Cuddlies Nappy Size Guide
Choosing the right nappy size is essential for your baby’s comfort.
why the right nappy size matters
✨ No leaks, no worries: A too-small nappy might leak, while one too big can sag and shift.
🛡️ Protects sensitive skin: A proper fit helps prevent rubbing, redness, and nappy rash.
😴 Better sleep: A snug nappy = better overnight absorbency = longer stretches of sleep (for both of you).
🌍 Less waste: Right size = fewer unnecessary changes and less waste - great for the planet and your wallet.

Nappy Size & Fit FAQs
How do I know if my baby’s nappy is the right size?
Check for a snug but comfy fit around the waist and legs. You should be able to slide two fingers under the waistband. If there’s leaking, red marks, or the nappy feels tight, it might be time to size up.
What are the signs it's time to go up a nappy size?
- Frequent leaks or blowouts
- Deep red marks around the waist or thighs
- Tabs that no longer reach comfortably
- Baby hitting the upper end of the weight range
My baby is between two sizes - which one should I choose?
If your baby is in between sizes and you’re noticing leaks or tightness, we recommend sizing up. A slightly roomier fit with strong leg cuffs (like Cuddlies offers!) provides better comfort and absorbency.
Can the wrong nappy size cause nappy rash?
Yes. A too-tight nappy can cause rubbing and trap moisture, while a loose one may lead to leaks and longer exposure to wetness. Cuddlies nappies are made from breathable bamboo and is far superior in its absorbency than others, and designed to reduce irritation with no skin irritants - but the right size helps too!
How fast do babies outgrow nappy sizes?
Every baby grows at their own pace, but here’s a rough guide:
- Newborn to 3 months: Expect to size up at least once
- 3-12 months: Most babies change sizes every 2–3 months
- 1 year+: Changes slow down but still happen as they become more active
Do bigger nappies hold more?
Not always! It’s better to choose the right fit than size up just for extra absorbency. Cuddlies nappies are built with 12+ hour leak protection in every size - so no need to compromise fit for performance.
