Please note that the Happy Nappy is a snug fit, so if in doubt we would suggest going for the next size up.
Great nappy. Fit was true to size. I ordered a small for a 2 1/2 month old. Very comfortable for baby around the waist, not too tight but nice and snug around the tummy to do it's job well!
What do I use underneath a Happy Nappy? The Happy Nappy reliably protects against leaks into the pool without the need for any other under nappy. However, we do recommend wearing a Nappy Wrap and Liners with the Happy Nappy, to help you with changing and cleaning should an accident occur.
Size up. The obvious thing to do is to size up! If your baby's nappy is leaking at night and certainly if it's happening during nap time, it may be time to get a bigger sized nappy to hold in all that extra wee!
Swim nappies have one main purpose: to prevent faecal matter from entering a pool. Many people do not initially realise that swim nappies do not actually hold urine but this is one thing that they are not designed for.
What is the difference between the Happy Nappy Duo and the Happy Nappy? Both the Happy Nappy and the Duo work in the same way to protect against leaks into the pool. The Happy Nappy Duo has the added benefit of an inbuilt under nappy that helps to keep solids inside. Your swim school may require a double nappy system.
While the nappy size may appear to fit your baby, the amount of pee may have increased with his growth, so the nappy may not be able to absorb the larger amount of urine. For disposable nappies, the bigger the size, the better the absorbency.
Most babies will start in the Newborn size (which also has a cut-out in the front for the umbilical cord) then ultimately spend the majority of their diapering days in size 4, the most popular size on the market.
Nappy size guides
Brands may have different size guides but generally speaking, they work like this: Size 0 (1-2.5kg, 2-5lbs) Size 1 (2 -5kg, 5-11lbs) Size 2 (3-6kg, 7-14lbs)
4 to 5 boxes of Size 1 (based on a 168 pack size; babies will typically be in this size for 3 months, with 6-9 diaper changes per day) 5 boxes of Size 2 (based on a 148 pack size; babies will typically be in this size for 3 months, with with 6-9 diaper changes per day)
Weight brackets in nappies overlap by quite a bit. This is because two babies of the same weight can be a completely different build and height. This can make choosing the best size for your little one seem a little overwhelming. But don't worry, it's more straightforward than you might think.
In general, it's important to change a nappy after each poo, but not necessarily after every wee (more on that below). Regardless, you can certainly anticipate quite a few nappy changes in the first year of your little one's life!
Babies have very delicate skin so their nappy needs to be changed as soon as they wet or poo themselves, otherwise their skin becomes sore and red. Changing your baby's nappy as soon as possible after they've done a wee or poo will help prevent nappy rash.
Happy Nappy™
The New and Improved Happy Nappy by Splash About is a reusable neoprene swim nappy which reliably protects against faecal leaks. Endorsed by parents worldwide and recommended by 90% of UK swim schools, The Happy Nappy is the ideal alternative to disposable swim nappies.
Even though swim diapers and swim pants might hold in some solid feces, they are not leak proof. Swim diapers can delay diarrhea-causing germs, like Cryptosporidium, from leaking into the water for a few minutes, but swim diapers do not keep these germs from contaminating the water.
If you can't comfortably fit two fingers under the waistband of the fastened nappy, it's time for a bigger size. You may need to go up a size if you notice red marks on your baby's tummy or thighs when you remove the nappy. If the nappy isn't fully covering your baby's bottom, choose a bigger size.
Put your baby to bed wearing two nappies (one pull-up nappy over the regular nappy). You may want to use one size bigger for the additional nappy so that it's not too uncomfortable for your baby. Pull-up nappy pants work best as the second layer.
As a general rule of thumb, night time nappy changes are necessary if your baby has soiled the nappy, or it is completely full. A little bit of urine in the nappy is fine, and you can usually wait a bit longer before changing them again.
In many cases blowouts happen because of the wrong size diaper or diapers that aren't fully snug on the baby. It can be hard to ensure a good diaper fit when changing a wriggly baby! Diaper blowouts will happen, so always carry a spare change of clothes for your baby.
They should fasten easily without having to tug them too much. If the tabs meet or overlap in the middle with no problem, the diaper might be too big. On the other hand, if you have to pull to fasten them and they're tight, the diaper is probably too small.
