Sleep training... Our 4 and a half month old is dependent on his pacifier for all sleeping and has physically hurt himself by rolling over on it w/ his face numerous times and I am so tired of replacing his pacifier every time he wakes up. What do I do? What does John say about sleep training? He is in a crib in our room since he still nurses 1X a night. We are planning to move his crib to his room when he is sleeping through the night. What do you recommend? Thank you so much.
