I agree that it could be a habit starting to form- which is very hard to grow them out of unless you start sooner rather than later. One other thing is, though, I believe that I was told that if you feed them enough for 24 during the day when they're awake, then they don't need to wake up at night to eat. I just read online that by 6 months, your baby should be eating about 32 oz per day, and taking in 6-8 oz per feeding. You might google this info yourself. It depends on your child's weight, too. Sounds to me like under 4 oz per feeding is too little for a 7 month old. If you can't grow her tummy a little bit, she won't be able to hold enough in there all night long, you know? I know my son slept through the night at 3 months, because I fed, fed, fed him all day (sure he spit up sometimes, but he wasn't terribly overfed- he didn't hurl everything up). I'd rather overfill their tummies, than underfill. He's always been average on weight (always in 50th percentile), so he's thrived well. Oh, and we never let my son cry it out. We also didn't let him form habits, either, though (needing to be fed, picked up, etc. for comfort in the middle of the night). You can go in and comfort her, but try not to pick her up and try to quit the night feedings, but only after you get her eating enough during the day. Hope this helps.
