Baby nappies explained: how often + what’s normal in the early days
Quick answer
Choosing the right nappy can help keep your baby comfortable while reducing leaks and skin irritation. This guide explains different nappy types, sizing and practical tips for everyday nappy changes.
Nappies are one of the easiest ways to tell if your baby is getting enough milk — but no one really explains what you’re actually looking for.
In the first few days, everything changes quickly. The colour, how often they go, even how heavy they feel.
This is a simple way to make sense of it without overthinking it.
What’s normal in the first week
In the first few days, nappies build up gradually as your baby starts feeding more.
Day 1–2: very small amounts
Day 3–4: more wet nappies + changing poo colour
Day 5+: more regular output
That shift from dark, sticky poo to yellow is a good sign things are moving as expected.

Wet nappies are usually the biggest clue that feeding is going well.
You’ll see them increase over the first few days, then by around day 5 you’re looking for about 5–6+ a day.
It doesn’t need to be exact — it’s more about things moving in the right direction.
If nappies stay low, it can sometimes mean baby isn’t getting quite enough milk yet.
What helps: Products I actually used
Changing bag with built-in mat. Small, organised and actually used daily
Baby water wipes. Simple, reliable option
Nappy caddy (keeps everything in one place)
Poo colour and frequency
Poo can look a bit alarming at first, but most of the changes are completely normal.
It usually goes like this:
dark/black (first couple of days)
green/brown
yellow, soft
From around day 5, you’ll usually see:
at least 2 poos a day
softer, yellow stools
That’s a sign feeding is starting to settle in.
When to pay a bit more attention
Most variation is normal, but it’s worth noticing the overall pattern.
Keep an eye on:
very few wet nappies
no change in poo colour over time
baby still seeming unsettled after feeds
These can sometimes link back to feeding.

Final thought
The early stage feels confusing because it’s not structured yet.
It’s inconsistent, a bit all over the place, and very baby-led — but that’s exactly what helps everything settle later on.
This isn’t professional advice — just a simple breakdown of what I’ve found helpful.
Most of this is easier to understand when you can see it clearly.

FAQs
How many nappies does a newborn actually go through a day?
Usually way more than people expect at first. In the newborn stage, 8–12 nappies a day can be completely normal because they feed so often. It normally starts calming down a bit after the first couple of months.
How often should I change a baby’s nappy?
Most babies need changing every 2–4 hours during the day, plus whenever they poo. You don’t have to panic over every tiny wee straight away, but leaving poo sitting too long is usually what causes irritation fastest.
Is it normal for nappies to feel constantly full overnight?
Yes — especially once babies start sleeping longer stretches. Overnight nappies can feel ridiculously heavy by morning, which is why a lot of parents eventually switch to nighttime nappies for extra absorbency.
How do I know if a nappy is too small?
Leaks, blowouts, red marks around the legs, or tabs that barely close are usually the biggest signs. Sometimes moving up a size fixes the problem immediately even if the weight guide says they still technically fit.
Are expensive nappies actually better?
Honestly, not always. Some babies do perfectly fine in supermarket nappies, while others leak through expensive ones constantly. It usually comes down to your baby’s shape, skin sensitivity, and how heavy they wee rather than the price.
