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.
