Believe me, there is a big difference between what is traditionally known as controlled crying and allowing your child to lie in his bed, grizzling for a while before nodding off. As per Kelly's post, I've found Pinky's books are really helpful. Lots of good tips. Another good one someone gave me was called "The No Cry Sleep Solution" by Elizabeth Pantley.

Just a thought ... I'm wondering (as you mentioned you don't wrap him now) whether he has a sleeping bag and if that might help? Just in case he is waking himself up by kicking off the covers and getting cold. I know mine does that if not in his sleeping bag.
