My 8 week baby is only 6.5 pounds but HV's have been happy with her gain (born at 4 pounds) and she drinks around 18-20 ounces a day, across 9-10 feedings. Never more than two ounces in one go. Today she has wanted more at each feeding, which of course I give her but burping loads in between, as she does have reflux and I'm conscious not to overfeed. Is she looking to take more? How did you know when your babies were ready?
