My son is 7.5 months old and weighs about 19-20 lb. He is still waking up usually once a night, always at different times (between 1 and 5 am). I have him on a 4 hr EASY:
7 wake/nurse
8:30 solids
9 nap (45 mins-2 hrs)
11 nurse
12:30 solids
1 nap (1.5-2 hrs)
3 nurse
4ish nap (45 min)
5:30 solids
7 nurse, bath, nurse, bed by 7:30
He doesn't always fully empty the breast at the 11 nursing, but other than that every time I put him to the breast he empties it (including in the middle of the night, and at that time I'm usually very engorged). Lately I've been trying to give him both breasts at each nursing, trying to increase supply and to get him to nurse as much as possible (supply has never been a problem for me). He eats a lot of solids, usually between 4-8 oz at each meal.
I'm fairly certain he's waking up at night because he's hungry, but I just don't know how to get more calories in him during the day, short of nursing him more frequently (which I was doing up until a few weeks ago, but with nursing on demand he usually woke up twice a night instead of only once).
We've never done dream feeds, he doesn't take a bottle (and I try to go to bed shortly after he goes to sleep anyway).
Any suggestions would be greatly appreciated!
