Baby's Milk Intake Calculator
Estimate how much breast milk a baby needs per day and per feeding based on weight and age.
Formula
Daily intake = weight (kg) × 150 mL/kg; Per feeding = daily ÷ feedings
- WHO recommendation: ~150 mL per kg per day for 0–6 months.
- Range: 120–180 mL/kg/day depending on baby's hunger cues.
- Always consult your pediatrician or lactation consultant.
12 lb baby, 8 feeds/day
Inputs
- Baby Weight: 12 lbs
- Feedings per Day: 8
12 lbs = 5.44 kg. Daily = 5.44×150 = 816 mL = 27.6 oz. Per feed = 3.4 oz.
