How Much do Babies Eat?
A newborn's tummy is very small, especially in the early days. Once breastfeeding is established, exclusively breastfed babies from 1 to 6 months of age take in between 19 and 30 ounces per day. If you breastfeed 8 times per day, the baby would eat around 3 ounces per feeding. Older babies will take less breast milk as other food is introduced.
Every baby is different though. At birth, the baby's stomach can comfortably digest what would fit in a hazelnut (about 1-2 teaspoons). In the first week, the baby's stomach grows to hold about 2 ounces or what would fit in a walnut.
