Can cloth diapers be used as swim diapers?

Whether it’s a day at the local splash pad, swimming lessons, or a family holiday at the beach, swim diapers get lots of use year round for most little ones.

But what if you don’t have a swim diaper? Can you just use a cloth diaper cover as a makeshift swim diaper?

Not really; but maybe.

To explain, when it comes to swimming in a pool (any size), lake, ocean, or other body of water, you’re going to need a proper swim diaper, for reasons I’ll explain below.  But for an impromptu trip to the local splash pad or run through a sprinkler, where baby is staying on land, a diaper cover can do the trick in a pinch if you make some special adjustments.

Why do I need a swim diaper, why can’t I use regular diapers in the pool?

Regular diapers are designed to hold a lot of liquid, and hold solids in too, it’s their job. Swim diapers on the other hand are designed to hold solid waste inside but to let the water out. This is true of both reusable swim diapers and disposable swim diapers.

Wait! Does all this mean the pee will escape?

Yes, because swim diapers are designed not to hold water, but to let it out easily, they will let urine out. So if you’ve ever questioned whether or not public pools really do get peed in, now you know for sure (thank goodness for chlorine)!

Swim diapers will also let out urine when a little one pees in them out of water, so make sure you change them back into a regular diaper as soon as they are done playing in the water.

I always think of my friend who suddenly asked, “Why is my lap warm?” while holding her little one as he was enjoying a snack after some fun at the splash park.

A note about EBF poop: If your exclusively breast feeding (EBF), you’ll know that EBF poops can sometimes get runny. If your little’s poops are way more liquid than they are anything else, take that into consideration when heading out for some water play. A very watery poop may leak through swim diaper fabric, so be carefully watching for activity down there if you think this could happen.

Why swim diapers let the water out

Swim diapers are made to let the water out both for safety and because that’s how they work properly.

Safety

If your baby’s diaper were to swell with water while they are playing at the beach or swimming in the pool, they would be weighed down. And we’re not talking a little bit, but a lot.

The blog All About Cloth Diapers did some testing on how much cloth diapers could hold, which you can read here. In their experiments some fitted diapers were able to hold 30 oz of water. That’s nearly 2 lbs! Don’t forget the average weight of a 6-month-old is just 16.1 pounds for girls and 17.5 pounds for boys.

Two pounds is a lot for such a little one and is of course dangerous and could be even fatal in a swimming pool.

Function

Swim diapers also let the water out so that when you take baby out of the water the poop stays in the diaper. To really understand how this works, let’s talk about what happens when you try to use a cloth diaper cover in the pool.

Why Cloth Diaper Covers Can’t do the same thing in the pool

Cloth diaper covers are great at keeping messes in on dry land, but diaper cover has a waterproof coating on it to ensure that your floor, clothes, couch and lap stay dry. In the pool, a cloth diaper cover will slowly fill up with water around the waist and legs, and hold it there.  When you take your little one out of the pool, all that water can’t escape anywhere but through the leg openings, taking the poop right along with it.

Not only does no one want to swim with a Baby Ruth in the water, but many public swimming pools have specific requirements for swimming diapers that state the diaper can not be absorbent and must be able to contain solid waste.

It should be pretty obvious why, poop in the pool means E. coli, C. difficile, Giardia and other bacteria that can make and other bacteria that can make others sick. Often when a poop incident happens in a swimming pool the pool must be closed and treated, which means lost revenue and unhappy people.

What the Pool does to Cloth Diapers

It’s also important to note that swimming pools have a lot of chlorine in them (remember all that pee).  This chlorine will ruin the waterproofing on your diaper cover if exposed repeatedly. Since many diaper covers cost more than a good swim diaper, wearing a cloth diaper cover in the pool may not even make sense financially.

So when is using a cloth diaper cover as a swim diaper ok?  

While diapers made for swimming are necessary for the pool, in my opinion (and I’m probably going to catch some flack for this), yes, you can use a cloth diaper cover as a swim diaper in a pinch at the splash pad or when playing with a sprinkler. What you can not use is an absorbent cloth diaper or cloth diaper inserts.

Put another way, you can ONLY use a cloth diaper cover, with no absorbent layers attached. This means no all-in-one diapers, all-in-two inserts, pocket diaper inserts, fitted diapers, prefold diapers, or flat diapers in the water, for reasons we’ll get into below.

I feel cloth diaper covers without absorbency are ok to use in these situations for two reasons:

  1. Your little one is not going to be submerged so their diaper won’t fill with water that will need to flow out of the legs. Poop should be contained inside the cover well; and
  2. Splash pads and sprinklers use potable (drinkable) water in most cases, which is not heavily chlorinated and so it shouldn’t do any damage to the cover chemically.

How to use a cloth diaper cover as a swim diaper on the fly

If you decide to use a cloth diaper cover as a swim diaper on land, the first thing you’ll need to do is remove all of the absorbent inserts, prefolds, etc.

Next, you’ll want to readjust the cover’s rise and waist adjustments as once you take out the absorbent layers the fit will have changed. You want to make sure that the diaper is good and snug around the legs and waist so that no solids can get out of it. A swim diaper is designed to fit firmly to the body so that even when water is involved, there’s no chance of less-than-solid fecal matter from escaping.

Why can’t I use absorbent diapers at the splash pad?

As explained above, absorbent diapers will not only absorb urine, but water as well. Wearing an absorbent diaper in the water will weigh baby down significantly, which is always a safety risk even on land where throwing your little one’s balance off can mean lots of falls, scrapes and bruises.

What’s my washable swim diaper recommendation?

My absolute favorite swim diaper is by AppleCheeks. Though they have three sizes available, I bought a size two, and it fit my daughter from about 4 or 5 months old until potty training because the fabric was so movable and it adjusted so well. I could actually still put it on her if I wanted, but she’s now daytime potty trained (and was potty trained fairly late).

I also found the fabric to be the softest and most breathable compared to other swim diapers I tested. It’s actually made of a mesh material, which lets the water in and out, but it’s so trim and snug (which it can be because it’s so soft) nothing is getting out of there.

AppleCheeks has also recently released matching UV protection swim shirts as well, which were not available when I was shopping for swim diapers (I’m a little bitter about that).

AppleCheeks swim diapers are available at one of my recommended local cloth diaper retailers Cloth Diaper Kids, here, or also directly through Amazon here.

I can’t recommend them higher!

How many swim diapers will you need?

It’s of course going to depend on how often your going to take your little one swimming, but I recommend having at least two swim diapers on hand. You don’t want to have to leave the pool five minutes in because there was a poop and you don’t have a clean diaper. You also won’t want to put that swim diaper that smells like pee back on baby after your lunch break, and you won’t want to be stuck if you get behind on laundry. Two swim is I think the minimum, with three giving you a nice buffer to play with during those busy summer months.

Again, adjust that if you go to the pool a lot, are planning a beach vacation away from a washing machine, or if it’s rare for you to do water activities.
