Question: how many ounces of pumped breastmilk should a 4 week old eat?
Answer: There is no one right amount to feed babies, but there are some good rules of thumb. Most newborns take two or three ounces at a time and by 4 weeks, the average amount has gone up to four ounces. But in real life this may vary quite a bit from day to day and from baby to baby.
