What is the appropriate size of a baby's stomach in relation to their age and feeding needs?

A baby's stomach size is small at birth, about the size of a cherry. It grows quickly in the first few days and weeks. By one month, it can hold about 2-4 ounces of milk. As the baby grows, the stomach size increases, allowing them to take in more milk or formula. It's important to feed babies according to their age and hunger cues to avoid overfeeding or underfeeding.
