Newborn day 11: diapers, poop and feeding
Last reviewed November 2026 against AAP, CDC, NHS and WHO guidance · Sources
Quick answer
On day 11, expect 6 or more wet diapers and 3–4 or more poops (yellow, sometimes green or brown). Most newborns feed 8–12 or more times in 24 hours, and formula-fed babies take about 2–3 oz (60–90 ml) per feed. A few green poops are usually fine. Every baby is different, so watch diapers and cues.

How much does a 11-day-old eat?
A pattern is starting to show: 2–3 oz (60–90 ml) bottles or 8–12 breastfeeds a day. Some babies push one longer stretch at night.
Paced bottle feeding (holding the bottle more horizontal and pausing often) lets bottle-fed babies set their own pace and is handy for combo-fed babies too.
How many diapers should a 11-day-old have?
Expect 6 or more wet diapers and regular yellow poops. The AAP says shades of yellow, brown and even green are all acceptable after meconium.
See every day side by side in wet diapers by day and the baby poop color guide.
What else is normal on day 11?
- If your baby seems hungry after most feeds, the AAP suggests a weight check and a look at latch and positioning.
What happens on day 12?
Day 12 is usually more of the same. Keep an eye out for the 2–3 week growth spurt.

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 the day of life (see the table above), or dark yellow urine.
- No meconium (black, sticky poop) in the first 48 hours, or still black or dark green poop on day 5.
- Pink or brick-red staining in the diaper that keeps showing up after the first few days, or blood in the urine.
- Not back to birth weight by about 2 weeks, or your baby seems hungry after nearly every feed.
- Breastfeeding parent: milk hasn't come in by day 5, or breasts stay hard and full after feeds.
- Very sleepy and hard to wake for feeds, floppy, or unusually quiet.
- 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
Is green poop normal at 11 days?
Usually. The AAP says shades of yellow, brown and green are all within normal after meconium. Red, black or white/pale gray poop is worth calling about.
Can an 11-day-old sleep 4 hours?
Sometimes, but in the first few weeks the AAP suggests waking a baby who sleeps longer than 4 to 5 hours and offering a feed, especially until weight is back to birth weight.
How many wet diapers should a 11-day-old have?
Expect 6 or more wet diapers in 24 hours on day 11, plus 3–4 or more poops that are yellow, sometimes green or brown. Fewer wet diapers than that, or dark urine, is a reason to call your pediatrician.
