How much does a newborn eat in the first days?
The first days are measured in milliliters, not ounces. Ireland's HSE lists colostrum feeds of a few drops to 5 ml on day 1, 5–15 ml on day 2 and 15–30 ml on day 3. The AAP says formula-fed babies often take about ½ oz (15 ml) per feed for the first day or two, then 1–2 oz (30–60 ml).
For day-by-day detail, including diapers and poop colors, start with newborn day 1.
Does a breastfed baby follow the same chart?
Not quite. Breastfed babies nurse on cue, usually 8–12 times a day in the early weeks (CDC). Once breastfeeding is established, daily intake stays fairly flat: the HSE says babies aged 1 to 6 months who only have breast milk take about 750 ml (25 oz) a day.
That's why bottles of expressed milk often stay around 3–5 oz (90–150 ml) for months, while formula bottles keep growing. See formula vs breast milk amounts for the full comparison.
How do I work out amounts by weight?
Two rules of thumb are widely used. The AAP suggests about 2½ oz of formula per pound of body weight per day, and no more than about 32 oz. The NHS suggests 150–200 ml per kg per day after the first week, until about 6 months.
For a 10 lb (4.5 kg) baby that's about 25 oz (750 ml) a day by the AAP rule and 680–910 ml by the NHS range. The baby feeding calculator does this for your baby.
How should I use a feeding chart?
- Treat every number as a range. Some feeds are big, some are snacks.
- Watch your baby, not the bottle: hunger and fullness cues come first.
- Look at daily totals and diapers over a few days, not one feed.
- Bring a few days of notes to checkups. Growth on your pediatrician's chart is the real test.
When to call your pediatrician
- A rectal temperature of 100.4°F (38°C) or higher in a baby 3 months or younger. The AAP says to call right away, even if your baby seems otherwise well.
- Fewer wet diapers than expected for their age (fewer than 6 a day from about day 5), or dark yellow urine.
- Very sleepy and hard to wake for feeds, floppy, or unusually quiet.
- Refusing feeds, or feeding poorly several times in a row.
- Signs of dehydration: dry mouth, no tears, or a sunken soft spot on the head.
- Forceful or green vomiting, or vomiting after most feeds.
- Red, black (after the first meconium poops) or white/pale gray poop.
- Yellow skin or eyes that spread or deepen, or any yellow color in the first 24 hours.
- Trouble breathing, blue or gray lips, or your baby is limp or very hard to wake: call 911 (or your local emergency number) now.
If something feels wrong, trust that feeling and call. You never need a reason beyond worry.
Questions parents ask
How many ounces should a newborn drink?
About ½ oz (15 ml) per feed on days 1 and 2, then 1–2 oz (30–60 ml) for the rest of the first week, according to the AAP. By the end of the first month, most formula-fed babies take 3–4 oz (90–120 ml) per feed.
What is the maximum amount of formula a baby should have?
The AAP says babies generally don't need more than about 32 oz (960 ml) of formula in 24 hours. If your baby regularly wants more, talk with your pediatrician.
How much breast milk does a baby need a day?
From about 1 to 6 months, babies who only have breast milk take about 750 ml (25 oz) a day, according to Ireland's HSE. Unlike formula, that amount stays fairly steady across those months.
How many times a day should a newborn eat?
About 8 to 12 times in 24 hours, according to the CDC, for both breastfed and formula-fed newborns. Feeds space out as babies grow, to about 4 to 5 a day by 6 months for formula-fed babies (AAP).
