Happy Nappy™ Swimsuit
The Happy Nappy™ Swimsuit is Splash About’s award-winning one-piece baby swimsuit with a built-in reusable swim diaper. Designed especially for babies and toddlers, it combines adorable swimwear with the trusted leak protection of our original Happy Nappy™.
The integrated neoprene swim diaper features specialist ribbed seals around the waist and thighs to help securely contain fecal leaks in the pool. Its contoured design fits comfortably around your baby’s bottom without restricting movement, giving them the freedom to kick, splash, and enjoy the water.
Baby Swimsuit with Built-In Swim Diaper
With the Happy Nappy™ already built into the swimsuit, there’s no need to wear a separate Happy Nappy™. The soft, stretchy swimsuit provides comfortable coverage, while the integrated reusable swim diaper delivers the reliable protection parents and swim schools expect from Splash About.
Perfect for baby swim lessons, indoor pools, vacations, and family swimming, the Happy Nappy™ Swimsuit is a practical alternative to buying separate baby swimwear and a reusable swim diaper.
Available in a range of exclusive Splash About prints, our baby swimsuits with built-in swim diapers combine comfort, style, and trusted leak protection in one easy-to-wear design
Happy Nappy™ Swimsuit FAQs
The Happy Nappy™ component of the Happy Nappy Swimsuit™ requires a correct fit for complete solid leak protection. Since babies vary in size, it's essential to measure your baby accurately and consult the size guide to ensure you purchase the right size.
Measure your baby while lying flat and not immediately after a feed. Take measurements around their tummy, across the belly button, and at the fullest part of their thigh. When worn, there should be enough space to fit a finger comfortably around the edges of the seal, with no red marks.
As with disposable swim diapers, the Happy Nappy™ within the Happy Nappy™ Swimsuit does not hold in urine. It is designed to allow water to pass in and out of the diaper to prevent it from becoming waterlogged. However, it is incredibly reliable in containing solids.
No. The Happy Nappy™ is designed to be used without any other swim diaper
underneath and can be worn in this way for general swimming, inflatable pools or the ocean. However, some organised swimming classes require a double diaper system; in such cases, you will also need to purchase a Silver-Lining or Cotton diaper Wrap to wear underneath. This system can also make changing and washing a soiled
Happy Nappy™ easier.
To keep your Happy Nappy™ Swimsuit in good condition, we recommend hand washing in cool water and drying away from direct sunlight. However, we understand that soiled diapers may occasionally require machine washing. If you need to machine wash, please do so at 85°F using a non-biological detergent. Please note that frequent machine washing may affect the longevity of the product.
