How Do I Fit My Adjustable Nappy on My Newborn?
Fitting an adjustable cloth nappy on a newborn can feel intimidating at first — especially when everything about your baby feels tiny and delicate. The good news is that modern adjustable nappies are designed to be flexible, forgiving, and easy to customise once you understand a few basics.
Here’s a simple, step-by-step guide to getting a comfortable, leak-free fit for your newborn.
What Is an Adjustable Cloth Nappy?
Adjustable (or “one-size”) cloth nappies use snap settings or Velcro to change the nappy’s height and width as your baby grows.
For newborns, the goal is to:
- Shorten the rise (front-to-back length)
- Create a snug but gentle seal around the legs
- Keep absorbency trim and comfortable
Step 1: Adjust the Rise Snaps First
Before putting the nappy on your baby, adjust the front rise snaps.
For newborns:
- Fasten the rise snaps to their smallest setting
- This shortens the nappy so it sits properly under the belly button
If the nappy is too long, it can gape at the legs or push up uncomfortably.
Step 2: Choose the Right Absorbency
Newborns urinate frequently but in smaller amounts.
Use:
- A single newborn-appropriate insert
- Avoid bulky multi-layer inserts at this stage
Less bulk helps achieve a better fit and keeps your baby comfortable.
Step 3: Position the Nappy Correctly
Lay your baby down and:
- Slide the back of the nappy under their bottom
- Bring the front up just under the belly button
- For babies with an umbilical stump, fold the top edge down slightly to avoid rubbing
A good newborn fit sits low and snug — not high and tight.
Step 4: Secure the Waist
Fasten the waist snaps or Velcro so the nappy is:
- Snug enough to stay in place
- Loose enough to fit two fingers comfortably at the waist
Avoid over-tightening — tight nappies don’t prevent leaks and can cause marks.
Step 5: Check the Leg Fit
This is where leaks usually happen.
Make sure:
- The leg elastic sits in the underwear line (where underwear would sit)
- There are no gaps at the thighs
- The fabric is tucked neatly into the leg crease
You should see a gentle seal, not red marks.
Step 6: Do a Final Fit Check
Before dressing your baby, check:
- Rise snaps are secure
- Inserts are fully inside the nappy
- No absorbent material is sticking out
- The nappy looks symmetrical
A well-fitted nappy should look snug and comfortable, not bulky or saggy.
Common Newborn Fit Issues (and Easy Fixes)
Leaks at the legs
→ Tighten the leg area slightly or reduce insert bulk
Red marks
→ Loosen the waist or legs; marks should fade quickly
Nappy looks huge
→ Normal for newborns — bulk reduces as baby grows
Gaps around thighs
→ Check rise snaps and leg tuck
How Often Should I Change My Newborn’s Nappy?
Newborns usually need changing every 2–3 hours, or as soon as they soil the nappy. Frequent changes help:
- Prevent leaks
- Reduce nappy rash
- Keep your baby comfortable

When Might Adjustable Nappies Not Fit Yet?
Some very small or premature babies may not fit adjustable nappies straight away. In those cases:
- Newborn-specific cloth nappies
- Or short-term disposable use
can bridge the gap until your baby grows.
This is normal and doesn’t mean adjustable nappies won’t work later.
Final Thoughts
Fitting an adjustable nappy on a newborn is a skill — and like all new parenting skills, it gets easier with practice.
Once you’ve found the right snap settings and absorbency, cloth nappy changes become second nature. Be gentle with yourself — and your baby — as you learn together.
