Splash About Happy Nappy, Under The Sea, 3-6 Months

We recently started baby swimming classes with our 7-month-old, and the Splash About Happy Nappy has been a total game-changer. It’s comfortable, secure, and does exactly what it promises—no leaks! I was a little nervous about pool accidents, but this nappy gives real peace of mind. It fits snugly around the legs and waist without being too tight, and our baby doesn’t seem bothered by it at all.We pair it with a reusable swim nappy liner for easy cleanup, and it works beautifully. The quality is excellent—it’s stretchy, soft, and easy to get on and off, even with a wriggly baby. Plus, the designs are adorable, which is a bonus!It’s also great knowing it’s approved by most baby swim schools, so we didn’t have to worry about meeting any class requirements.Highly recommend for any parent getting into baby swimming—this nappy takes away the stress and lets you just enjoy the fun!

My son has been swimming since he was just 12 weeks old — he’s now 3, and we still keep coming back to the Happy Nappy by Splash About. It’s honestly the one swim essential I’ve never had to second-guess.From baby swim classes to toddler splash sessions, this nappy has never let us down. It fits snugly without being uncomfortable, and I love the peace of mind knowing there won’t be any accidents in the pool. The material is soft yet durable, and the waistband and leg cuffs give a secure seal that holds up even through lots of wriggling and movement.We’ve gone through a few sizes over the years, and every one has been great. Easy to rinse out, dries quickly, and the designs are always cute — a small bonus, but it makes it fun for him to pick which one to wear!If you’re thinking of starting swimming with your little one or just need a reliable swim nappy that actually works, this is it. Couldn’t recommend it more highly!

fab swim pants. fit is good and pretty pattern. arrived as expected

Quite big for a 3month old but perfect to put a disposable swimming nappy underneathBaby tested on his first swim and no poo leakage 👍

My son is nearly 6 months old and the 6-12months nappy fits perfectly (he is on the 50th centile). Nappy is good quality, no leaks and when he wore it with a swin suit he was nice and warm in the water. Will buy again when he grows out of this one. Also the colour is really nice.

We love the happy nappy range. We have bought a swimsuit and separate happy nappy pants in every size for our little one whilst she has been attending Water Babies swimming lessons. The pants can be worn under swimming costumes or as their own individual piece and it fits all of the requirements for ‘double nappies’ as set by many pools. The pants don’t provide as much coverage as the swimsuits, but my daughter has been perfectly warm in hydrotherapy pools. It’s also been nice to use with a separate rash vest.The pink colour on these pants was as lovely as pictured and the quality of the material is really excellent. I love the bold colours, which make my little one even more visible in the water. They’re a little stiff to get on, there isn’t much stretch, so it’s obvious when you need to size up, but it gives reassurance that no little accidents could possibly leak. The inner lining is black, so there’s no risk of any unpleasant staining either. The sizes are reasonably generous though; my 26 month old is still in her 12-24 month pair.They do require handwashing, which is a little bit of a downside - people with young children don’t have much time for this sort of thing, but the colour and pants themselves have lasted really well, probably as a result. Hand-wash cycle in the washing machine has been fine fortunately!

Great quality, sizing up is definitely worth it so it’s not too tight on baby’s legs. For reference my 5&1/2 month old is 9kg and 1-2 years was the recommended size for his legs and waist. No messy accidents happened and I felt reassured that baby was warm and nothing would leak.

These are ideal (and a must) for swimming and make sure to keep any toilet needs at bay!I would recommend getting a bigger size - to gauge the sizes: my son is of the 40th percentile in our area (London) he is currently 4 months old and the 3-6 that we purchased a month ago is now getting quite tight to put on. I reckon when he is 5 months he’ll be in the 6 months version. So I would say if your baby is a month off, get the bigger one.If you regularly attend swimming lessons like puddle ducks or waterbabies, you can ask for their recommendation too as they’re quite helpful with that.

I’m so glad I found this reusable swim diaper! It’s incredibly well-made and fits my toddler perfectly. The material is soft yet durable, and it does an excellent job of preventing leaks, giving me peace of mind during swim lessons. The adjustable fit ensures comfort as my little one grows, and it’s so easy to wash and reuse. What’s even better is that this is the only brand allowed at my toddler’s swim facility, so I can rest assured that it meets their strict guidelines. It’s been a great investment and a must-have for anyone looking for a reliable, eco-friendly option for swim time. Highly recommend!

Swim diaper is really well made. I love the way it fits my 16 month old (got him a 2-3 yo size because he is 30lbs and huge). The poop stays in and does not 'stick' to the fabric which makes cleaning super easy. It also doesn't sqeeze his chunky thighs leaving marks so it looks more comfortable on him than a typical swim diaper. I wish I bought one for my first child because these seem really durable and I bet I could have used it for more than just my son. I definitely will pass this swim diaper on to future family/friends children.

Too small!! My grandson is 12 months old… very average size for his age. These are tight all over but especially on his legs.

great quality, as with other splash about nappy products

Wir mussten die erste hose leider zurückschicken da sie sehr klein ausfallen wir hatten 3-6 M bestellt (unser Sohn war zu dem Zeitpunkt 3 1/2M) und die war viel viel zu eng. Jetzt haben wir 6-12 M und die sitzt perfekt und es ist noch Luft zum mitwachsen . Davon abgesehen ist die Hose super
