What is the size of a two month old infant stomach?

A two-month-old infant's stomach is approximately the size of a large egg, holding around 3 to 5 ounces (90 to 150 milliliters) of milk at a time. This small capacity means that infants typically need to feed frequently, about every 2 to 3 hours. As they grow, their stomach size increases, allowing them to consume larger amounts of milk less frequently.
