    Highly Absorbent
    The bumGenius one-size cloth diaper is one-size off the shelf. In addition to the regular insert, we are including a newborn insert/booster with all version 3.0 diapers. The newborn insert is designed to reduce bulk for small babies.

    When the baby outgrows the newborn insert, it works great as an overnight booster or extra absorbancy for a heavy wetter.

    Cloth diapering has never been so easy!
    bumGenius! one-size cloth diapers offer an industry first, stretch-to-fit tabs (patent pending). Our unique tabs provide a comfortable fit and trim look. This simple design makes cloth diapering as easy as using disposables. bumGenius! one-size cloth diapers are perfect for care providers who might be resistant to cloth diapering!

    Less Clutter
    bumGenius! One-Size Cloth Diapers easily fit most babies from 7 pounds up to 35 pounds. One diaper for multiple children simplifies laundry and the diaper drawer. No more sorting by size or having to carry multiple diapers when going out. Three snap-downs on the front of the diaper (patent pending) adjust the rise as your baby grows. For newborns, fold down the insert stopper for an extra-small rise.

    Only the Best for Your Baby
    The soft, waterproof outer fabric keeps the diaper just as trim on a newborn setting as it is on a toddler. Soft, sueded inner fabric wicks moisture away from your baby's skin. Super stretchy, ultra gentle leg and back elastic with rolled out casings keep the yuk in and to help keep red marks away. Plus, our unique covered (patent pending) pocket opening keeps wetness completely off of your baby. After the diaper has been used, you can even avoid messes in your wet bag by rolling the diaper up and fastening the tabs before storage!

Frequently Asked Questions About Cloth Diapers

Do people really still use cloth diapers?
Yes! As a matter of fact, cloth diapering has become quite the vogue thing to do, especially among environmentally conscious parents. All of the new choices in cloth diapers have made it as easy to use cloth diapers as it is to use disposable diapers.
How many do I need?
A newborn can easily go through twelve cloth diapers in one day so we recommend purchasing 12-18 cloth diapers in the newborn or small sizes. An older baby doesn't need quite as many diapers, but you should still plan for 8 diaper changes and an overnight solution. Once you've picked out your diapers, don't forget to get two or three dozen cloth baby wipes, a waterproof diaper tote for your diaper bag and, if you have an older baby, aMini Shower Diaper Sprayer is a must-have.
What does everyone else buy?
There are lots of cloth diapers on the market we decided here at Natural Mom & Baby to offer the most cost effective and all around convenient diaper we know of. This is why we offer the bumGenius One-Size Cloth Diapers. They are the popular choice when convenience is essential. From birth through potty training our customers love these.

If you are cloth diapering on a tight budget, These will certainly pay for themselves quickly. Some of the other items families may consider to make cloth diapering that much easier are: 
Diaper sprayer (enableing you to easily clean your diapers in the toilet without "getting your hands dirty") 
Diaper pail (to store your diapers until wash day)
Cloth Wipes (they are easy to manage along with the diapers)
Bottom Cleaner (This smells wonderful and works very well to gently clean babies bottom)
Diaper Oder Neutralizer (This will keep odors down and your diaper pail and nursery smelling fresh) 

What about overnight diapering?
Our top selling overnight cloth diapers are bumGenius combined with two of our ultra-absorbent Cotton Babies microfiber terry inserts or our Hemp Babies hemp inserts. 
I just received my diapers. How do I start?
Prewash bumGenius, and other polyester diapers once before using. Microfiber inserts should also be washed once before using.

To reach their full absorbency, unbleached Chinese prefolds and hemp products should be washed 5-8 times with very hot water and approximately 2 tablespoons of detergent in each load. This removes oils and waxes from the cotton and hemp (normally removed during the bleaching process) that prevent liquids from absorbing into the diaper. White prefolds only need to be washed 3-5 times before use. To shink the products to their proper size, we recommend drying between each pre-wash.

My unbleached prefolds/hemp inserts are leaking!!
Make sure that you've prewashed them enough. Remember, they need to be washed 5-8 times in very hot water with a tiny bit of detergent in each load. If you have used your diapers before and haven't encountered this problem, I recommend putting a folded soft terrycloth washcloth inside the prefold diaper. The terrycloth will be able to catch the pee before it rolls off the diaper. The cotton is absorbent, but sometimes it doesn't quite 'grab' the liquid fast enough to keep it from rolling off and around the edge of the cotton. This method will also enable your baby to go coverless in a prefold diaper with fewer leaks.
My baby is in a daycare center. Will I be able to cloth diaper?
More and more daycare centers are open to the idea of using cloth diapers. They will require that you provide a place to store used diapers and that you take your diapers home with you each night for washing. Be aware that your daycare center may be governed by state regulations related to diapering. You may find that initial discussion with the daycare more successful if you take the time to educate yourself about laws in your state first. Home-based or private daycare providers are probably going to be more willing to cloth diaper your child. Remember that ease of use is going to be an essential bargaining chip! Because public perception of cloth diapering still revolves primarily around flat diapers, vinyl diaper covers and pins, it may help to have one diaper from the system of your choice on hand that you can use to demonstrate the ease of use.
What do I do about the poop?
Good question! I think everybody asks us this question. It is important to note that it is EASY! Modern inventions (like flushable liners and the diaper sprayer) have taken the grossness factor out of this issue.

First of all, your baby will go through different stages as they grow. Poop tends to change as your baby grows.

  1. Breastfed baby poop is water soluble. You do not need to remove breastfeed baby poop before washing.
  2. Around 4-6 months of age, many babies start solids through cereal. At this point, stools transition to a thicker "peanut butter" consistency. For best results, this should be removed (as much as possible) from your diapers prior to washing.
  3. Formula fed and older babies typically have firmer stools. This should also be removed from your diapers prior to washing.
The solutions below are what we commonly recommend to families. We have many families who love the diaper sprayers and many others who swear by the flushable liners. We recommend that you evaluate the options and choose the one that you will actually use.
  1. Flusable diaper liners laid inside the diaper allow the poop to be easily removed from the diaper. Just peel the biodegradable liner out of the diaper and flush the mess away.
  2. Diaper sprayers are another fantastic solution. This handy little device attaches to the plumbing behind your toilet and allows you to easily spray the mess off. The small holes and concentrated spray allows the Minishower to do a better job cleaning diapers off than any other sprayer available. The Minishower does double duty during potty training as it cleans out potty chairs. The adjustable spray can also be used for feminine hygiene during the postpartum period.
  3. It is easy to shake firmer stools off of the diaper into the toilet (no spray or liner required).
  4. In a pinch, good old fashioned dunking will get the job done.
Will my house smell like a diaper pail?
You shouldn't have anymore odor that you experience with disposable diapers. Many cloth diapering parents actually claim to smell less diaper pail odor when using cloth diapers simply because their cloth diapers aren't full of perfumes (like disposables).

Smell-eze are an inexpensive way to deal with diaper pail odor. These non-toxic deodorizers are perfume free and do a great job eliminating diaper pail odor.

bumGenius Odor Remover does a fantastic job removing the odors in diapers.

The best way to combat diaper pail odor is to wash cloth diapers frequently, at least every other day.

Finally, be sure that your diaper pail has a lid on it and keep it closed.

Washing Cloth Diapers

Basic Washing Routine:
  1. Wash the entire load on cold with detergent. Washing once on cold water is important to remove leftover "yuck" from your diapers.
  2. Wash the entire load again on warm or hot - also with detergent.
  3. Do a second rinse.
  4. You can dry almost everything in the dryer.

If you’re having problems with diapers that stink after washing:

  1. Try an extra rinse. Sometimes detergent residue can cause diapers to smell.
  2. Wash once with a small squirt of liquid Dawn. Rinse well.
  3. If the previous solutions don’t work, try 1/4 cup of bleach in the warm/hot wash cycle.

What detergent should I use when washing my cloth diapers?
Choosing the right detergent for your diapers is essential!  

What detergents should I avoid?
Do not use detergents containing pure soap, enzymes, fabric whiteners, fabric brighteners, fabric softeners or anything scented.

Do I have to sanitize the washing machine after washing my cloth diapers?
Absolutely not. If the diapers are clean, the washing machine is clean.

How do I use baking soda or vinegar when washing my diapers?
Water, detergent, the sun and occasionally a small amount of something santizing like bleach is plenty to get your diapers clean and stainfree. We do not recommend the use of any other additives when washing your cloth diapers. Additives can damage the waterproofness and elasticity of your diapers. In addition, they can change the pH of your diapers resulting in skin irritations.

My diapers are stained. Now what?
The best stain remover is the sun! Wash your diapers and then lay them out wet on the lawn with the stain facing the sun. It usually only takes a few hours before the stains are gone! If some remnants of the stain still linger, rinse the load again and repeat the process.

What do you do with stinky diapers or covers?
Wash your diapers again! Most of the time, stinky diapers just aren’t clean yet. Detergent residue or build up may also cause odors to be retained. Check the rinse water to make sure that you don’t see suds. If you do, use less detergent. A warm wash with a squirt of liquid Dawn (the dish detergent), rinsed well, does a great job removing stinky residue from diapers. When all else fails, try 1/4 cup of bleach in a large hot wash load.

My diapers smell like ammonia after being worn. What should I do to fix this problem?
The chief culprit for an ammonia smell is detergent scent or detergent residue. Make sure that you are using an extra rinse when washing your diapers and that you are using a detergent that does not contain any perfumes. A warm wash with a squirt of liquid Dawn (the dish detergent), rinsed well, does a great job removing stinky residue from diapers. Using 1/4 cup of bleach may be occasionally necessary to kill odor causing bacteria in the diapers.

I live in an apartment and need to wash my cloth diapers in a laundromat. How do I do this?

When we started cloth diapering, we lived in an apartment and did not have our own washer and dryer. We were cautious about diving into cloth diapering so we started with a diaper service for three months and then decided that we were ready to venture out on our own. We’ve discovered that cloth diapering is very doable -- even when you’re washing in a laundromat!

The system that we found that worked for us was simple:

  1. Wash everything together.
  2. Wash the load one entire cycle on cold using just a little detergent.
  3. Wash the load again one entire cycle on warm or hot using 1/4 - 1/2 the regular amount of detergent.
  4. Sort the pocket diapers and the covers out of the load and dry everything else.

A few extra things to note

It was important to have enough diapers to wash once or twice a week (at the most). I also used a pail liner to avoid hauling the entire diaper pail to the laundromat. We had 48 prefolds and washed twice a week with a young, breastfed baby.


It cost us $3 a week to wash diapers once a week. I paid $1 for each wash and $1 to dry the diapers. When evaluating the cost benefit of cloth you’ll want to calculate how much extra you’ll spend washing twice a week versus just buying enough diapers to last all week. If you spend an extra $3 a week washing diapers, in four months you could have purchased another two dozen prefolds with the money you saved by washing once a week. We found that it cost less in the long run to have a seven day supply of diapers.

An important note! If you are going to buy a one week supply of diapers, we strongly suggest that you purchase 100% cotton prefolds. Prefolds are the easiest product to get clean after sitting for a week in a diaper pail.
