How to use
- Enter your baby weight in kilograms.
- Enter how many feeds per day you plan.
- Read the estimated daily total and the amount per feed.
Note
Good to know
- Watch your baby's hunger cues — a settled baby after a feed usually had enough.
- Always mix formula exactly as the product label says; never add extra water or extra powder.
- Use the estimate as a starting point and adjust with your pediatrician's guidance.
- Prepared formula should be used promptly and never kept longer than the label recommends.
Uses the commonly cited guide of about 150 ml per kg per day (typical range 120 to 180 ml per kg). Always follow the product label and your pediatric guidance, and watch hunger cues rather than forcing a set amount. Estimate only — not medical advice.
