Newborn day 6: diapers, poop and feeding
Last reviewed November 2026 against AAP, CDC, NHS and WHO guidance · Sources
Quick answer
On day 6, expect 6 or more wet diapers and 3 or more poops (mustard-yellow). Most newborns feed 8–12 or more times in 24 hours, and formula-fed babies take about 1.5–2 oz (45–60 ml) per feed. Yellow, seedy poops are a good sign that milk is getting through. Every baby is different, so watch diapers and cues.

How much does a 6-day-old eat?
Feeds are settling into a pattern of 8–12 in 24 hours, often every 1–3 hours for breastfed babies (CDC). Some babies bunch feeds in the evening.
If you're formula feeding, bottles of about 1.5–2 oz (45–60 ml) are typical this week. Follow your baby's cues rather than finishing every bottle.
How many diapers should a 6-day-old have?
6 or more wet diapers, with pale yellow or nearly clear urine (AAP). Breastfed poops are mustard-yellow, loose and seedy, often after feeds. Formula-fed poops are tan to yellow and a bit firmer.
See every day side by side in wet diapers by day and the baby poop color guide.
What else is normal on day 6?
- If you've been home a few days, a weight check this week tells you how feeding is going.
- Start noticing early hunger cues (rooting, hands to mouth) so you can feed before crying.
What happens on day 7?
Day 7 rounds out the first week, with 6 or more wet diapers and yellow poops as the new normal.

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
What color should a 6-day-old's poop be?
Mustard yellow for most breastfed babies and yellow-tan for formula-fed babies (AAP). Shades of green or brown can also be normal. Black after the first days, red, or white/pale gray poop is worth a call.
How often should a 6-day-old eat?
About 8 to 12 times in 24 hours (CDC): roughly every 1 to 3 hours for breastfed babies and every 2 to 3 hours for formula-fed babies. Some feeds bunch together in the evening.
How many wet diapers should a 6-day-old have?
Expect 6 or more wet diapers in 24 hours on day 6, plus 3 or more poops that are mustard-yellow. Fewer wet diapers than that, or dark urine, is a reason to call your pediatrician.
