Question: how many ounces of breastmilk should 3 week old eat?
Answer: Because newborns' stomachs are so small, during the first week most full-term babies take no more than 1 to 2 ounces (30 to 60 mL) at feedings. After about four to five weeks, babies reach their peak feeding volume of about 3 to 4 ounces (90 to 120 mL) and peak daily milk intake of about 30 ounces per day (900 mL).
