No suggestions. Just want to say you are not alone. My first 2 would wake to nurse every 3-4 hours through the night and go right back to sleep. lLife was great. Babies were easy. This last one wants to nurse every 2 hours through the night and hourly during the day. NO he is not a newborn. The little stinker is a whopping 20 months old and of course on solids as well. He also has a similar sleep schedule as your lo. He goes down around 11pm and is up at 2am. It is 2am right now. He just woke up. I don't expect him to go back down until around 4 or 5 am. Sometimes he doesn't go down until 7:30 am.
