When babies are born, their tummies are only about the size of a cherry and can hold about 1-1.5 teaspoons of milk. Therefore, during the first month of life 1-3 ounces of milk per feeding is adequate. If you plan to continue breastfeeding, it’s best to breastfeed as much as possible during this time and not introduce a bottle until 4-6 weeks. However, if you need to give a bottle, 1-3 ounces per feeding should be sufficient during the first month. The great thing about babies is that they are intuitive eaters, which means they will let you know if they are still hungry and want more. Likewise, they will stop when they are full. From one month old and beyond, 3-4 ounces of milk is recommended per feeding.
