Get answers to the most common questions parents have about calculating and managing their baby's milk consumption.
Newborns (0-2 months) typically need 150-180 ml of milk per kg of body weight per day. For example, a 3.5 kg (7.7 lb) newborn would need approximately 525-630 ml (18-21 oz) daily, divided across 8-12 feedings. Our calculator gives you personalized recommendations based on your baby's exact weight.
To calculate your baby's milk needs: 1) Weigh your baby in kg or lbs, 2) Determine the ml/kg/day based on age (0-2 months: 150-180 ml/kg, 2-6 months: 120-150 ml/kg, 6-12 months: 100-120 ml/kg), 3) Multiply weight by the rate, 4) Divide by number of daily feedings for per-bottle amounts. Our free calculator does this math instantly for you.
A 3-month-old baby typically drinks 4-6 ounces (120-180 ml) per feeding, with 5-6 feedings per day. This equals roughly 24-32 ounces (700-950 ml) daily. The exact amount depends on your baby's weight—heavier babies need more milk. Enter your baby's details above for a personalized calculation.
Yes, this calculator works for both formula and expressed breast milk. The recommended intake volumes are based on general pediatric guidelines that apply to both types of feeding. However, breastfed babies may feed more frequently with slightly smaller volumes per feeding.
Newborns typically feed 8-12 times per day (every 2-3 hours). By 2-3 months, this usually decreases to 6-8 feedings. By 6 months, most babies feed 5-6 times daily. Always follow your baby's hunger cues rather than a strict schedule, and consult your pediatrician for personalized advice.
The calculated amounts are guidelines, not strict rules. Some babies naturally drink more or less. Signs your baby is getting enough milk include: 6+ wet diapers daily, steady weight gain, contentment after feedings, and meeting developmental milestones. Always consult your pediatrician if you're concerned about feeding.
Increase milk intake gradually as your baby grows and gains weight. Signs your baby may need more milk include: finishing bottles quickly and still seeming hungry, waking more frequently at night, and not gaining weight as expected. Recalculate using our tool monthly as your baby grows.
While this calculator uses standard pediatric guidelines, premature babies often have different nutritional needs. Preemies may require specialized formulas and different feeding volumes. Always consult with your neonatologist or pediatrician for feeding guidance specific to your premature baby.
During the first two months, babies have the highest milk needs relative to their weight at 150-180 ml/kg/day. A typical newborn weighing 3.5 kg (7.7 lbs) needs about 525-630 ml (18-21 oz) daily. Feedings are frequent— every 2-3 hours, or 8-12 times per day. Watch for hunger cues like rooting, hand-to-mouth movements, and fussiness.
Milk needs decrease slightly to 120-150 ml/kg/day as your baby grows. A 6 kg (13.2 lbs) baby at this stage needs approximately 720-900 ml (24-30 oz) daily. Most babies settle into a pattern of 6-8 feedings per day, with longer stretches between feeds, especially at night.
As solids are introduced, milk intake drops to 100-120 ml/kg/day. An 8 kg (17.6 lbs) baby needs about 800-960 ml (27-32 oz) daily from milk. By 12 months, babies typically have 4-5 milk feedings plus 3 solid meals. Milk remains the primary nutrition source until 12 months.
Your baby is getting enough milk if they have: 6+ wet diapers daily, regular soft stools, consistent weight gain (check with your pediatrician), contentment after feedings, and are meeting developmental milestones. If you're concerned, our calculator provides a helpful baseline, but always consult your healthcare provider.
Recalculate your baby's milk needs every 2-4 weeks as they grow. Weight gain of 150-200 grams per week is typical in the first few months, which means milk needs increase accordingly. Bookmark this calculator and check back regularly!
