Quick Answer: Newborns typically go through 8–12 nappies per day in the first few weeks — roughly one every 2–3 hours. This drops to 6–8 per day by 2–3 months as feeding spaces out. Stock around 70–84 nappies per week for a newborn, and don’t bulk-buy too far ahead since babies outgrow sizes quickly.
The Numbers by Age
| Age | Nappies per day | Notes |
|—|—|—|
| 0–4 weeks | 8–12 | Every 2–3 hours, including nights |
| 1–3 months | 6–10 | Feeding stretches slightly |
| 3–6 months | 6–8 | Longer sleep stretches help |
| 6–12 months | 5–7 | More predictable patterns |
These are averages — some newborns hit 14 on a heavy day, others manage on 7. What’s normal for your baby matters more than the average.
How Many Nappies to Stock
For the first month, plan on roughly 300 nappies (10/day × 30 days). Practical buying advice:
- Don’t overstock newborn size. Many babies skip straight past it — buy one large pack, not a year’s supply
- Size up early is fine. A slightly big nappy beats a too-small one that leaks
- Keep receipts. Most supermarkets exchange unopened packs for the next size
A rough first-year total is around 2,500–3,000 nappies — which is why the cost adds up.
The Cost in the UK
- Supermarket own-brand: ~10–13p per nappy → £250–£390/year
- Branded (Pampers etc.): ~18–25p per nappy → £450–£750/year
- Eco/biodegradable: ~20–35p per nappy → £500–£1,000/year
- Reusable cloth nappies: ~£200–£400 upfront for a full set, then minimal ongoing cost
Own-brand nappies from Aldi, Lidl, Tesco, and Sainsbury’s consistently score well in parent surveys — the premium is often marketing, not performance.
Wet vs Dirty: What’s Normal
In the first week, output ramps up as feeding establishes:
- Day 1–2: 1–2 wet nappies, dark meconium stools
- Day 3–4: 3–4 wet, stools transitioning to greenish
- Day 5+: 6+ heavy wet nappies daily, yellow seedy stools (breastfed)
After day 5, fewer than 6 wet nappies in 24 hours can signal feeding issues — mention it to your midwife. The [NHS guidance on newborn nappies](https://www.nhs.uk/conditions/baby/caring-for-a-newborn/) covers what’s normal.
Reducing Nappy Changes (Slightly)
You can’t — and shouldn’t — reduce changes below what hygiene requires. But you can:
- Change before feeds at night so baby settles faster after
- Use the right size — leaks often mean size up, not more changes
- Barrier cream at each change prevents nappy rash, which makes babies fussier about changes
Cloth vs Disposable: The Honest Maths
Cloth nappies need changing just as often (8–12/day for newborns), so you’ll want 20–25 in rotation to allow for washing and drying time. The environmental case is nuanced — cloth wins if washed at 40–60°C in full loads and line-dried; tumble-drying narrows the gap considerably.
FAQs
How many newborn nappies do I need per week?
70–84 for the first few weeks (10–12 per day). This drops to around 50–60 per week by 3 months.
What size nappy for a newborn?
Size 0 or 1 (up to 5kg). But if your baby is born over 4kg, you may go straight to size 1 — don’t stockpile size 0.
How often should I change a newborn’s nappy at night?
Every 2–3 hours, or with each night feed. Don’t let a wet nappy sit — newborn skin is very sensitive.
Is 15 nappies a day too many?
Unusual but not necessarily worrying if baby is feeding well and gaining weight. Mention it to your health visitor if it persists.
When do babies drop to fewer nappies?
Gradually from around 2–3 months as stomach capacity grows and night sleep stretches lengthen.
