What are the typical sizes of newborn stomachs and how can parents ensure they are feeding their newborns appropriately based on their stomach size?

Newborn stomach sizes are typically small, about the size of a cherry at birth and gradually increase in size over the first few days. Parents can ensure they are feeding their newborns appropriately by following their cues for hunger and fullness, feeding on demand, and offering frequent, small feedings to match their stomach capacity.
