My little guy is 4 months old.. I used to be able to put him to bed awake and he would fall asleep. Over the past few weeks he will only fall asleep on the nipple then once he passes out I'll put him in his bed and he will sleep for about 15 min then wake up screaming... I will do this routine about 3-4 times then finally he will pass out and sleep the whole night. On the rare occasions he wakes up in the middle of the night he will suck his thumb and go back to sleep and in the morning he also will self sooth.. It's only at bedtime. My husband thinks he is too attached to my boob and that I need to stop giving it to him after his last feeding... I don't think there is anything wrong with comforting him... What are your experiences?
