In the first months, many parents ask the same question: is my baby drinking enough? A practical clinical reference is the ml/kg method used in paediatrics.
Our calculator estimates both daily milk volume and amount per bottle from age and weight — useful for formula and pumped breast milk.
Rule of thumb by age
- 0–6 months: around 150 ml per kg body weight per day
- from 6 months: around 120 ml/kg/day as solids are introduced
- upper practical limit: about 960 ml/day

Babies do not drink exactly the same amount every day. Growth spurts, mild illness, temperature, and sleep changes can all shift intake temporarily.
Focus on trend and clinical signs: wet diapers, expected weight gain, alertness, and comfortable feeding without repeated vomiting.

Bottom line
A baby feeding calculation is a practical guideline, not a diagnosis. Use the baby feeding amount calculator to structure daily feeds, and consult your pediatrician or midwife if intake or growth seems off.
