Newborns typically eat small amounts frequently, with feeding amounts and frequency increasing as they grow.
How Much Should Newborns Eat?
- In the first few days after birth, newborns usually consume about ½ to 1 ounce (15–30 milliliters) per feeding, gradually increasing to 1 to 2 ounces (30–60 milliliters) by the end of the first week
- By 2 weeks old, babies often take 2 to 3 ounces (60–90 milliliters) per feeding, with about 8 feedings in 24 hours
- Around 1 month, typical feeding amounts are about 3 to 4 ounces (90–120 milliliters) per feeding
- At 2 months, babies may drink 4 to 5 ounces (120–150 milliliters) every 3 to 4 hours
- By 4 to 6 months, feeding amounts increase to about 4 to 8 ounces (120–230 milliliters) per feeding, depending on frequency
- Overall daily intake for formula-fed babies is roughly 2.5 ounces of formula per pound of body weight per day, with a maximum of about 32 ounces in 24 hours
How Often Should Newborns Eat?
- Newborns generally feed every 2 to 3 hours, totaling 8 to 12 feedings per day
- Feeding on demand is recommended, responding to hunger cues such as rooting, sucking on hands, or fussiness
- During growth spurts (e.g., around 7–14 days, 3–6 weeks, 4 months, and 6 months), babies may seem hungrier and require more frequent or larger feedings
- In the first few weeks, it may be necessary to wake the baby to feed if they sleep more than 4 to 5 hours at a stretch
Summary
Newborns start with small, frequent feedings of about ½ to 1 ounce, increasing to about 2 to 3 ounces by two weeks, and 3 to 5 ounces by one to two months. Feeding every 2 to 3 hours (8–12 times daily) is typical, with amounts adjusted based on the baby's hunger cues and growth. Formula-fed babies generally consume about 2.5 ounces per pound of body weight daily, up to about 32 ounces total. Feeding on demand and watching for signs of fullness or hunger ensures proper nutrition and growth. This guidance applies to both breastfed and formula-fed infants, although breastfed babies may feed more frequently with smaller amounts per feeding
