About this tool

This tool helps parents feed a baby formula safely, step by step. Tap your baby’s age, the kind of formula you use (powder, liquid concentrate or ready-to-feed), and its type. The page then shows how much to feed and exactly how to mix one bottle. You can add your baby’s weight to see a daily total.

It explains the common formula types in plain words: standard cow’s milk–based formula (right for most babies), partly broken-down “gentle” formula, lactose-reduced formula, extensively hydrolyzed (hypoallergenic) and amino acid–based formulas for milk allergy, soy formula (only for a few reasons, and not advised for babies born early), anti-reflux (AR) formula, and preterm or after-NICU formula. The special formulas are meant to be used on a doctor’s advice.

Mixing depends on the form: powder is level scoops added to water (most US cans say 1 scoop to 2 oz of water), liquid concentrate is mixed with an equal amount of water, and ready-to-feed gets no water at all. Never add extra water or extra powder. Amounts follow the American Academy of Pediatrics (HealthyChildren.org); mixing and storage follow the CDC, FDA and WHO.

Common questions

How much formula should a newborn drink?

In the first week, about 1–2 oz per feed is enough, every 2–3 hours (8–12 times a day). Babies slowly take more and reach about 3–4 oz per feed by the end of the first month. Follow your baby’s hunger and fullness cues.

Which type of formula should I use?

Most babies do well on a standard cow’s milk–based formula with iron. Store brands meet the same FDA rules as name brands. Hypoallergenic, amino acid–based, soy, anti-reflux and preterm formulas are for special cases; use them when your baby’s doctor suggests it.

How do I mix powder, concentrate and ready-to-feed formula?

Powder: pour the water first, then add level, unpacked scoops with the scoop from that can, as the label says (most US cans: 1 scoop to 2 oz of water). Liquid concentrate: mix equal amounts of concentrate and water. Ready-to-feed: pour and feed, with no water. Never add extra water or extra powder.

How long can mixed formula sit out?

Use mixed formula within 2 hours, and within 1 hour after the feed starts. If you won’t use it within 2 hours, put it in the fridge and use it within 24 hours. Throw away any leftovers in the bottle.
