  • If your child isn’t potty trained, they should wear swim diapers when entering the pool or ocean. 
  • A swim diaper differs from a regular diaper and is designed not to swell in the water. 
  • The best swim diaper contains solids, not liquids; you shouldn’t use it for other activities besides water play. 

I’ll never forget the first time I realized I needed swim diapers—and it was when I had none. I took my son to a splash park and let him frolic in his regular diaper. Let’s just say the diaper had seen better days when he finished playing. 

Swimming diapers hold in poop (not pee, sorry!) while your little one is living their best life at the swimming pool. However, swim diapers don’t swell like regular diapers, which helps prevent what happened to my son. 

You can choose a disposable or reusable swim diaper, depending on your needs. While reusable swim diapers are eco-friendly, their disposable counterparts offer convenience. 

The best swim diapers are perfect for a day at the swimming pool, beach, or just a dip in the kiddie pool. Happy swimming, little ones!

What Are Swim Diapers?

Cute little baby swimming to father in a pool,.

Swim diapers work for children who aren’t potty trained and want to go in the pool or ocean. While swim diapers don’t absorb liquids, they keep solid poops inside instead of making their way into the water. 

Regular Diapers Vs. Swim Diapers

Unlike regular diapers, swim diapers don’t have an absorbent layer and are mainly designed to keep in fecal matter, not liquids, so it doesn’t enter the pool water. 

If your child poops while you’re at the pool, you should still change them quickly to avoid a potential accident. Although, we know to do that with a regular diaper, too. 

According to the Centers for Disease Control and Prevention, while most germs are killed by chlorine, there is still the chance of recreational water illnesses11. Centers for Disease Control and Prevention. Poop in the Pool. Centers for Disease Control and Prevention. 2022. https://www.cdc.gov/healthywater/swimming/aquatics-professionals/fecalresponse.html (RWI) caused by fecal matter in public pools. 

Another benefit of swim diapers is you typically don’t need to put a bathing suit on top because they generally are made of soft mesh and waterproof fabric. 

Things to Consider Before Buying a Swim Diaper

While grabbing something off the shelf is always convenient, knowing what you should consider before buying swim diapers is helpful. Here’s a list of our top things to consider before purchasing a swim diaper. 

Size

Similar to regular diapers, swim diapers come in specific sizes, so finding the appropriate size for an accurate fit is essential. While you want to ensure no gaps for leakage, you also don’t want the diaper too tight where it’s uncomfortable. 

Typically, swim diapers offer a snug fit but aren’t tight on your baby’s legs. In addition, swim diapers aren’t meant for newborns who have loose stools. That’s not to say you can’t take young babies in the pool, but you should be cautious. 

Disposable Vs. Reusable Swim Diapers 

You’ll find the two types of swim diapers, reusable and disposable—but is one better?

There are pros and cons of reusable and disposable, and I always considered where I was going when I packed. 

For example, disposable diapers are ideal if you’re doing a one-day trip to the beach. At the same time, reusable diapers are handy on a trip where you don’t want to go through a whole pack of disposable swim diapers. 

The best reusable swim diapers are gentle on your baby’s bum while keeping solid waste out of the pool. On the other hand, the best disposable swim diaper makes it easy to change your baby and get on the road. 

However, reusable swim diapers are environmentally friendly and cost-effective over time, which is helpful if you’re in the water frequently. 

Materials and Comfort

If your little one is swimming, you want them to feel comfortable. Like regular diapers, you don’t want swim diapers too tight, where they feel restrictive. 

Swim diapers typically have a waterproof outer layer and an extra layer of protection on the interior. Your baby’s swim diaper should fit snugly but not dig into their legs or waist. 

Designs and Styles

There are various swim diaper designs and styles, regardless of whether you choose disposable or reusable swim diapers. However, finding a stylish swim diaper removes the need for a bathing suit. Who knew picking out a swim diaper could be a fashion event?

FAQs 

Are swim diapers necessary for all water activities or only for swimming pools?

You should put your baby in a swim diaper for all water activities since you don’t want them pooping, even in a kiddie pool. If your little one frequently plays with water, investing in reusable swim diapers is probably a good idea. 

In addition, if your child takes swimming lessons and isn’t potty trained, they should wear a swim diaper in the water. 

How often should I change my child’s swim diaper during a beach or pool outing?

You should change your child’s swim diaper anytime they poop. Otherwise, your little one can stay in the swim diaper until you are finished swimming. However, it’s best to check your little one’s swim diaper every 30–60 minutes to ensure it’s clean.
