Breastfeeding
How to tell if your baby is getting enough breast milk
Last reviewed November 2026 against AAP, CDC, NHS and WHO guidance · Sources
Quick answer
A breastfed baby is likely getting enough when they have 6 or more wet diapers a day from about day 5, at least 3–4 yellow poops a day by days 5–7, audible swallowing during feeds, content stretches between feeds, and are back to birth weight by about 2 weeks. These AAP and NHS signs matter more than ounces.

How many diapers mean my baby is getting enough?
| Days | Wet diapers | Poops |
|---|---|---|
| Days 1–2 | 1–3 (NHS: 2–3 in the first 48 hours) | 1–2, black and tarry |
| Days 3–4 | 3–4 or more | 2 or more, greenish to yellow |
| Days 5–7 | 6 or more, pale urine | 3–4 or more, yellow and loose |
| Week 2 on | 6 or more | Often 4+ in the first month |
What does a good breastfeed look and sound like?
- A few quick sucks, then long, rhythmic sucks and swallows with short pauses (NHS)
- Cheeks stay rounded, and you can hear or see swallowing once milk is in
- Your baby comes off the breast on their own and seems content
- Breasts feel softer after the feed
- 8–12 feeds in 24 hours in the early weeks (AAP, CDC)
What weight gain is normal for a breastfed baby?
The AAP says a healthy newborn loses no more than about 8–10% of birth weight in the first few days, starts gaining around day 5, and is usually back to birth weight by about 2 weeks (almost all by 3 weeks). After that, the AAP lists gaining less than roughly 5–7 oz a week as a warning sign.
Which signs are not reliable?
- How much you can pump. Babies usually get more milk than a pump does.
- How full your breasts feel after the early weeks. Softer breasts are normal once supply settles.
- Frequent feeding on its own. Cluster feeding is normal; diapers and weight tell the story.
How can tracking help?
A simple log of feeds and diapers turns "I think it's fine" into numbers you can share: "9 feeds, 7 wet, 4 dirty yesterday." Pediatricians and lactation consultants use exactly these counts. See how to track baby feeding.
When to call your pediatrician
- Fewer wet diapers than expected for your baby's age, or dark yellow urine.
- Still black or dark green poop on day 5, or fewer than 4 stools a day after day 7 (AAP).
- Milk hasn't come in by day 5, or breasts stay full and hard after feeds.
- Not back to birth weight by about 2 weeks.
- Feeds regularly shorter than about 10 minutes or longer than about 50 minutes, or your baby seems hungry after most feeds.
- Very sleepy, hard to wake for feeds, or skipping feeds.
- 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.
- 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 do I know my breastfed baby is full?
Full babies usually relax their hands, slow their sucking, come off the breast on their own and look content or sleepy (CDC, NHS). Over the day, 6 or more wet diapers and steady weight gain confirm it.
How many wet diapers should a breastfed baby have?
From about day 5, the NHS says at least 6 wet diapers every 24 hours, and the AAP 6 or more with pale yellow urine by days 5 to 7. In the first 48 hours, 2 to 3 is typical.
Can I tell how much milk my baby gets from pumping?
Not reliably. Most babies remove milk more efficiently than a pump. Diapers and weight gain are far better signs of intake than pumped volume.
Is it normal for a breastfed baby to feed every hour?
For stretches of the day, yes. The CDC notes some babies feed as often as every hour at times, especially during cluster feeding. Over 24 hours, 8 to 12 feeds is typical in the early weeks.
