  1. Before washing, make sure any solid matter is removed from your product. For items with heavy soiling that may stain or develop odors, rinse under cold running water until the water runs clear before storing for wash day.
  2. For a deep clean, start with a pre-wash on a short cycle using warm water (up to 140°F / 60°C) and the recommended amount of detergent, such as Tide Original to Line 1. Follow with a heavy-duty, longest-cycle wash in warm or cold water, again using the appropriate detergent amount. To ensure proper agitation, add other items to create a full load.
  3. For everyday or lighter messes or items already pre-rinsed, a regular cycle in cold or warm water (up to 140°F / 60°C) with the normal amount of detergent is sufficient.
  4. Whenever possible, hang to dry. If you’re in a rush, you can tumble dry on low.

Tank Cloth Diaper that actually works

The Cloth Diaper That Actually Works

No leaks. No rash. No kidding. Our Tank Cloth Diaper is award-winning for a reason—it combines waterproof protection, ultra-absorbent layers, and the genius of our two-piece Tank Insert Set. Designed by actual rocket scientists (yes, really), it keeps moisture in check for 12+ hours, even for heavy wetters. From nap time to night time, it’s all comfort, zero leaks.

Foolproof Fit, Fuss-Free Care

If you can snap a onesie, you can use a Lil Helper. The Tank’s one-size design fits from newborn to toddler with guide snaps to make perfect fit a no-brainer. There’s no stuffing or prepping—just snap the inserts in, put it on, and go. When it’s time to wash, rinse solids, toss it in the machine, and either hang or tumble dry. Easy on you, gentle on your kiddo, kind to the planet.

Built to Last (and Last... and Last)

One diaper, countless diaper changes. Our Tank Cloth Diaper is made to grow with your child—from 7 to 35 lbs—and even last through multiple kiddos. Premium elastics, durable snaps, and PUL waterproof fabric mean it’ll handle years of wear and washing without losing its shape or strength. It’s not just a diaper—it’s an investment in comfort, savings, and sustainability.

How Many Do You Really Need?

Just the right number for your routine. If you’re full-time cloth diapering, you’ll want around 18–24 diapers so you can wash every 2–3 days. For part-time or daytime use, 6–12 diapers usually do the trick. Since each diaper comes with a Tank Insert Set, you’ll always have backup absorbency ready to go. Start small and build your stash—your wallet and the planet will thank you.

How to Wash Your Lil Helper Diapers

Simple steps. Stellar results. Make sure any solid “stuff” is already out of the diapers, inserts, and liners before you throw them in the washer. Unsnap the inserts and the diaper. Pre-wash (short cycle) in warm water using the recommended brand and amount of detergent—Tide Original to Line 1. Then run a Heavy Duty (longest cycle, max 140°F/60°C) warm/cold wash with the proper detergent amount and bulking. We recommend Tide Original, adjusted based on load size.

Hear ye, hear ye!! Lil Helper diapers DO NOT NEED TO BE PREPPED!

Yes, you heard right, waterproof diapers do NOT need to be prepped! Every diaper and insert comes to you ready to be used with all the absorption you will ever need, just waiting to wick away your baby’s wetness! (Cue happy diaper dance…) We do recommend giving the new diapers a quick wash in the laundry at least once in warm or cold water to get rid of any dust that may have accumulated from the warehouse or shipping. You will only need to use ½ the recommended amount of detergent for this short cycle as the diapers are already clean. You are just freeing them of dust.

You know when you buy your child that super sought-after toy and then get it home, only to see the fine print that all the amazing accessories on the box aren’t actually included…. Meaning more money and lots of tears (from the kids and maybe even you!).

We want to make your life as easy as possible, which is why all our reusable diapers come with a cover AND inserts. So, when you purchase a Lil Helper cloth diaper you get a diaper cover and a tank insert set. Meaning, you get the whole baby diaper so it’s ready to use without any extra purchases. How's that for easy and convenient?

Like peanut butter and jam, bacon and eggs, or moms and coffee, some of the best things come in twos. We designed our cloth diaper with two inserts to give you more flexibility in customizing absorption. You would use the small liner by itself when the baby is under 3-4 months. When the baby grows older, then you can use the large liner in tandem with the small one. This gives you customizable absorbency as your baby grows.

Unsnapping your diapers and inserts properly will extend their lifespan (and save money for you) and keep the snaps in good shape. Learn all about how a one-size diaper fits on our blog.

I can almost categorically tell you that your child will not need any diaper creams whatsoever when using our diapers. But even if you were to use baby diaper creams, here is a good reason why you shouldn't be using any creams. The same impermeable layer of waterproof protection that the diaper rash cream forms on your child's bum is also transferred on the diaper making it water-resistant.

Moisture won't be absorbed readily if you use rash creams on any reusable diaper, not only Lil Helper cloth diapers. If the diaper cannot absorb pee or poo, it will leak. We suggest avoiding all creams… yes, even coconut oil. The icing on the cake is that ultimately with cloth there is less need for the creams anyway. We change more often, reducing wetness—and you avoid any of the harmful chemicals in disposables that may also cause irritation on a newborn’s tushie.

Blown away by no blowouts!

We started using these with my daughter when she was still in standard newborn size diapers. We are now several months in and we LOVE these diapers. Cleaning them is easy, I love the colorful prints, and the tank inserts are quite simply TANKS. We’ve had maybe one leak and that let us know it was time to size up the rise - and no problems since. My friends’ babies are constantly having blowouts but we have entirely escaped that so far. My daughter will sometimes hold poop for several days but the elastic at the waist and legs still manages to hold it in when the “poopocalypse” hits. Although we were gifted many disposable diapers at our shower, we’ve only used a handful of each size because we lil helpers so much. A dry bag for dirty diapers makes it easy to use these when out of the house, and a little sprayer on our toilet makes poop removal a breeze. These were an investment but I am so glad we took the plunge.

Hey Rachael! My goodness, we are blown away by the kindness and thoroughness of your review of your Tank Cloth Diaper!! It is the very best news to read that you find them to be easy for your daughter to wear, easy for you to clean, and able to hold all of the pee and poo! It's so true: Poopocalypses, Poopnamis, Poopnados don't stand a chance in our Tank Cloth Diapers! (And now I'm on a kick to find more natural disaster poop puns :) ) We hope that they continue to serve you well and that you and your daughter have a fantastic week! Thank you for choosing Lil Helper! - Amanda @ Lil Helper

Love these diapers!

We love lil helper! These diapers have been great for my daughter, as she has sensitive skin and the minute a disposable diaper touches her she gets a rash. These diapers have held up great to many washes, and ultimately they’ll be way more cost effective than disposables.

My only complaint is that my daughter tended to leak through these when we were just using the small inserts (up until she was 12lbs, which I think is the recommended size for starting to use the large ones). She is a very well hydrated baby so I think they just couldn’t handle the volume of liquid, as nothing was wrong with the diaper absorbance. Customer support was super helpful though and provided some suggestions like adding in cloth wipes under the insert for additional absorbance. This helped about 75% of the time but we still did get SOME leaks. But now that we’re using both inserts, we have had NO issues and it’s been great. Even with the leaking I’d recommend these (just maybe not for an under 8 week old who is very hydrated!).

My ask for lil helper is maybe to offer an option to purchase a SMALL bamboo liner addition with the PUL backing for newborn sizing. I think we could have made the bulk work but the length of the large insert was just too much to fit before she was about 12 lbs. just something to think about!

Hi Hannah!! Thank you so very much for taking the time to leave a 5 star review of your Tank Cloth Diaper. Our Delight Team loved chatting with you to provide those suggestions to help bulk up for absorbency. We are always here along the way to troubleshoot fit and leaks and can be reached at delight@lilhelper.ca (just in case any other questions pop up!) :) Also- did you know that we have a parenting group on FB called 'Lil Helper Unsnapped: Parenting Tips & Advice'? We would love to have you join if you haven't already!! Thank you also for your feedback of having an option to purchase a small bamboo liner. We will pass this along to our production team!

Try just one first, don't go all-in

We really regret going all-in and getting 3 days worth of these diapers and inserts. Our baby is 5 weeks old. According to the instructions, we are using just the small insert, and her output has been saturating the insert in under 2.5 hours, leaking into the PUL and soaking her back and/or leg at least once a day since she was about 3.5 weeks old. The diaper is well-fitted and the inserts pass the absorbency test, but one insert is obviously not enough and we cannot fit both inserts yet. We've already stopped using these at nighttime.

Hopefully these diapers will work better with two inserts, which hopefully we'll be able to fit once our baby is 3 months old. Otherwise, what a waste of hundreds of dollars... Lesson learned!

Edit: increased from 2 to 4 stars -- customer service reached out to me shortly after I had posted my original 2-star review to help troubleshoot. Our baby has now been using the diapers with the full Tank insert (both small and large ones) for the past 2 weeks (since 6 weeks old) with great success! The customer service representative was very helpful in checking the fit for us, and our baby is bigger now so it's easier to fit both inserts. We've had no more leaks! Fingers crossed that we'll stay leak-free!

Hey Jaye! Thank you for taking the time to give us your feedback on our Tank Cloth Diaper and for letting us troubleshoot your fit and leaks with you. We are delighted after emailing with you that you are now leak free - don't hesitate to reach out again if you need any more help! Have a wonderful day!! - Amanda @ Lil Helper

Fantastic but small for toddlers

Highly recommended for babies and smaller toddlers. Definitely on the short side for average height or tall toddlers.

Our twin 18 month olds have had pretty constant diaper rash and yeast, so we wanted to try a switch from disposable to cloth. So far it's helped quite a bit. These diapers held a lot, with only a minor leak overnight due to fit, and wash very well. They are comfortable on the baby, and no more rash!

With my older kids we had tried some all-in-two cloth diapers and always had to wash the covers every time, the inserts on these hold enough we can go a change or two without needing to also wash the covers.

Unfortunately, we aren't going to get to use them long. My girls are nearly 18 months old, about 26 lbs, wearing 18 months-2T clothing, and between size 4 and 5 in disposable diapers. They have quite a bit of width left to go in these diapers but the rise is so low it's nearly too short already. When they get taller there's no way they will continue to fit. We've tried removing the smaller insert, but didn't gain any real improvement in rise and the decrease in absorption wasn't worth it.

I'm considering trying a pair of the training pants with the tank inserts to see if that would work.

Hi MaryAnne! We appreciate your time and your review of our Tank Cloth Diapers. It is wonderful to read that your twins' constant diaper rash was alleviated when using our Tank Cloth Diapers and that your kiddos find them to be comfortable. One quick tip on the fit for some kiddos: you can unsnap the inserts after your child is in the diaper to create more wiggle room. Our Delight team is also always here to help with fit and absorbency questions, we would love to help your girls to get a better fit so they can use these right up to potty training time! We can be reached at delight@lilhelper.ca. Warmly, Amanda @ Lil Helper
