Whenever I have had to give DD a bottle, I have given her 4 oz, and she seems satisfied. My mom came over tonight to watch DD so I could get out(Bad day, I cried more often than not) and she made her a 6 oz bottle just to see how much she would eat. She downed the whole thing and didn't even spit up!
I am glad she wants to eat a lot, but now I am super paranoid, seeing as how when I pump I only get 2.5-3 oz total. I know the pump is not as effecient as baby, but that is a huge difference. Maybe I am not feeding her enough when she eats and that is why she is a terrible napper and is sleeping like crap at night lately?

Check out this page on kellymom.com. Be careful offering so much milk. When breastfeeding baby can control the flow of milk...on the bottle the milk comes out much faster than at the breast...so if you offer that much milk your baby will take it. So its starts a slippery slope causing your supply to go down. I bet you are feeding her fine as long as you feed on demand and let her nurse for as long as she wants.
