During the first week, most full-term babies take no more than 1 to 2 ounces (30 to 60ml) at feedings. This is because newborns' stomachs are so small. After 4 to 5 weeks, babies reach their peak feeding volume of about 3 to 4 ounces (90 to 120ml) and peak daily milk intake of about 30 ounces per day (900ml).
