How Much Milk Does a Newborn Really Need?

breastfeeding babyMany new mothers are anxious to know if their babies are getting enough to eat. Especially for breastfed babies, it can be difficult to gauge just how much milk a newborn is actually drinking. Parents that are formula-feeding may overfeed a baby in order to finish a bottle while mothers who are breastfeeding may worry if they are producing enough milk.

The truth is, in the first few days of life, a newborn usually needs a lot less to eat than you may think. Some pediatricians at the hospital I work with maintain the belief that a breastfed baby can go 1 or 2 days with a few small feedings before they become concerned. They base this on the fact that a newborn generally has some “reserves” that they’ve built up to endure labor and delivery and may use their reserves as energy in the first day or so following birth.

Additionally, a newborn’s stomach is actually very tiny, especially on the first day.  

On his first day of life, a newborn’s stomach is actually only the size of a small marble.

A breastfed newborn will only be drinking a mother’s colostrum (the La Leche League has a helpful guide on colostrum here) which is like highly-concentrated super milk—think quality over quantity. So usually, even though it may look like you aren’t producing a lot of milk, it’s enough to fill your baby’s small tummy. You should aim to offer your baby the breast every two to three hours, timing from the start of one feed to the start of the next, with a goal of feeding 15-20 minutes on each side.

After about the second day, when your milk starts to change in consistency and volume, or if you’ve formula fed your baby right from birth, his stomach will expand to about the size of a larger, “shooter” marble. Formula-fed babies will usually eat 1-3 ounces every three to four hours.

By the end of your baby’s first week, her stomach will have expanded to the size of a ping pong ball and her feedings may increase as she goes through growth spurts. Be sure to talk with your pediatrician to ensure that your baby is on the right track with future feedings.

    I too, being a first time mom, wondered if he was getting enough breastmilk…until he was hitting the 95th percentile in both height an weight everytime we went to the pediatrician! If they’re growing at a steady pace there’s usually no need to be concerned. Interesting facts about their little tummies, but if you’re ever worried about their eating habits, a lot of hospitals in the US now employ lactation consultants that can help calm your nerves and teach new tactics. They visited me about 3 or 4 times in those first 2 days after he was born and taught me a few things. Now he’s 11 months and we’re still going strong! Good luck to all the new mommas out there and remember to stay calm and be patient! 🙂

    So glad to have read this article. I have an average size bust line (aka I think I’m small), and was concerned being a first time mom if I could feed my baby well enough without formula. This blog post was very reassuring along with other info on E.F. It contained information I was wondering about in clear professional detail unlike friendly advice from family and well meaning acquaintances
