How much should a 7-week-old eat?
Last reviewed November 2026 against AAP, CDC, NHS and WHO guidance · Sources
Quick answer
Most 7-week-olds take about 4–5 oz (120–150 ml) of formula or expressed breast milk per feed, 6–7 times in 24 hours, for roughly 24–32 oz (720–960 ml) a day. Breastfed babies usually nurse 7–10 times a day. Many babies this age take bigger, less frequent bottles. Follow your baby's cues.

How much should a 7-week-old eat?
| Formula | Breast milk | |
|---|---|---|
| Per feed | 4–5 oz (120–150 ml) | 3–4 oz (90–120 ml) per bottle of expressed milk; at the breast, your baby leads |
| Feeds in 24 hours | 6–7 | 7–10 breastfeeds |
| Daily total | 24–32 oz (720–960 ml) | About 750 ml (25 oz) |
| Typical gap | Every 3–4 hours | Every 2–4 hours |
What's happening at 7 weeks?
Seven weeks often feels steadier. Bottles of 4–5 oz (120–150 ml) are common for formula-fed babies, with around 6–7 feeds in 24 hours.
Some babies start a longer first stretch of sleep at night. Night feeds are still normal and expected.
If someone else gives bottles while you rest, a shared log keeps everyone on the same page about when the last feed was and how much went in.
How much formula does a 7-week-old need by weight?
The AAP's rule of thumb uses weight instead of age: about 2½ oz of formula per pound of body weight a day, and no more than about 32 oz (960 ml). In the UK, the NHS uses a similar guide of 150–200 ml per kg a day after the first week. Both are rough checks, not targets.
| Baby's weight | Per day (AAP, 2½ oz per lb) | Per feed at 6–7 feeds |
|---|---|---|
| 9.5 lb (4.3 kg) | About 24 oz (720 ml) | 3.5–4 oz (105–120 ml) |
| 10.5 lb (4.8 kg) | About 26.5 oz (795 ml) | 4–4.5 oz (120–135 ml) |
| 11.5 lb (5.2 kg) | About 29 oz (870 ml) | 4–5 oz (120–150 ml) |
Sample 7-week-old feeding schedule
| Time | What happens |
|---|---|
| 3:00 am | Milk feed: 4–5 oz (120–150 ml) bottle, or a breastfeed |
| 6:30 am | Milk feed: 4–5 oz (120–150 ml) bottle, or a breastfeed |
| 10:00 am | Milk feed: 4–5 oz (120–150 ml) bottle, or a breastfeed |
| 1:30 pm | Milk feed: 4–5 oz (120–150 ml) bottle, or a breastfeed |
| 4:30 pm | Milk feed: 4–5 oz (120–150 ml) bottle, or a breastfeed |
| 7:00 pm | Milk feed: 4–5 oz (120–150 ml) bottle, or a breastfeed |
| 10:00 pm | Milk feed: 4–5 oz (120–150 ml) bottle, or a breastfeed |
Seven feeds with one longer night stretch (10 pm to 3 am here) is a common shape at seven weeks. Responsive feeding (offering milk when your baby shows hunger cues) matters more than the clock.
What are hunger and fullness cues at 7 weeks?
Hungry
- Rooting toward your chest or the bottle
- Fists to mouth and sucking sounds
- Puckering or smacking lips, clenched hands
- Fussing that builds; crying comes later
Full
- Closes mouth or pushes the nipple out with the tongue
- Turns head away from the breast or bottle
- Relaxed, open hands
- Fidgety or easily distracted once the edge is off
What changes next week?
At two months (week 8) many formula-fed babies take about 4–5 oz (120–150 ml) and may be moving toward fewer night feeds.

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 much should a 7-week-old eat?
Most 7-week-olds take about 4–5 oz (120–150 ml) of formula per feed, 6–7 times a day, for roughly 24–32 oz (720–960 ml). Breastfed babies usually nurse 7–10 times in 24 hours.
My 7-week-old only takes 2–3 oz from a bottle of breast milk. Is that enough?
It can be. Breastfed babies often take smaller bottles than formula charts suggest, because breast milk intake stays around 750 ml (about 25 oz) a day from 1 to 6 months (HSE). Wet diapers and weight gain are the better guide.
My 7-week-old finishes a bottle in a few minutes. Is that a problem?
Very fast feeds can mean the nipple flow is quick, which makes it easy to overfeed. Try a slower-flow nipple and paced bottle feeding so your baby has time to show they're full.
How do I know my 7-week-old is getting enough milk?
Look at diapers and growth more than ounces. Six or more wet diapers a day, regular poops, a baby who seems content after most feeds, and steady weight gain at checkups are the signs the AAP points to. If any of these slip, call your pediatrician.
