Estimates a breastfed infant's typical daily milk intake using the commonly cited general reference range of approximately 150-200 mL per kg of body weight per day (a widely referenced average used in breastfeeding/lactation education, e.g. as summarized in AAP and WHO infant feeding materials). This is a general population-average reference range, not an individualized feeding prescription — actual intake varies significantly by infant, age, and feeding pattern. Consult a pediatrician or lactation consultant for actual feeding guidance.
How it works
Enter your baby's weight in kilograms and the number of feeds per day. The tool applies the 150-200 mL/kg/day reference range to estimate a daily intake range, then divides it across feeds.
- Enter baby's weight (kg).
- Enter number of feeds per day.
- Click Calculate to see your results.
Examples
4.5 kg baby, 8 feeds/day
Daily intake ≈ 675-900 mL/day, or about 84-113 mL per feed across 8 feeds.
Who should use it
- New parent feeding-planning reference.
- Lactation education.
Industry applications
- Lactation and pediatric nutrition education
- Parent/caregiver reference
Advantages
- Simple, widely-cited general guidance range.
- Shows both daily and per-feed estimates.
Limitations
- A general population average, not individualized medical advice.
Common mistakes to avoid
- Treating the low end or high end of the range as an exact target rather than a normal reference band.
Best practices
- Track wet/dirty diapers and weight gain as additional signals, and consult a pediatrician or lactation consultant for individualized guidance.
Tips
- Breastfed infants often self-regulate intake more than formula-fed infants — use this as a general reference rather than a strict target.
