Waterproof big kid diapers


I can remember so many mornings where my son would wake up in a sad, soggy puddle. Not anymore, baby! Waterproof gussets lock wetness in!

Save SOOOO Much Money - Who Knows How Long Bedwetting Will Last!?!?

Most families spend well over $600 on disposable bedwetting products per year. That's the price of a weekend vacation! Super Undies can last 3 or more years, saving you money, and saving the planet :)

Big Kid Diapers

Strong Waterproofing

Super Undies are made with PUL, which is a thinly laminated non-wicking fabric. PUL has a soft drapey feel to it, is waterproof in nature, but allows more breathability than disposable diapers. Waterproof gussets line the legs of these Undies, locking in the wetness.

Adjustable Absorbency

Underwear for night time potty training and bedwetting should be very absorbent and accommodate whatever your child can put out without leaking, but still allow the child to feel wet. This helps create the brain/body connection necessary to work through nighttime potty training, and that's exactly what our Chameleon Undies do!

Chameleon Undies 3-Pack


Chameleon Undies are a direct replacement for UnderJams or GoodNites. They are very waterproof, and have absorbency that allows you to adjust to your child's needs. Whether your bedwetter is a leaky faucet or a fire hose, the Chameleon can adapt for a good night's rest!

This set gives you three mixed-colored pairs of eco-friendly reusable bedwetting underwear, and a laundry garment bag to wash your undies in. That's enough Undies for 3 nights.  Our Undies can typically last a child through 2-3 years of growth, and can last up to 6 years of wear and tear. This means you can use them through multiple kids, or sell/donate them when your done :)

You may still be wondering if these will work for you, and we want to be very transparent about that. Chameleon Undies work for boys and girls. Our unique insert system is the bomb. It's our secret sauce to success! Use 1 for a trim fit and a light wetter. Use 2 inserts to hold back the hoover dam!

Chameleon Undies also have a build in size adjustment in the waistband to help you get a good fit and let these undies last longer. Just fold down the waistband to cinch up the rise!

While the initial cost of cloth may seem pricey at first, when you truly compare the cost you’ll find in the long run Super Undies can save you a lot of money! You can get them cheaper by purchasing them as a package deal. 

Studies show that as your child gets older it is important to embrace this area with workable and practical solutions. Kids need to know that they are being seen, heard and cared for. Ignoring bedwetting all together and quietly providing a disposable larger baby diaper can have lasting effects on a child’s self esteem. The truth is one in every four kids in a first grade classroom are still wetting the bed! By the time boys are 7, one in ten are still wetting the bed. This problem is bigger than you thought. Your kid is completely normal!

Here’s the kicker - It’s not even a problem. Trying everything under the sun to eliminate bedwetting shows kids that this IS a problem to fix, and causes them to feel powerless and broken.

A kids starts to think... what’s wrong with them? Why do they do this? The best way you can help your kiddo is to normalize it. Remove the baby diaper stigma by taking away the disposables. Give these kiddos their dignity back by providing them with a reusable cloth padded underwear that contains the wetness and just gets tossed in the laundry. A pair of super undies can last up to 3 years in size, but 6 years of regular use!  That means that by supplying your kiddo with 6 pairs of undies they will have a healthy rotation, colorful fun options to choose from every night, and no pressure to NOT wet anymore. Once you have Super Undies, no more money needs to be spent and no extra laundry is generated. Just throw your undies in with the load of towels you are already washing.

And here’s the best part - 15% of kids that switch from disposables to cloth show reduced bed wetting within the first 2 weeks of use, and THAT makes your kiddo feel MUCH better!

How To Potty Train At Night

Step 1 - Switch To Cloth

Start by using cloth, rather than disposables. You cannot effectively potty train at night if you mask the wet feeling. Your brain only has one chance per night to make the connection between the feeling of a full bladder and the wetness that follows, so make sure you do not deny it that opportunity.

Step 2 - Make Sure Your Child Gets Extra Sleep

There is a place in the brain that stays awake while you sleep called the Thalamus. It is in charge of releasing ADH (Anti-diuretic hormone) which ensures you don’t eliminate in your sleep. When your body isn’t rested well enough, the Thalamaus doesn't have the needed energy to stay awake, so you don't get that crucial ADH necessary to stop the production of urine while you sleep. When you bladder fills, it has to release. Getting thirty more minutes of sleep per night for a few weeks can be enough to restore your sleep tank and stop bedwetting. It is also a great indicator for if your kiddo is going to wet the bed tonight. Busy exhausted day? Yup, it's happening. There are a ton of other reasons why sleep is important, so you might as well give it a shot!

Step 3 - Light Up The Bathroom

You might be shocked to find out that one major cause of nighttime bedwetting is simply a fear of the dark. Making your child feel safe to go to the bathroom when no one is around can be very impactful in your nighttime potty training efforts. Install night lights low in their room to light their foot path. Keep a nightlight plugged in in the bathroom and if possible, install a toilet light to light the bowl and give your child an easy way of aiming.

Step 4 - Occasionally Have Your Child Sleep Bare-butted

When a child pees at night and the wetness is caught in the diaper, whether cloth or disposable, it is held close to the body. That limits the cause and effect feeling. If you want a real “wake up” effect, having nothing will give that to you! Sure, you have to diaper the bed instead. Sure, you have to wash a blanket in the morning. Sure, you need to budget time for a bath or shower the next day, but this is all temporary. Have your child sleep bottomless for two to three days straight to kick in that waking-brain sensation. Remember, you only have one opportunity each night (usually) for the learning moment to happen, so these methods are not a one-night solution. You will need repetition for the solution to take hold. After a few days, if you don’t see any improvement, just go back to cloth overnight underwear and give this a shot in another month or so.
