Normal Breastfeeding Facts

How much milk does my baby need?

  • Breastfed babies from one to six months take an average of 25-35 ounces per 24 hour day. (Breastfed babies take 20% of their overall calories at night!)
  • Research found that formula fed babies take on average 33% more milk per day than breastfed babies because breastfed babies digest breast milk more efficiently than formula. Formula fed babies need more calories just to maintain normal function because they are almost twofold less efficient at digesting nonhuman milk.
  • One breast or two? Depends on your breast storage capacity and your baby’s volume needs. Some mothers can store 4-5 ounces per breast, so baby would only need to eat from one at each feeding. Other moms can store 1-2 ounces and baby would need to feed from both breasts. Storage capacity is not indicated by breast size, but by glandular tissue in the breast. You will get to know your breast storage capacity as you get know your breasts and your baby.
  • Breast fullness between feedings only lasts the first two to three weeks as childbirth hormones are still active in the body. Breasts will begin to feel normal around one month and feeling of fullness will only happen if you have an unusually large milk production, miss a feeding or two, or go very long between feedings.
  • Research indicates that on average, babies take about 67% of the milk in their mothers breasts at each feeding, leaving on average 33% of milk behind in the breast. If a mother wants to increase her rate of milk production, she can increase the number of feedings or drain the breasts more fully.
  • Breastfed babies will take different amounts throughout the day.
  • Milk expression is a learned skill. One study found that 10% of moms whose babies were doing very well at the breast were unable to pump milk effectively. Pumping volumes do not indicate the volumes your baby can get at the breast.

 

Baby’s age Average ounces per feeding
Three days 1 ounce
One week 1.5 ounces
Two weeks 2-2.5 ounces
One month 3-4 ounces

 

The first week: By the end of your baby’s first week of frequent breastfeeding, milk production increases from 1 ounce per day on day one to 10-12 ounces per day by day five to seven. Baby’s stomach expands from the size of a large marble to the size of a chicken egg. Baby can take 1 ounce per feeding.

The second and third weeks: Baby can now hold 2-3 ounces at a feeding and takes 20-25 ounces per 24 hour period. Babies often increase the number and length of feedings due to growth spurts.

The fourth week: Baby can now take 3-4 ounces for a total of 25-35 ounces per day. Amazingly, at around one month you are producing just about as much milk each feeding as your baby will ever need.

One month and on: At around one month, a breastfed baby reaches her peak daily milk intake of 25-35 ounces per 24 hour period. This stays roughly the same through six months of age until she begins solid foods at six months.
