Normal milk volumes

Birth through 24 months, for breast milk and for formula. These are averages across groups of babies — every baby's needs are different.

Which dataset?

Breast milk (at the breast, or expressed)

Systematic review

Human-milk intake rises fast in the first two weeks and then plateaus around 750–800 mL a day from about 1 to 6 months. Babies get more efficient rather than taking dramatically more.

Combination feeding? Read both datasets — the total sits between them, closer to whichever supplies most of the feeds.

What each age band usually looks like

Day 1 (0–24 hours)

Individual variation

Colostrum is measured in teaspoons, not ounces. A newborn's stomach holds roughly 5–7 mL — about the size of a cherry. Small volumes are expected, not a sign of low supply.

Days 2–3

Individual variation

Cluster feeding on night 2 is extremely common and is part of how milk volume is signalled to increase.

Days 4–6

Individual variation

Secretory activation ('milk coming in') usually happens between about 48 and 96 hours. Volume climbs quickly during this window.

Days 7–14

Individual variation

Most babies are back to birth weight by around day 10–14. Weight trend matters more than any single number.

2 weeks – 1 month

Individual variation

Exclusively breastfed intake plateaus around 750–800 mL/day and stays roughly flat until solids start — babies get more efficient rather than taking dramatically more.

1–2 months

Individual variation

A growth spurt around 3 and 6 weeks often looks like sudden constant feeding. It typically settles in 2–4 days.

2–3 months

Individual variation

Feeds often get shorter and more efficient. Shorter feeds are not the same as less milk.

3–4 months

Individual variation

Distractibility, shorter feeds, and softer breasts around 3 months are usually normal regulation, not a drop in supply.

4–6 months

Individual variation

Milk remains the complete source of nutrition through about 6 months for most babies.

6–8 months

Individual variation

Solids start alongside milk, not instead of it. Milk stays the main source of calories in this window.

8–9 months

Individual variation

Intake becomes more variable day to day as solids increase.

9–10 months

Individual variation

Some babies drop a feed here; others do not. Both are normal.

10–11 months

Individual variation

Solids are supplying a growing share of calories.

11–12 months

Individual variation

Nursing frequency often becomes tied to comfort, sleep, and reconnection as much as nutrition.

12–18 months

Individual variation

WHO recommends continued breastfeeding to 2 years and beyond alongside family foods, for as long as it works for both of you.

18–24 months

Individual variation

Intake at this age is driven mostly by the toddler. 'As desired' is the honest answer.

Expected variation

Normal feeding variation

Individual variation

Two babies of the same age and weight can differ by hundreds of millilitres per day and both be thriving. Some take small frequent feeds; some take large spaced feeds. The pattern matters less than growth, output, and comfort.

Growth spurts

Clinical experience

Periods of markedly increased feeding are commonly described around 2–3 weeks, 6 weeks, 3 months, and 6 months. They usually last 2–4 days. Increased feeding during these windows is how the supply signal is raised — it is not evidence that supply has failed.

Cluster feeding

Clinical experience

Several feeds packed close together, often in the evening, with fussiness in between. Very common in the first weeks and again during spurts. It is exhausting and it is normal. It does not, by itself, mean your baby is not getting enough.

When intake may differ

Limited evidence

Illness, teething, reflux, tongue mobility restriction, prematurity, cardiac or neurological conditions, medications, a strong or slow letdown, and returning to work can all shift intake. Persistent changes in feeding or output are worth a clinical review rather than a wait-and-see.

Before you read on

  • Many parents who experience these risk factors go on to breastfeed successfully.
  • Having one or more risk factors does not mean breastfeeding will be unsuccessful.
  • If feeding is not going as hoped, it is not a reflection of your effort or your worth as a parent.
  • Support from an IBCLC, your healthcare provider, or your baby's clinician can often identify what is getting in the way and build a feeding plan that works for your family.

Breast-milk ranges are drawn from ABM and AAP guidance, WHO infant feeding recommendations, and published research on exclusively breastfed infant intake, which plateaus around 750–800 mL/day from about 1 to 6 months. Formula ranges follow AAP/CDC formula-feeding guidance and the weight-based estimate of roughly 150 mL/kg/day in the early months, easing back as solids begin, with a commonly cited daily upper end of about 960 mL (32 oz) before solids.
