Awards

The Splash About Happy Nappy won Gold for Best Swimming Product in the Mother&Baby Awards 2025. The spectacular range of designs on offer and the high quality materials really impressed the mum testers who used it with their children - read on to find out exactly what they had to say!
Testing the Splash About Happy Nappy

Our parent testers absolutely loved the Happy Nappy! Having tested the product with their own child, one mum told us that "this product is brilliant," going on to say, "I packed it flat, and it's nice and light." Another tester agreed with this assessment of the weight, saying, "My 3-year-old spent 3 hours wearing it in a water park. He was very happy and comfortable using it in the water without the normal heavy diaper."
"My daughter is a year and a half and can wriggle when getting a nappy on but it went on so quickly there were no issues," revealed one of our testers. The fit was complimented by many - another mum told us that "our baby seems comfortable in the nappy and isn’t unsettled while wearing it in and out of the water." A great-looking nappy is useless if the child won't wear it, so we're glad to hear it's easy to get little ones to wear.
Speaking of aesthetics, the designs were a real hit, too - one mum said, "The beautiful design with water animals made my baby so excited and happy to wear," presumably referring to the Under the Sea option. Another pleased parent told us that "it is beautifully designed (we have the crocodile design), and my toddler couldn’t wait to wear it." It sounds like both parents and children love all the different options.
A nappy is no good if it's going to leak, and thankfully, the Happy Nappy seems to deliver on its leak-proof promise. "We have used the nappy a few times and haven’t experienced any leakages in the pool," revealed a happy tester. Another thrilled tester had an overall excellent experience, telling us that "everyone complimented my son on the jazzy design of his nappy. He looked stylish and the nappy worked for containing any leaks."

"Our little boy goes swimming every week, and the Happy Nappy is so easy to use, and I know using it, he is comfy, and we don’t have any accidents in the pool," revealed one of our testing team members. A different parent told us that "it looked very comfortable on my daughter and it was easy enough to get on," giving the nappy another point in favour of the softness of materials and comfort of the design.
Final verdict
Overall, parents were thrilled, not just with the striking designs but also with the fit, effectiveness, and comfort of the Splash About Happy Nappy. "To the touch, it felt like a very high-quality product. The material was a lovely feeling - it washed perfectly and looked like new after the wash," said one mum, summing up the nappy perfectly. We'd definitely recommend this product if you want to take your little one swimming and feel secure against any leaks!
