How many wet nappies should a newborn have?
The day-by-day count that tells you whether your baby is feeding enough — plus what counts as "wet", how dirty nappies change colour in the first week, and the signs of dehydration to act on.
Nappies are the only measurement of feeding you can actually make at home. You can't see how much milk went in, but you can see what comes out — and in the first weeks, that count is the single most useful number you have.
The day-by-day chart
An easy way to remember the first week: the number of wet nappies roughly matches the day of life, up to about six.
| Age | Wet nappies | Dirty nappies | Stool colour |
|---|---|---|---|
| Day 1 | At least 1 | At least 1 | Black, sticky (meconium) |
| Day 2 | At least 2 | 1–2 | Still dark, less sticky |
| Day 3 | At least 3 | At least 2 | Greenish-brown, transitional |
| Day 4 | At least 4 | At least 2 | Greenish-yellow |
| Day 5 | At least 5 | At least 3 | Yellow, seedy, loose |
| Day 6 onwards | 6 or more | 3 or more | Mustard yellow, seedy |
| 6 weeks onwards | 6 or more | Varies widely | Yellow to brown |
Six or more heavy wet nappies a day, from day five onwards, is the number to hold on to. Urine should be pale and close to odourless.
What actually counts as a "wet" nappy
Modern disposable nappies are extremely good at hiding urine, which makes this genuinely hard to judge. Three ways to tell:
- Weight. A wet nappy feels noticeably heavier. If you're unsure, pour 3 tablespoons (about 45 ml) of water into a dry nappy and feel it — that's roughly what one wet nappy weighs.
- The wetness indicator. Most brands print a stripe that changes colour. Use it.
- Cloth nappies make this obvious, which is one underrated reason some parents use them in the first fortnight.
Orange or pink-red crystals in the nappy — sometimes called brick dust — are urate crystals. They're common and harmless in the first two or three days. After day three they suggest the baby isn't getting enough milk, and that's worth a same-day call to your paediatrician.
Dirty nappies: how often is normal?
Stool frequency varies enormously after the first month, and that variation is one of the most misread things in early parenting.
Breastfed babies. In the first six weeks, at least three yellow stools a day. After six weeks, this can change dramatically — some breastfed babies go once every few days, and a fully breastfed baby going up to a week without a stool can still be entirely normal, provided the stool is soft when it arrives and the baby is comfortable and feeding well. Breast milk is efficiently absorbed; there is genuinely little waste.
Formula-fed babies. Usually more predictable — typically one to four a day, firmer and more tan or brown than mustard yellow.
The thing to watch is not frequency but consistency. Hard, pellet-like stools that are difficult to pass mean constipation regardless of how often they come. Soft stool every five days does not.
Nobody remembers nappy counts by eveningAraia logs a wet or dirty nappy in one tap — from the home screen, a lock-screen widget, or just by asking Siri — and shows the running daily total against what's expected for your baby's age.

Dehydration in a newborn moves faster than in an older child. These are the signs that mean call your paediatrician today:
- Fewer than 6 wet nappies a day after day five, or no wet nappy for 6+ hours in a newborn
- Dark yellow, strong-smelling urine
- Urate (brick dust) crystals after day three
- A dry mouth, or crying without tears in a baby over three weeks
- A sunken soft spot (fontanelle) on the top of the head
- Unusual sleepiness, or a baby who is difficult to rouse for feeds
- Skin that stays tented when gently pinched
Any of the last three, or a baby who seems floppy or unwell, is a reason to go to hospital rather than wait for a call back.

This guide is general information for Indian parents, written from published paediatric guidance (IAP, WHO, AAP). It is not medical advice and cannot account for your baby specifically. Anything that worries you — feeding, breathing, fever, weight, a rash — is a call to your paediatrician, not a search. In an emergency, go to a hospital.
