When you’ve just brought your little one home, it’s easy to find yourself counting everything — feeds, sleeps and every nappy change. One question that comes up again and again is: How many wet nappies should a newborn have? And does a dirty nappy with poo count as a wet nappy too?
Wet nappies are a simple way to check whether your bub is getting enough milk, but it’s not always clear what counts — especially if the nappy only feels slightly damp or also contains poo.
Modern nappies are highly absorbent, so wetness can be easy to miss. Knowing what to look for can make tracking your newborn’s output much simpler.
How Many Wet Nappies Should a Newborn Have Each Day?
During the first few days, your newborn’s wet nappies will usually increase day by day as their milk intake grows.

Does Poop Count as a Wet Nappy?
This is an easy one to get caught out by — especially when you’re changing nappies half asleep at 3 am!
Poo on its own doesn’t count as a wet nappy. When we talk about a “wet nappy”, we mean your bub has done a wee.
So:
💧 Wee only? Count it as a wet nappy.
💩 Poo only? Don’t count it as a wet nappy.
💧💩 Wee and poo together? Yep, count it as a wet nappy.
How Wet Is Wet Enough?
How wet is actually “wet”? Does the nappy need to feel heavy? What if there’s only a little bit of wee?
The good news is, a wet nappy doesn’t need to be soaked or feel really heavy to count. Even a small wee counts.
Modern nappies absorb urine very quickly, so you might not always be able to feel much moisture when you pick the nappy up. That doesn’t mean your bub hasn’t done a proper wee.
A few simple things can help you tell:
- The wetness indicator has changed colour – if your nappy has a wetness line, this is an easy sign that your bub has done a wee.
- The nappy feels a little heavier than a fresh one – it doesn’t need to feel full or bulky.
- The inside feels damp or you can see that the absorbent area has changed – even a small amount of urine can be absorbed quickly.
- Still not sure? Weigh it. If you really want to put a number on it, weigh a completely dry nappy first, then weigh the used nappy afterwards. The difference in weight gives you an idea of how much liquid has been absorbed.
If your newborn suddenly has much fewer wet nappies than usual, isn’t feeding well, is unusually sleepy or difficult to wake, or you simply feel that something isn’t right, it’s always okay to contact your midwife, child health nurse or GP.
When Should You Be Concerned About Dehydration?
Most parents worry about missing something, especially during the newborn stage.
You may want to seek advice if you notice:
Much fewer wet nappies than usual, especially if the change continues
- Very dark or strong-smelling wee
- A dry or sticky mouth
- Poor feeding or suddenly refusing feeds
- Your baby is unusually sleepy, difficult to wake, or less responsive than normal
- Your baby seems unusually tired, weak or unsettled
If something just doesn’t feel right, trust your instincts. You know your bub best. If you’re worried about dehydration or your newborn’s feeding and wet nappies, speak with your midwife, child health nurse or GP for advice.
