How much breast milk does a 12-month-old (and beyond) need?

Typical breastfed ranges; your pediatrician has the final word · Updated July 2026

Quick answer: A 12-month-old (and beyond) typically takes 14 to 20 oz, tapering by choice per day, roughly as preferred per feed across 2 to 3 feeds. Every baby is its own baby: steady weight gain and wet diapers outrank any chart, including this one.

What this age is really about

At one year, whole cow's milk becomes an option and breast milk becomes a choice rather than a requirement. Families continue, combo, or wean on their own schedule; all three are wins.

The pumping-mom angle

The math flips from tracking intake to spending down: the Finish Line question stops being when can I stop and becomes how do I want this to end.

Bottle math for this age

Daily ounces ÷ feeds = the bottle. At 14 to 20 oz, tapering by choice across 2 to 3 feeds, portion storage in amounts near as preferred so leftovers never hit the 2-hour discard rule. Small bags waste less at every age.
