My second son was drinking 8 ounces by the time he was about 5 months old. As long as they are getting full and eating it doesn't really matter how much they eat.
Usually breastfed babies only take about 2oz every feeding at that age. My son never took more than 4oz at a time up to a year. If you are pumping enough to keep up with that than that's great! I almost never pumped but when I did only got 4oz max from one side
@driastewart, you’re welcome! If she starts to get hungrier before the 2 hrs be careful to not over feed her, I made that mistake with one of my boys and he was constipated for days 😩
