Swim Diaper (New & Improved)

? Click at your own risk ?

There were a lot of things I expected to happen when I became a parent.

I expected a lot of sleepless nights and to be tired A LOT.

I expected to deal with tears and tantrums.

I expected to spend a lot more of my time than I would like, dealing with someone else’s bodily functions.

But one thing I didn’t fully expect, was how much parenting would teach me.

I’ve learned about a nurturing side I didn’t realize I had.

It has taught me I can be a real bada$$ when something threatens the health or happiness of the little creature I created.

It’s taught me to be a little more playful.

But I think the most profound lesson that becoming a parent has taught me, is that “poop happens.”

Now, while this may seem like a simple statement, there are actually layers to this lesson.

First, there is the more metaphorical meaning. As in, things happen that you can’t control. So roll with the punches as best you can when your child decides to hide your keys or paint your dining room walls with their dinner.

But there is also a more concrete meaning to this lesson that parents, especially, are all too aware of. As in, poop literally does happen.

And it usually happens at the worst possible time.

It could be right after you just changed your baby’s diaper.

Or it could be right after you have finally wrestled them into their carseat and gotten them buckled in.

But as frustrating as all your other “poop happens” moments may seem, there is actually one that is worse.

Let me paint you a word picture.

It is about 1,000,000 degrees outside. You are sweating, your baby is sweating, the dog is sweating.

In a stroke of brilliance, you decide to pack up the car and hit the local pool so that everyone can get a little relief.

You get you and baby changed and into the water. It is wonderful. Your babe is splashing happily away and you are both enjoying the relief of the cool water.

But then you see it. The tell-tale face.

And you know that all of your fun is about to come to a screeching halt.

Suddenly, you have visions of children running in panic and the pool being closed down for days.

This, my friends, is the mother of all “poop happens” moments.

Your first instinct is to dash from the pool before your “poop happens” moment becomes EVERYONE’S “poop happens” moment.

But then you remember, instead of a pack of disposable swim diapers, you decided to buy the new Lil Helper reusable swim diaper to try on your little one.

You breathe a sigh of relief, and here’s why:

Inflatable Floaties Only: 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.

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

Multiple Uses: 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.

Protection, Now and Forever: Your swim diaper has adjustable snap settings that will allow this diaper to fit your little one from tadpole to leapfrog. This means that if (when) this happens again (and again, and again), you won’t have to worry because this diaper will fit them from about 10-40lbs.

Economical and Effective: 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.

In the pool, at home, or at the beach this swim diaper is a must have under any swim suit or even on its own! Because here at Lil Helper, we know that everyone needs to learn that “poop happens” but they don’t need to learn it the hard way.

    Softer than silk!

    I was not expecting the silky smooth texture that brushed my fingertips as I reached in the envelope to pull out my order! The first thing I thought was how jealous I was that I didn’t have a swimsuit that was as luxuriously as soft as the swim diaper that would soon be on my baby’s butt! After spending the day in and out of the pool I have nothing but good things to say about this little piece of heaven! The fit was perfect, it dried quickly while my little crawled around, and said little had zero complaints about discomfort of any kind. This will be our go-to swim choice for the rest of the season and next one too! I’m so happy I got two!

    After doing lots of research I am glad I settled on this diaper. My toddler will let me put it on him, so that’s a win right there. When it first goes on he complains that the legs are too tight, but then will happily swim for 2 hours in it! So far so good.

    Just used the swim diaper for the first time this week and it was just perfect! Sizing was equivalent to the Cloth Diapers which was nice for my Mom Brain and my son was totally comfortable in them. We will be getting a lot of use out of this diaper.

    I got the dandylion print and it’s so cute, I don’t want to put little swim trunks over it! The diaper itself is very lightweight and soft, it feels a lot less stiff than the other brand swim diaper I own, and still has a beautiful quality cover. The inside is a gray mesh which is nice and soft. Bonus, it will also hide stains! The snaps are the same system as the Lil Helper cloth diapers, so if you’re already using those it will be easy to figure out the fit on your little one. I’ve already ordered a second one, I have a feeling we will be living in these all summer.

    I love lil helper diapers, but unfortunately the swim diaper did not hold in my little guys poop. My son is EBF and I guess his poop is a little too soft for this diaper to hold. Thankfully we tried it out in our tub first and not in the public pool

    I have nothing but wonderful things to say about this swim diaper! Perfect fit and I love that it is adjustable so that I do not have to buy one-size reusable swim diapers every season. Before this swim diaper, I bought 4 of another brand only to use them a few times each before I had to upgrade to a new size. Talk about a waste of money!

    Also, it is PURE GENIUS to design a swim diaper that can be easily un-snapped for quick removal…no more having to peel off a snug wet swim diaper (pull up style swim diapers are horrible, especially if baby/toddler has a #2 accident in them. That being said, make sure that you buy at least 2 LilHelper swim diapers).

    Seriously this is amazing! We own (or should I say owned) 5 different reusable swim diapers and this is finally one that fits the bill. It can easily fit a smaller baby, but also still comfortably fits my 30lbs toddler with plenty of room to grow. It even contains the poop and looks cute doing it.

    We love that this diaper is adjustable like the regular cloth diapers. Means we won’t have to buy a new on every summer. The fit is amazing and they keep the poop in. The darker inside prevents stains too.

    I just used our swim diaper. It works just like their other diapers except the fit needs to be pulled tighter since there are no inserts used. our baby is 5 months and was on some of the smaller settings, so maybe if your baby is on the small side it might not be snug enough yet. Otherwise its great and we bought two.

    I love that this swim diaper is adjustable…. it’s why I love the lil helper diapers- one size fits all!!
    Again, super cute prints. Just make sure you don’t follow your diaper settings…. you need to make this diaper tight so nothing escapes, and there aren’t any liners to fill the diaper.
    Totally recommend!

    I had initially ordered two for my son (space dinos and parrots) and then had to come back and order one more before we went on holidays. They are so easy to use, fit beautifully, and have such amazing patterns. I recommend them to everyone who wants re-useable swim diapers – and some that probably don’t!

    These swim diapers don’t just look great, but they are amazing at catching unwanted floaters in the pool :p
    Can’t wait for the summer. We will be using these every day! Bought 2 swim diapers but might have to add a couple more to our collection 😉
    These are even great for non cloth parents as they are waaay better and waaayyy cheaper than the disposable options!

    This swim diaper is great! You don’t have to be a cloth family to use this diaper. It’s easy to use, slim and fits under a suit, will fit your baby or your toddler, contains the mess, and decreases landfill. Also- the prints are adorable… What more could you want in a swim diaper?

    My fav aspect of this swim diaper is the fact that they are ONE SIZE fits all! Not having to shop for bigger sizes (sometimes within the same season!) is a great bonus. We are using the same swim diaper we had last year (plus the couple extra we’ve added to the mix) this year and loving it just the same.

    I love this swim diaper for many reasons.
    1. It grows with bub- my guy is 3 month and this will last him at least another summer
    2. It’s lightweight and not bulky like some other swim diapers
    3. The prints are so cute (we have Narwals)
    4. It doesn’t absorb a lot of water like the horrible disposable ones do
    And finally 5. Of course it’s much better for the environment:)

    With 6 months of Lil Helpers catching poop behind us it only made sense to get swim diapers from the same company for Baby’s first pool foray. The other ones were so soggy and awkward fitting in the tub it was sad.

    This swim diaper is soft and cute and most importantly does it’s job well. Other Mamas in the changing room are always asking about it while they pull soggy disposables off their kids. I put Baby’s suit on over the swim diaper (ocean blue diaper with hot pink frilly swimming bottoms…) but I’m sure we will just use the swim diaper as bottoms a bunch as well (Dandy Lions are on their way). Also, Baby is back to the smallest snap settings since there are no inserts – the nostalgia is real.

    Our swim school requires two reusable swim diapers to be worn by kids under the age of 3, or potty trained. Everyone else uses the solid colored suits from the swim school but we have the super cute succulents print!

    Reusable diapers are required in our swim school pool because they hold in poo better AND if a disposable breaks it will clog the filter so reusables are overall better for the environment AND your swimming pool!

  • Lil Helper Diapers are designed to fit your baby from the day they come home (or soon after) to the day you release your fully potty-trained child into the wild! We have tips and tricks out the ying yang to maximize your leak protection at every stage! These videos are a great start:

    Fit for under 7 pounds

    Fit for newborn

    Fit for 20 pounds

    Fit for toddler

  • Here's a video by Mohammed, Chief Doo-Doo Officer at Lil Helper explaining how to take care of the snaps. Enjoy.
