Diapers
Diapers as a sign of enough milk
How many pee and poop diapers to expect in the first week, and the signs of dehydration that need a call.
You can't see how much milk goes in during a breastfeed, but you can see what comes out. In the first weeks, the number of pee and poop diapers is one of the simplest signs that feeding is going well, alongside weight checks at the pediatrician.
The first week
What the AAP and NHS describe for breastfed newborns:
| Day | Pee diapers | Poop |
|---|---|---|
| Days 1–2 | 2 or 3 in the first 48 hours (NHS) | 1 or 2 a day, black and tarry (AAP) |
| Days 3–4 | Starting to increase | At least 2 a day, turning greenish to yellow (AAP), and from day 4, at least 2 soft yellow poops a day (NHS) |
| Day 5 onwards | At least 6 heavy pee diapers every 24 hours (NHS), or 6 or more by days 5–7, with nearly colorless or pale yellow urine (AAP) | By days 5–7, yellow and loose with small curds, at least 3–4 a day (AAP) |
The two sources count poops a little differently. Both agree that a newborn who is feeding well has several each day by the end of the first week. After the first weeks, poop patterns vary much more from baby to baby.
A tip from the NHS: disposable diapers can hide how wet they are. Pour 2–4 tablespoons of water into a clean diaper to feel what "heavy" is like.
Logging diapers
Chickpea counts a mixed diaper as both pee and poop. A day with few diapers logged may just be a day with few logs: the chart counts only what was logged, so the trend is most useful when every change goes in. Feeds are shown alongside, since fewer feeds and fewer diapers together matter more than either alone.
Signs of dehydration
From the AAP: fewer than six pee diapers a day, a dry mouth, fewer tears than usual when crying, or a sunken soft spot on the head. More serious: peeing only once or twice a day, sunken eyes, being very fussy or unusually sleepy, or cool, discolored hands and feet.
When to call your pediatrician
- Fewer pee diapers than the table above from day 5, or dark urine.
- Poop isn't changing from black toward yellow over the first week, as the table describes.
- Any sign of dehydration from the list above.
- If your baby is very drowsy, hard to wake or not interested in feeding, get urgent help: call 911 (999 in the UK) or go to the emergency department (NHS page on fever in children).
- You're worried about how much your baby is getting: ask early. A lactation consultant can help with nursing.
