It depends on the babies weight and age. On average a baby should drink 2 ounces of formula or breast milk per pound each day. For example a 10 pound baby should drink around 20 ounces a day.But it depends on the baby, some need more and some need less. As long as your baby seems satisfied and is gaining weight properly, theres nothing to worry about.k for one i hope you mean formula, because babies dont need actual real milk until they are a year old anyways it all depends on your baby. some babies eat more, some eat less. my son was eating 8 ounces every 2-4 hours.
