You don't have to wake her up to feed her. Just let her sleep :) she will wake when hungry and probably eat anywhere from 4-6 ounces.
@evelynsmommy1208, how many ounces do i give her.... my baby sleep through the nighy too and wakes up every 3 to 4 hrs to eat... but recently i have to wake her up to feed her
It depends on your baby's weight gain and what your pediatrician says. My 10 week old is able to sleep through the night, but she wakes up every three hours like clockwork!
I feed her as much as she'll eat, it's really up to you. :) @lexismommy
