How to Pick the Perfect Night Nappy for Your Baby

The Quick Answer
Think of it like this: Is your baby a regular wetter or a super soaker?

- Heavy wetters need our Heavy Wetter Fitted Nappy

What Makes Them Different?
Mighty Minky Night Nappy - For Average Wetters
This is our "just right" night nappy. It's like sleeping on a cloud but secretly works hard to keep everything dry until morning.
What makes it special:
- Super soft minky fabric on the outside (so cozy!)
- Stay-dry fleece on the inside that pulls wetness away from baby's skin
- Gentle elastic that won't leave red marks on those chunky thighs
- Built-in waterproof layer - no extra cover needed
- Easy pocket opening to stuff your insert
- Comes with our special inserts that dries faster than other night inserts
Size range: Fits babies from 3.5kg to 19kg (about 8 pounds to 42 pounds)
Best for: Babies who wet a normal amount overnight, families who want an easy all-in-one solution
Heavy Wetter Fitted Nappy - For Power Wetters
This is the superhero of night nappies. If your baby treats their nappy like a swimming pool, this is your answer.
What makes it special:
- Made from super absorbent bamboo and organic cotton (60% bamboo, 30% organic cotton, 10% polyester)
- Athletic wicking jersey lining keeps baby's skin dry
- Up to 18 layers of thirsty material in the wet zone
- Can hold up to 600ml of liquid (that's more than 2 cups!)
- Comes with 2 inserts you can fold different ways
- Side snaps let you adjust the fit perfectly for chunky or skinny babies
Size range: Fits babies from 5kg to 18kg (about 11 pounds to 40 pounds)
Important: This nappy needs a separate waterproof cover (like a wool cover or PUL cover) to keep clothes and sheets dry
Best for: Heavy wetters, overnight feeders, toddlers, babies who sleep 12+ hours

How to Know If Your Baby is a Heavy Wetter
You might have a heavy wetter if:
✓ You're changing wet pyjamas every morning
✓ The nappy feels really heavy when you take it off
✓ Regular night nappies leak, even with boosters
✓ Your baby feeds a lot overnight
✓ Your baby sleeps 12+ hours straight
✓ You've tried everything else and still get leaks
What You Need to Know Before Buying
For the Mighty Minky:
Pros:
- Ready to use right out of the box
- No extra cover needed (saves money!)
- Less bulky than fitted nappies
- Dries faster
- Perfect for most babies
- Easy for caregivers and partners to use
For the Heavy Wetter Fitted:
Pros:
- Maximum absorbency - seriously powerful
- Gentle on sensitive skin
- Breathable material reduces rashes
- Can customise absorbency by folding inserts different ways
- Lasts through the longest nights
- Works as a bulletproof daytime nappy too
Things to know:
- You must buy a waterproof cover separately (we love wool covers for nighttime!)
- Takes longer to dry because there's more material
- Bulkier fit (but that's because it holds so much!)
- Two-step system (fitted + cover) takes practice
Real Parent Reviews
About the Mighty Minky:
"It's such a pleasure putting this nappy on my baby at night, it's so soft it's like putting on a cloud! Even with all the layers it just seems so comfy and not a single leak." - Happy Mum
About the Heavy Wetter Fitted:
"My 6 month old had been waking up at 5am every morning with nappy leaks. Thank goodness we found this overnight nappy! We are all definitely enjoying the extra hour or so of sleep!" - Shannen M.
Getting the Best Results
For Both Nappies:
- Get the fit right - The nappy should be snug but not tight. Check the leg holes and waist.
- Pre-wash before first use - New nappies need 3-4 washes to reach full absorbency
- Point everything down - Make sure the wet zone is positioned where your baby needs it
- Change within 12 hours - Even the best nappy has limits!
Mighty Minky Tips:
- Fold your Inserts to put extra layers where your baby needs them most
- For boys, add more layers at the front
- For girls, focus on the middle section
- Can add a hemp booster for extra protection if needed
Heavy Wetter Fitted Tips:
- Fold the snake inserts to create up to 12 layers in the wet zone
- Place one insert in front and one in back for full coverage
- Make sure your waterproof cover completely covers the fitted nappy
- Wool covers work amazingly well with these - they breathe and wick moisture
Can You Use Both?
Yes! Many families keep both types in their stash:
- Use the Mighty Minky for regular nights and lighter wetters
- Keep the Heavy Wetter Fitted for growth spurts, teething nights, or when baby is drinking more
- Start with the Mighty Minky and upgrade to the Fitted if needed
Which One Should You Buy First?
Start with the Mighty Minky if:
- This is your first time trying cloth night nappies
- Your baby is an average wetter
- You want something easy and quick to use
- You prefer less bulk
- You're on a tighter budget
Go straight to the Heavy Wetter Fitted if:
- You already know your baby is a super soaker
- You're currently using disposables at night because cloth keeps leaking
- Your baby sleeps 12+ hours
- You've tried other night nappies and they didn't work
- You don't mind the extra drying time and bulk
Still Not Sure?
That's okay! Here's what we recommend:
- Try a night nappy bundle - Get one of each style to test
- Start with the Mighty Minky - It works for most babies and you can always upgrade
- Join our Facebook community - Other parents can share what worked for their heavy wetters
- Contact us - We're happy to help you figure out which nappy is right based on your baby's needs
The Bottom Line
Both nappies are amazing at what they do. The Mighty Minky is your everyday superhero that keeps most babies dry with less fuss. The Heavy Wetter Fitted is your specialized tool for extreme situations that need extreme absorbency.
Most families love the Mighty Minky. But if you're dealing with morning leaks and soggy sheets despite using the Mighty Minky with boosters, it's time to graduate to the Heavy Wetter Fitted.
Either way, you're making a great choice for your baby's comfort and our planet.
