Changing a nappy is one of the most repetitive parts of everyday life with a small child. But how often should you actually change a nappy? What do you do if it leaks? And how many nappies does a child need? Here is a calm, practical guide that sorts out the questions — so you feel more confident and less stressed.
From Emelie: The basic rule is simpler than you might think: change after every poo, and otherwise roughly every three hours. The rest is detail you pick up along the way. When I was a new parent myself I thought it was a science — in reality the routine settled into place on its own. Read what you need, skip the rest.
How often should you change a nappy?
As a new parent, it can feel overwhelming how many nappy changes a small child actually needs. A good rule of thumb is to change after every poo and, as a routine, roughly every three hours (ideally around mealtimes). Newborns need the most changes; the older the child gets, the fewer.
Does your child have a red or irritated bottom? Then change more often — as soon as the nappy feels damp, rather than waiting. Keeping the skin dry both eases the discomfort and prevents it from getting worse. There is more on care in our guide to a red bottom and nappy rash.
It can sound like a lot at first, but as your child grows and you find your routines it gets easier. Night changes can often be phased out over time — prioritise sleep and only change if your child has done a poo.
How often to change a nappy — by age
Approximate guide values. Every child is unique, so treat this as a starting point, not a rule:
| Age | Roughly how often | Changes per day |
|---|---|---|
| Newborn (0–1 month) | every 2–3 hours + after every poo | 8–12 |
| 1–5 months | every 2–3 hours | 6–8 |
| 6–12 months | every 3–4 hours | 5–6 |
| 1 year and older | every 3–4 hours | 4–6 |
| Night | as needed, otherwise in the morning | 0–1 |
Night-time is where the questions most often come up as a parent — but it is usually simpler than you think. Most people only change as needed, or if the child has done a poo; otherwise in the morning. A nappy with extra absorbency usually lasts through the night.
A tip: choose a nappy with a stay-dry surface against the skin at night. The stay-dry layer wicks moisture away so it feels dry against the skin even when the nappy has filled up — so your child can sleep a little more peacefully without being woken by the feeling of being wet. Our overnight nappies offer that choice in the included insert (a stay-dry side and a bamboo side) — simply turn the stay-dry side towards the skin at night. There is more on dry nights in the overnight nappy guide.
Do you have to change a nappy the moment your child has weed?
Poo nappies should be changed as quickly as possible to avoid skin irritation. Wee nappies usually last a few hours, but it is still good to change regularly to keep the skin dry.
How many nappies does a child need?
It varies a lot with age and how often the nappy is changed. Newborns may need up to 10 changes a day, while older children might manage on 5–6. You will find more on changes for a newborn in our guide.
If you plan to use cloth nappies full time, you need at least around 24 to have enough changes between washes. How many of each (cover, insert) depends on the system you choose — we sort that out in our buying guide. If you want an easy way to get started, a starter kit is a good option.
Are there differences in nappy changing between a girl and a boy?
With cloth nappies you can adjust the absorbency to your child’s needs. A rule of thumb is to place more absorbency at the front for boys and more in the middle for girls.
When you change a boy, it is good to make sure the penis points downwards, so it does not leak at the top when he wees. For girls, it is important to wipe from front to back to avoid bacteria in the urethra.
Also be prepared for your child to take the chance to wee just as the nappy comes off — especially boys. Keep a cloth wipe or towel to hand.
If the nappy leaks
A leaking nappy rarely means it is full — most often it is the fit or the amount of absorbency that needs looking at. With cloth nappies: make sure the elastic sits snugly around the legs (it should fit like a pair of knickers), and add an extra insert if the nappy is often full at the change. Change a little more often too if needed.
The full troubleshooting — day and night, step by step — is in our guide to why the nappy leaks and how to fix it.
How to tell it is time to change
Over time you sense the rhythm automatically, but at first it helps to know what to look for. Change when:
- Your child has done a poo — always as soon as you notice it.
- The nappy feels heavy or looks swollen — then it has soaked up quite a lot.
- It has been about three hours since the last change — a good routine check even if the nappy does not feel full.
- The skin is red or irritated — change as soon as it feels damp.
- Your child shows discomfort or grizzles for no obvious reason — sometimes a wet nappy is the answer.
With cloth nappies you quickly learn to feel for it. Many disposable nappies have a wetness indicator — an added dye that reacts with the liquid and gives a line on the outside of the nappy. With a cloth nappy you simply feel on the outside of the nappy, with your hand: if the cloth nappy is completely soft and fluffy it is dry, while a slightly firmer, stiffer feel means there is wee in it. No added dye is needed — just touch, and after a few days it becomes second nature.
And the reverse: a cloth nappy with a stay-dry surface can feel dry against the skin even though it has filled up somewhat, so trust the weight and the clock too — not just how dry it feels.
In summary
Changing a nappy is a central part of parenting, but it is simpler than it sounds: change after every poo and otherwise roughly every three hours, a little more often for the littlest ones and less often as your child grows. And remember — every child is unique. Be patient, try things out and find the routine that suits you best.
Frequently asked questions about nappy changes
How often should you change a nappy?
A good rule of thumb is to change after every meal, often roughly every three hours — and always after a poo. See the age table above for guide values by age.
Do you have to change straight away when your child has weed?
Poo nappies are changed as quickly as possible. Wee nappies last a few hours, but change regularly to keep the skin dry.
How often should you change a nappy at night?
Most people only change as needed, or if the child has done a poo — otherwise in the morning. A nappy with extra absorbency (or a dedicated overnight nappy) usually lasts through the night.
How many nappies does a child need?
Newborns may need up to 10 changes a day, older children 5–6. For cloth nappies full time: reckon on at least around 24.
Why does the nappy leak?
Most often it is about fit or too little absorbency — rarely about the nappy being completely full. See our guide to leaks for the full rundown.
