Breastfeeding Intake Calculator
Estimate how much breast milk your baby drinks each day based on age and weight, with feeding frequency and session duration.
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.
