🍼 Feeding Calculator
Enter your baby's weight and feeds per day to estimate the daily formula or milk total and how much each bottle should hold, with a typical feeds-per-day table by age.
Informational only — not medical advice. Follow your pediatrician's guidance and your baby's cues.

What is a Feeding Calculator?
It answers the two questions every bottle-feeding parent asks: how much in a day, and how much per bottle? The daily figure comes from the documented 2.5 oz-per-pound rule of thumb pediatric guidance commonly publishes, capped near 32 oz; the per-bottle figure just divides that by your feeds per day, with a table of typical feed counts by age to sanity-check against.
It earns its keep on the road: knowing the day's total tells you how much formula to pack for the flight, how many bottles to prep for a road-trip day, and what to leave with a caregiver. Treat every number as a starting point — your baby's appetite, not the math, runs the show.
❓ Frequently Asked Questions
How much formula does a baby need per day?
The commonly published pediatric rule of thumb is about 2.5 ounces per pound of body weight per 24 hours — so a 10 lb baby takes roughly 25 oz a day — with intake typically capped around 32 oz regardless of weight. The calculator applies exactly that rule, converting from kilograms if that's how you weigh.
How much per bottle?
Divide the day's total by the number of feeds. A 25 oz day across eight feeds is a shade over 3 oz per bottle; the same day across six feeds is about 4 oz. Newborns take small, frequent feeds (8–12 a day); by 9–12 months many babies are down to 3–5 as solids take over.
Does this apply to breastfed babies?
Directly nursed babies self-regulate, so there's nothing to measure — the rule is most useful for formula feeding and for pumped-milk bottles (for example, when a caregiver feeds while you travel). Bottle-fed breast-milk amounts run in the same ballpark.
Is this medical advice?
No — it's an informational rule-of-thumb estimate. Babies vary day to day and feed to feed; hunger cues, wet diapers, and weight gain are the real gauges. Always follow your pediatrician's guidance on how much and how often your baby should eat.
