How much milk should a newborn drink per day?

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.

How do I calculate how much milk my baby needs?

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.

How many ounces should a 3 month old drink?

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 - use our calculator for a personalized recommendation.

Is this calculator accurate for both formula and breast milk?

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.

How often should I feed my baby?

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 and consult your pediatrician.

What if my baby drinks more or less than the calculated amount?

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, content after feedings, and meeting developmental milestones. Always consult your pediatrician if concerned.
