Baby's Milk Intake Calculator — Daily Recommendation by Age
Enter your baby's age and actual daily milk intake to see the recommended daily range and whether your baby is getting enough — or too much — milk.

How does this calculator work?
Recommended daily milk intake is ~780 ml/day for breastfed babies aged 1–6 months, and ~150 ml/kg/day for formula-fed babies. After 6 months, intake gradually decreases as solid foods are introduced. Enter your baby's age and actual intake to see whether they are within the typical 600–1000 ml/day window for their age.
Formula
How this is calculated
The reference ranges in this calculator are consensus estimates derived from two main sources: WHO 2009 longitudinal breastfeeding data (showing a remarkably consistent average of ~780 ml/day for exclusively breastfed babies from 1–6 months, largely independent of the mother's weight or the baby's size) and the weight-based formula guideline (150 ml per kg of body weight per day, scaled to typical median weights at each age). The two sources converge in the 700–900 ml/day range for the key 1–6 month period.
From 6 months onward, solid foods begin to replace milk as the primary source of energy and nutrients. The recommended milk volume gradually decreases — not because milk is less important, but because energy is increasingly coming from complementary foods. By 12 months, whole milk or continued breastfeeding at 400–600 ml/day alongside three meals provides adequate nutrition for most toddlers.
The ranges are intentionally broad because healthy babies vary. A breastfed baby's intake cannot be measured directly (weight-gain trends are the clinical proxy). For formula-fed babies, the daily total is more visible. In both cases, a baby who is gaining weight on their individual curve, has adequate wet nappies, and seems content is almost certainly getting enough — number matching the table is reassuring, but it is secondary to growth and wellbeing.
Frequently asked questions
Since breast milk cannot be measured directly, clinicians look at signs: at least 6 wet nappies per day, regular dirty nappies (especially in the first weeks), content behaviour between feeds, and steady weight gain following the baby's individual growth curve. A single feed amount cannot be reliably estimated without test-weighing.
If a formula-fed baby consistently finishes bottles and still seems unsatisfied, and weight gain is good, gently increasing each feed by 15–30 ml is usually the right response. For breastfed babies, frequent feeding is normal in the first weeks ('cluster feeding') — it stimulates milk supply and does not mean supply is low.
WHO and most paediatric bodies recommend exclusive milk feeding (breast or formula) for the first 6 months, then introducing complementary foods while continuing milk. Signs of readiness: sitting with support, loss of the tongue-thrust reflex, and showing interest in food. Introducing solids before 4 months is generally not recommended.
