Quick answer
Most 11-week-olds take about 4–6 oz (120–180 ml) of formula or expressed breast milk per feed, 5–6 times in 24 hours, for roughly 24–32 oz (720–960 ml) a day. Breastfed babies usually nurse 7–9 times a day. Feeds often get quicker as babies become more efficient. Follow your baby's cues.

How much should an 11-week-old eat?
| Formula | Breast milk | |
|---|---|---|
| Per feed | 4–6 oz (120–180 ml) | 3–5 oz (90–150 ml) per bottle of expressed milk; at the breast, your baby leads |
| Feeds in 24 hours | 5–6 | 7–9 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 11 weeks?
Eleven weeks is often the calm before the 3-month growth spurt. Many babies settle into 5–6 feeds a day if formula-fed, and 7–9 breastfeeds if nursing.
Feeds get faster as babies get stronger. A breastfed baby may finish noticeably sooner than a month ago and still be getting plenty, as long as diapers and weight gain stay on track.
If you're tracking, look at the weekly average instead of single days. A light day followed by a hungry day is typical.
How much formula does an 11-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 5–6 feeds |
|---|---|---|
| 11 lb (5 kg) | About 27.5 oz (825 ml) | 4.5–5.5 oz (135–165 ml) |
| 12 lb (5.4 kg) | About 30 oz (900 ml) | 5–6 oz (150–180 ml) |
| 13 lb (5.9 kg) | About 32 oz (960 ml), the 32 oz ceiling | 5.5–6.5 oz (165–195 ml) |
Sample 11-week-old feeding schedule
| Time | What happens |
|---|---|
| 5:00 am | Milk feed: 4–6 oz (120–180 ml) bottle, or a breastfeed |
| 8:30 am | Milk feed: 4–6 oz (120–180 ml) bottle, or a breastfeed |
| 12:00 pm | Milk feed: 4–6 oz (120–180 ml) bottle, or a breastfeed |
| 3:30 pm | Milk feed: 4–6 oz (120–180 ml) bottle, or a breastfeed |
| 6:30 pm | Milk feed: 4–6 oz (120–180 ml) bottle, or a breastfeed |
| 9:30 pm | Milk feed: 4–6 oz (120–180 ml) bottle, or a breastfeed |
Many 11-week-olds take their biggest bottle first thing in the morning after the longest sleep. Responsive feeding (offering milk when your baby shows hunger cues) matters more than the clock.
What are hunger and fullness cues at 11 weeks?
Hungry
- Hands to mouth and lip smacking, even mid-play
- Turning toward the breast or reaching for the bottle
- Fussing that settles as soon as a feed starts
- Waking earlier than usual from a nap
Full
- Pulls off to look around and doesn't go back
- Pushes the bottle away or closes mouth
- Relaxed hands, happy babbling
- Gets playful or squirmy instead of sucking
What changes next week?
At 12 weeks a growth spurt often shows up, with a few hungrier days.

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 an 11-week-old eat?
About 4–6 oz (120–180 ml) of formula per feed, 5–6 times a day, for roughly 24–32 oz (720–960 ml). Breastfed babies usually nurse 7–9 times in 24 hours.
My breastfed 11-week-old only feeds for about 10 minutes. Is that enough?
Often it is, because older babies are more efficient. Plenty of wet diapers, steady weight gain and a content baby are the signs feeds are working. The AAP lists feeds that are regularly shorter than about 10 minutes as worth checking, so mention it at your next visit if you're unsure.
Should I follow a strict feeding schedule at 11 weeks?
Most guidance, including the CDC and AAP, favors responsive feeding: offer milk when your baby shows hunger cues. A loose daily routine is fine as long as it bends around your baby's appetite.
How do I know my 11-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.
