Breast Milk Calculator

Calculate how much breast milk your baby needs per feeding and per day based on age and weight.

How It Works

Enter your baby's weight and age in weeks. The calculator uses the standard 150-200 mL/kg/day guideline to estimate total daily breast milk needs and divides by typical feeding frequency for that age.

Formula

Daily Milk = 150โ€“200 mL ร— Weight (kg) | Per Feeding = Daily รท Number of Feeds
