K.A.
It sounds like she is waking a lot to feed at night, like maybe 4 times? My son dropped his second feeding (meaning he didn't want to eat when he woke up) around 4 months, and now he's 9 months and still usually will eat about 5 oz. 1 time at night. Sometimes he doesn't really want the bottle but wakes anyway. Is she finishing a bottle all those times? She's probably waking from habit and just wants comfort, so you could try not feeding her and getting her to go back to sleep. You could also try letting her cry if you feel comfortable. If she's eating like a couple oz. every time she wakes, she doesn't need to eat that often. If she's eating like a whole bottle at every night feeding, you probably need to ask your doc what's up. That said, every baby is different so do whatever seems right for you! :)
