What is the appropriate size of an infant's stomach and how does it impact their feeding habits?

An infant's stomach is small, about the size of a cherry at birth and can expand to the size of a large egg by one year old. This small size means they need frequent feedings, usually every 2-3 hours, to meet their nutritional needs. Overfeeding can lead to discomfort and spitting up, while underfeeding can result in poor weight gain and development. Understanding the size of an infant's stomach is important for establishing healthy feeding habits.
