How Breastfeeding Intake Is Estimated

Unlike formula feeding, breast milk intake cannot be precisely measured from feeding. This calculator uses the validated research baseline of approximately 750 ml/day for exclusively breastfed infants at 1-6 months, adjusted for your baby's weight.

Weight adjustment: The base is scaled proportionally to weight (750 ml × weightKg/6), capped at 900 ml/day to reflect physiological limits.

After 6 months: Daily intake is reduced by approximately 20% to account for solid food supplementation, consistent with observed intake patterns in breastfed infants after solids introduction.

These are estimates only — actual intake varies by baby, feeding style, and breast milk composition.
