I EBF but occasionally I'll pump so that DH can give DS a bottle and I can get a little sleep. DS has never drank more than 2 oz at a time from the bottle (he's 12 weeks old). This doesn't seem like enough. When I pump, I can get 3-4 oz from each side, and I usually feed him one side at a time. Last night DH gave DS a bottle at 2am and he was up again hungry at 3am. I think it's harder for him to drink from the bottle than it is from the breast, he's always been a good latcher and an efficient eater. We're still using level 1 nipples, we tried going to level 2 but they were too messy, milk dribbled out of his mouth. Do you think it's time to move up to level 2 anyway? We're using Soothie nipples as these are the only pacifiers he would take and he seems to like the shape of them.
