A baby’s stomach is approximately the size of a cherry when it is first born and can contain 5–7 mL of milk. In the next 3 days, it grows approximately 4 times to the size of a walnut and can now hold 22–27 mL of milk. By 7 days, it will increase 9 times in size (about the size of an apricot) and can hold 45–60 mL of milk. When the baby is a month old, their stomach is about the size of a large egg, and can hold approximately 80–150 mL of milk.

This is easy to see why babies need to be fed every few hours during their first few weeks of life.
As they continue to get older and grow, they will consume larger quantities of formula with longer periods between feedings.
How to determine if your baby is eating enough
Proper weight gain is the truest test as to whether or not your baby is eating enough. The number of wet diapers is also a good indication. If you get 6 or more per day, and your baby is content between feedings, they are likely satisfied.
It is important to follow your baby’s cues when they are nursing to determine when they have had enough. Don’t try to force them to continue feeding when they are not hungry. When exclusively bottle feeding, the below guide will give you an approximation as to how many bottles and how often you should feed formula to your baby. Remember though, these are just averages…Your baby’s appetite is always the best guide.
