When it’s time to take your little one for a swim, not just any nappy will do. Regular nappies are absorbent and will quickly become heavy and waterlogged. That’s why waterproof swim nappies are a must-have for beach days, swimming lessons, or any water activity.
But what exactly are waterproof swim nappies? Do they really work? And is there such a thing as a swim nappy that holds pee? If you’re asking these questions, you’re not alone. In this post, we’ll explain how waterproof nappies function, what to look for, and why reusable options are becoming the preferred choice for many parents.
Do Waterproof Nappies Work?
Yes, waterproof nappies absolutely work but only for what they’re designed to do. Unlike traditional nappies, which absorb liquids, swim nappies are designed to contain solid waste only. This is an important distinction and one that surprises many parents.
Waterproof swim nappies are typically made with:
- A waterproof outer layer that helps contain solids
- A breathable, soft inner lining to keep baby comfortable
- Snug leg and waist openings to prevent leaks without restricting movement
As long as the fit is correct, waterproof swim nappies are effective at containing solid accidents, which helps maintain hygiene in public or shared swimming spaces. However, they’re not absorbent and that’s by design.
Is There a Swim Nappy That Holds Pee?
This is one of the most commonly asked questions, and the answer is: no, swim nappies are not designed to hold urine.
Swim nappies, whether reusable or disposable, allow urine to pass through them. This is because an absorbent nappy would soak up pool or seawater and become extremely heavy, bulky, and uncomfortable for the baby. It could even pose a safety risk if it weighs the child down in the water.
Allowing urine to pass through may sound odd at first, but it’s standard across all swim nappies. In public pools, hygiene standards account for this, and the water is treated to handle small amounts of urine. The key function of the nappy is to prevent solid waste from entering the water, not to hold liquids.
What Are the Best Leakproof Nappies for Swimming?
When searching for the best waterproof or leakproof nappies for swimming, you’ll want to focus on the following features:
-
Waterproof Outer Fabric
A quality swim nappy will have a durable, waterproof outer shell that helps contain solids and prevents leaks. -
Breathable Inner Layer
Look for a soft, non-absorbent mesh lining that’s gentle on your child’s skin and dries quickly. -
Secure and Adjustable Fit
The nappy should fit snugly around the legs and waist to contain messes, without causing discomfort. Adjustable snaps or stretchy materials help create a better seal as your baby grows. -
Reusable Design
Reusable swim nappies are not only more cost-effective in the long run, but they’re also better for the environment than single-use alternatives. -
Quick-Drying and Easy to Clean
A swim nappy should be easy to rinse out and wash between uses.
