Nappies or nappy pants?
Here’s how to choose.

Both keep your baby dry, comfortable, and protected. The difference comes down to fit, flexibility, and where your little one is at. Here’s a simple guide to help you find the right match.

Treasures Nappies
Classic Choice

Nappies

The trusted choice from day one. Tab-fastening nappies give you precise control over fit, making them ideal for newborns and younger babies who need frequent changes. Easy to adjust, easy to remove, and reassuringly familiar for those early weeks and months. The secure tab fastening also means you can check the fit and readjust without needing to remove the nappy entirely, which is a small but welcome win during those frequent newborn changes.

Best for: Newborn to around 9 months
Treasures Nappy Pants
Built for Movers

Nappy Pants

Built for babies on the move. Nappy pants pull up and down just like real underwear, making changes faster and less disruptive as your baby becomes more active. No tabs, no fuss, just a snug comfortable fit that moves with them. Many parents also find nappy pants a natural, positive step toward toilet training, since they look and feel like the underwear their child is working toward.

Best for: 9 months onwards, active babies, and toilet training

Ready to make
the switch?

Most families move to nappy pants when their baby starts pulling themselves up, rolling, or becomes harder to keep still during changes. There’s no set age - you’ll know when the time feels right.

Many parents use nappies overnight and nappy pants during the day. Whatever works for your family is the right answer.

Fit Tips

  • Weight is the best guide - age ranges are approximate as every baby grows differently.
  • The waistband should sit snugly but you should be able to slide two fingers underneath.
  • Leg cuffs should lie flat against your baby’s skin with no gaps.
  • If you’re between sizes, size up for a more comfortable fit overnight.
  • Red marks on your baby’s skin mean the nappy is too small - time to go up a size.
  • For nappy pants, they should fit like underwear - snug but not tight, with the waistband at the natural waist.

Weight ranges may overlap. If your baby is between sizes, we recommend sizing up for a better fit. Pack counts may vary.
