Milk supply

How much breast milk a parent's body makes. It's driven by supply and demand: the more often milk is removed, the more the body makes.

What It Means

Milk supply is the amount of breast milk a parent's body produces. It works on supply and demand: WIC BreastfeedingBreastfeedingFeeding a baby milk directly from the breast. The AAP recommends breast milk alone for about the first 6 months, then alongside solid foods. See more Support explains that every time milk is removed, by the baby or a pump, the body gets the signal to make more, and over time it adjusts to what the baby takes. Frequent feeds in the early weeks help set that supply.

Try It: Count a Newborn's Feeds in 24 Hours

Slide to the number of feeds your newborn had in the last 24 hours. WIC's figure for newborns is 8 to 12 or more.

Feeds counted10
About one feed every (hours)2.4

That's within or above WIC's 8 to 12 or more for a newborn. Each of those feeds tells your body to keep making milk.

WIC's 8 to 12 figure is for newborns.

How Parents Say It

  • "I'm worried my supply is dropping."
  • "She's been feeding nonstop tonight, am I making enough?"
  • "I've been pumping after feeds to boost my supply."

The Breakdown

How supply works at each stage

StageWhat happensSource
NewbornNewbornA baby in the first 28 days of life, the stage doctors also call the neonatal period. See more weeks8 to 12 feeds or more every 24 hours; frequent feeds tell the body to make milkWIC
Growth spurtsGrowth spurtA short stretch when a child grows faster than usual in height and weight, common in the first year and again around puberty. See moreBabies may nurse longer and more often for a whileWIC
EveningsFeeds often bunch together, called cluster feedingCluster feedingWhen a baby wants several feeds close together over a few hours, often in the evening, instead of feeding at spaced-out times. See moreWIC; Cleveland Clinic
Birth to about 6 monthsBreast milk alone is the AAP's recommendationAAP, 2022 policy

Things that look like low supply but may not be. WIC and Cleveland Clinic say a baby who cluster feeds in the evening isn't necessarily short of milk. It may be a growth spurt, or a way of filling up before a longer sleep.

If supply seems low, per WIC

  1. Feed often: 8 to 12 times or more a day for a newborn.
  2. Try pumping between feedings.
  3. Remove more milk each time, or empty the breasts more often.
  4. If your baby isn't nursing well, express milk often so supply holds.

When to get help. If you're worried your baby isn't getting enough, or feeds are hard, call your pediatrician. A lactation consultant or your local WIC office can also watch a feed and help.

Good to Know

Supply is shaped by how often and how well milk is removed, so skipping feeds or replacing them with formula means fewer signals to your body. WIC Breastfeeding Support (wicbreastfeeding.fns.usda.gov) is USDA's site for these guides, including pages on supply and on pumping. Weight checks are the pediatrician's call, so bring any worry about intake to your baby's next visit, or call sooner if it can't wait.

FAQ

How can I increase my milk supply?

WIC suggests feeding often, pumping between feedings, and removing milk more often or more fully. Talk with a lactation consultant or your pediatrician if it doesn't improve.

Does cluster feeding mean I'm not making enough milk?

Not necessarily. WIC says evening cluster feeding can be a baby's way of filling up before a longer sleep, and growth spurts can make babies nurse longer and more often for a while.

How often should a newborn feed to build supply?

WIC says newborns feed 8 to 12 times or more in 24 hours. Each feed tells your body to keep making milk.
