Inflatable Floaties Only

Our Swim Diapers are designed to contain poop of all kinds to ensure that you, your baby, and your unicorn-shaped floaty are the only ones bobbing around in the pool.

Cute Prints 👌, Stains👎

The soft, inner mesh lining of your swim diaper charcoal coloured - so no stains! Even though your baby had blueberries for breakfast.

Saves your money and your sanity.

Not only does this diaper give you a better fit than disposable swimmers, it can be washed and reused. Saving the environment, your money, and your beach day.

Nervous about taking the plunge (see what I did there?) on reusable swim diapers?

Asking yourself, “Why would I buy a diaper that won’t even hold in pee?”

Have you seen those soggy disposable swim diapers? They are unsanitary and pointless as they absorb water and makes your baby waddle around like a penguin. Does your swimwear hold on to moisture? Obviously not. Our Swim Diapers allow moisture to pass and only holds back solids. If you are scared that your child is going to pee in the pool, then I have news for you - everybody pees in the pool (present company excluded). A swim diaper’s only job is to hold back poop and our diaper does that exceedingly well!!

Because there is one thing that is certain in parenting...

And it’s that “poop happens.”

“What are the odds that my baby will poop while we are swimming?”, you may say. Turns out that, much like the ‘Hunger Games,’ when it comes to poop, the odds are never in your favour. Trust us. And when you are in the pool, your “poop happens” moment can easily become EVERYONE’S “poop happens” moment. And that’s not cool.

Your babies are growing…

Our Swim Diaper grows with them…

Our swim diaper has adjustable snap settings on the waist and rise, that will allow it to fit your little one from 10-40lbs. You can even share our swim diapers between siblings even if they are different ages. And the best part is, almost all our prints are gender neutral so you don’t have to worry even if you keep them for your next one!

A beach day with kids involved is never going to be stress-free, but a wicked awesome swim diaper like ours can at least take the stress of seeing this face off your plate.

We have a lot more to say about this stuff but our web designer believes there is such a thing as “too many” funny GIFs (pfft), so we put it on our blog instead.

Newbie Guide

Our wonderful leader, Captain Poopypants - AKA Mohammed (Chief Everything Officer) - has spent a lot of time researching and working to find the top materials to make good products that are affordable for every family. Here is a quick rundown of what our diaper covers and inserts are made of! Covers- Outer layer is PUL and the inner layer is a dark mesh lining. The ingenious dark lining will hide any unfortunate stains.
When you were deciding whether or not to take the plunge (see what I did there?) on reusable swim diapers, you had doubts. You asked yourself, “Why would I buy a diaper that won’t even hold in pee? What are the odds that my baby will poop while we are swimming?” Turns out that, much like the ‘Hunger Games,’ when it comes to poop, the odds are never in your favour. But even on the off chance you don’t feel like this is enough, it can also be used as a diaper cover in a pinch. Simply add the liners of your choice for absorbency.
The swim diapers can be washed along side your cloth diapers using your regular wash routine.. Don’t cloth diaper? You can wash these with your regular laundry just make sure to avoid the use of hot water (warmer than 140F/60c).
Short Answer: Line or hang dry the diaper shells and covers when possible, because we love the environment and do want to pay extra electricity bills. Longer Answer: As ecophiles, we would recommend that you line or hang dry our cloth diapers after each wash. But we have families and tight schedules and amazing dryers, too. So if you put our liners in the dryer use the tumble dry setting with medium heat. We recommend that our diapers covers or diaper shells not be put in the dryer, if possible. This is to ensure that the PUL (Polyurethane Laminate) lining which is heat bonded on the inside of the outer layer of our shell (read it again if not clear) is not eroded. The PUL is what makes our diapers waterproof and the less heat it is exposed to the longer it will stay bonded to the fabric. If you absolutely have to put the diaper shells or diaper covers in the dryer do so at a low to medium heat.
You know your Lil Helper swim diapers have been designed for a snug fit that ensures that you, your baby, and your unicorn shaped floaty are the only ones bobbing around in the pool. We often get asked about whether or not it “Holds” pee. While the diaper is stellar at keeping poop contained, while water and pee are able to pass through. This is because it is lined with mesh, to allow breathability, so that tiny tush isn’t full of water.

Get rid of the Walmart swim diapers

After having our first poop in the Walmart swim diaper, I knew we needed to find a better option; one preferably with clips so avoid poop don’t the legs again 😅 with searching came the lil helper swim diaper! I absolutely love the clips and how the diaper grows with your little one! It also doesn’t hold water so they don’t get the saggy butt when they get out of the pool. Overall love this product and can’t wait to use it for years to come!

Great for little!

We started swim lessons last month for our 7 month old. All the other babies were using disposable swim diapers. I loved these so much I ended up getting another couple pairs! These don't get bogged down with water like disposables & they keep the pool poo free. I had several people ask about them & I told all of them this brand is worth it!

Clarissa Brillembourg
Love these!

I bought One to try when my baby was born, and when I finally Got to use it I LOVED it. I love NOT buying disposable swim diapers and using these instead. I love Them so much that they gave me the confidence to buy the trial pack of reusable diapers and try those to see if they replace our everyday diaper. 100% recommend you try these!

Well made

I finaly decided to replace our old swim diapers by these and I should I've done it sooner. The fabric doesn't hold water (just like a swimsuit) so my kids are more comfortable. Poop stay in, like it should.
