What to look for when choosing the best swimming nappies
Reusable or disposable?
Swim nappies can either be disposable or reusable and are available at most supermarkets and pharmacies. Some swimwear also has nappies built into them.
Disposable swim nappies
They look like regular nappies and are thrown away after one use. If you opt for these, you may need to take a few more as back up, especially if you're heading to the seaside or going to the beach. Your baby can't wear them for extended periods of time when they are wet as it can cause nappy rash.
Reusable swim nappies
These tend to look like small pants, shorts or part of a swimsuit that can be washed and worn again. They are designed to dry quickly, so if your child has come out of the water, there isn't a risk of nappy rash.
Swim pants are usually worn on top of disposable swim nappies. They're a lovely way of adding extra protection and making potentially boring disposable nappies cuter.
What features to look for in a swim nappy?
Leakage
Swim nappies are designed to contain most stools until you can remove your child from the water and to the toilet. However, loose stools and urine will not be stopped by swim nappies from leaking into the water. Make sure you take your child to the toilet at regular intervals during the swimming session.
Size
Disposable swim nappies are sized in the same way as standard nappies. Make sure you choose a fit that will be secure and snug. You don't want them to be too big or too small as they may restrict your baby's movement or prevent them from fitting into a swim ring.
Adjustable tabs
Parents who tested swim nappies for our Mother&Baby Awards mentioned the swim nappies they preferred had adjustable tabs for babies in between sizes so they could make sure they were more secure.
Cost
If you plan to take your baby swimming regularly, think about the cost of a disposable baby swim nappy compared to a reusable baby swim nappy, as you could spend more over time rather than one investment.

Best reusable swim nappy
Winner of Gold for Best Swimming Product in the Mother&Baby Awards 2021
Splash About has designed the most reliable, reusable baby swim nappy, the Happy Nappy Duo. Fully tested and approved by UK swim schools, it offers maximum protection against faecal leaks due to its distinctive ergonomic design and double layer nappy system. It's technically constructed from malleable neoprene, with contoured panels to cup baby's bottom, innovative fitted gusset and specialist-pressured fabric at the waist and legs to provide a secure, comfortable seal. This form-fitting swim nappy moves as baby moves, but uniquely there's no gaping, regardless of how baby kicks/twists in water.
Features & Reviews Editor Emily Gilbert said: "While our swimming school requires a Happy Nappy to be worn, I would have chosen the Duo regardless as I love that it means I don't have to purchase separate throwaway swim nappies as well, saving me money and helping me do my bit for the environment. Although snug as is necessary, I have no problems getting my son into the Happy Nappy Duo and he seems comfortable wearing it too. The designs are super cute though I'd love to see more 'boy' options available."

Charlie Banana swim nappies are great swimming nappies and potty training pants in one. There is no need to use disposable swim nappies as reusable ones do the job perfectly for the pool or beach. Charlie Banana Swim Diaper & Training pants have a waterproof, outer layer and a soft organic cotton interior lining, which is gentle against your baby's skin. These make ideal training pants when potty training a child because of the trim fit, easy removal and a fine absorbent layer to minimize little accidents!
One reviewer said: "This swim nappy is very easy to use. I really like the pull up style as opposed to Velcro or popper like other reusable swim nappies I have. It makes putting it on a wriggly baby very easy. Because of the drawstring it is also very easy to undo and take off while wet too. The nappy can also be used as training pants so it does have an absorbent part but I didn't find this to be too bulky while in the water which is good."
Pros
- Waist ties are adjustable
- Bright colours are easy to spot (safety reasons)
Cons
- Lack of size options

He also wears swimming shorts which fit perfectly over the swimming nappy as they're not big and bulky like some.

When can babies go swimming?
According to the NHS, 'You can take your baby swimming at any age, both before and after they have been vaccinated. It does not matter if they have not yet completed their course of vaccinations.' So really, the choice is completely yours.
Do swim nappies hold wee?
Many people are surprised to learn that swim nappies aren't designed to hold urine. The materials that make them effective in water also mean they can't contain wee. Otherwise they will be bulky and uncomfortable for your wee ones.
Do swim nappies hold runny poop?
To avoid turning your swim holiday into a mess, always scoop your baby or toddler out of the pool immediately after they poop. Swim nappies, whether disposable or reusable, are mostly made to handle solid poop, meaning runny poop can sneak out from the sides. Even solid poops can only be contained for a short while, so hustle out of the pool pronto and get your child changed ASAP.
Do you put a nappy under a swim nappy?
No, you don't need to wear a regular disposable nappy under a reusable swim nappy. Regular nappies are designed to absorb liquids, which can make them bulky and uncomfortable in the pool. Instead, you can use a disposable swim nappy underneath a reusable swim nappy for added protection.
How many swim nappies for a two week holiday?
If you are planning for a long two-week getaway. Best to travel prepared. You'll want about 20 disposable swim nappies on hand. That's enough for one each day, plus a few extras just in case. If you prefer reusable swim nappies, having three should cover you for the whole trip—you can wash and reuse them as needed.
What do I need to take my baby swimming?
-
Swim nappies
-
A swimming costume or baby wetsuit
-
Your baby's favourite bath toy
-
A soft towel or towelling dressing gown
-
A snack if your baby is weaning. Swimming is hungry work!
-
A baby swim vest
-
A bottle of milk if you're bottle-feeding
-
A changing mat and your changing bag
-
Your own swimsuit and a change of underwear!
How do I wash reusable swim nappies?
So that your reusable swim nappy doesn't lose shape, they should be hand washed in cool water. If your baby has soiled their nappy, then wash it on a gentle cycle in the washing machine.
Baby swimming lessons
Indoor pools have opened again across the UK, and swimming lessons have resumed. If you would like some in-person support when taking your baby swimming, why not see if your pool offers swimming lessons or classes? It's a great way to meet other parents and for your youngster to see other babies in the same situation as them.
There are also plenty of swimming programmes in leisure centres or indoor pools available, especially for babies all around the country. Here are a few programmes to look into:
-
Turtle Tots
-
Water Babies
-
Aquatots
-
Puddle Ducks
-
Little Dippers
