How much formula should I feed my baby?

Question

Accepted Answer

Per the American Academy of Pediatrics (AAP) and the WHO infant feeding guidance, a healthy formula-fed baby typically needs about 150 ml of formula per kg of body weight per day from 1 to 6 months and about 120 ml per kg per day from 6 to 12 months once solids begin. A 5 kg newborn needs roughly 750 ml per day, and an 8 kg 6-month-old needs roughly 960 ml per day. Feedings per day drop from about 7–8 for newborns to 4–5 after 6 months, and the per-feed amount is the daily total divided by the number of feeds. This calculator only shows that recommended estimate and is not a medical prescription. For preterm, low-birth-weight, milk-protein allergy, reflux or poor weight gain, follow your pediatrician first. Appetite varies between babies; a ±10–20% difference from this estimate is normal.

Age	Per feeding	Feedings / day	Daily total
0–1 mo	1–3 oz / 30–90 ml	8–12 feedings	16–24 oz / 480–720 ml
1–2 mo	3–4 oz / 90–120 ml	7–8 feedings	24–28 oz / 720–840 ml
2–4 mo	4–5 oz / 120–150 ml	6–7 feedings	26–32 oz / 780–960 ml
4–6 mo	4–6 oz / 120–180 ml	5–6 feedings	28–32 oz / 840–960 ml
6–8 mo	6–8 oz / 180–240 ml	4–5 feedings	28–32 oz / 840–960 ml
8–12 mo	7–8 oz / 210–240 ml	3–4 feedings	24–32 oz / 720–960 ml
