Best Bottom Diaper Features

After years of experience, Nicki, the owner of Nicki's Diapers created a new diaper taking the pros of all the different diapering systems and eliminated the cons. This resulted in the Best cloth diaper system available - trimmest fitting and highly absorbent! To help reduce early confusion and that overwhelmed feeling when researching cloth diapers, the Best Bottom Diaper has simplified cloth diapering while making one of the most economical systems. The Best Bottom Diapers one size system is not a pocket diaper, not an all in one, not a fitted diaper, and not a prefold system... it is the best of all types!

Best Bottom Diapers - Pros and Cons

How Does The Best Bottom Diaper System Work?

Simplify, simplify, simplify! Many may start researching cloth diapers, get overwhelmed and quit. Best Bottoms Diapers are YOUR solution! So easy to use yet comes with lots of options so you can get a customized system for your baby.

1. Adjust front snaps to achieve the size needed.

2. Snap insert into diaper.

3. Put diaper on baby and go!

4. When baby needs a diaper change snap out soiled insert and snap clean one in.

5. Put diaper on baby and go AGAIN. The Best Bottom Diaper shell is wipe-able and can be used multiple times before washing but you may want to air dry between uses but it is not necessary.

Best Bottom Diapers - Easy to Use!
Best Bottom Diapers - An Inside Look

We recommend getting as many shells as your baby poos in a 2-3 day time period (for newborns count how many explosions they have!!). We have found that poo does stay on the insert most of the time but in some cases it may not (but it will stay in the diaper cover avoiding an embarrassing mess!) Three different size inserts are available in several different materials. We don't believe in a one size insert. Newborns and toddlers are not the same size so in order for a one size insert to absorb enough for a toddler it will be HUGE on a newborn. You may not need all three sizes of inserts and can skip the middle size - it is all up to you! We recommend approximately 24 inserts per size.

So to make it SIMPLE you will need approx 8-10 shells and 18-24 inserts per size. How easy is that?!


Fits from birth to 35+ lbs. We added special leg gussets to help keep everything in, adjustable rise with four settings, and overlapping closure in both snap and hook & loop. This is a very trim fitting diaper so please be extra careful that none of the insert is sticking out of the shell. Also, after the diaper is on, pull the leg gussets out around baby's legs. This will guard against leaks and help avoid any red marks.

Best Bottom Better Fit Instructions


Available in both snap and hook & loop as well as bright colors and cute prints! We have taken great care to use color coordinating snaps for a great looking diaper.


Save tons of money yet still get the convenience!


The highest quality of materials available have been selected with as much of the raw materials made in the USA as we could find. The entire Shell is made with USA-made materials! ALL of our products are proudly handcrafted in the USA at local factories helping to support the local economy and reduce our environmental impact. We use durable snaps and hook & loop, double layer of waterproof PUL creating a perfect no-leak sturdy shell with a wipe-able inside lasting for many washes.


We wanted to keep it simple but know that our customers want choices! We have created four different types of Regular inserts to snap into the shell for everyday use. You can mix and match meeting all preferences and needs. All insert types are super trim making the Best Bottom one size diapering system one of the trimmest cloth diapers around. We offer each of our Stay Dry, Hemp/Organic Cotton, Bamboo and Stay Dry Bamboo inserts in three different sizes. Sizing is approximate and will depend on size and shape of baby as well as how heavy of a wetter.

Small: birth-14lbs, Medium: 11-22lbs, Large: 16-35lbs.

1. Our Stay Dry Insert consists of 4 layers of super thirsty microfiber topped with a super soft no-pill fleece pulling wetness away from baby's bottom keeping them feeling dry.

2. Our Hemp/Organic Cotton Insert consists of 5 layers of hemp/Certified Organic cotton topped with a soft layer of hemp/Certified Organic cotton fleece. This insert is so trim you will be able to have your baby wear jeans again! Please note that hemp inserts will shrink slightly during first washings making them consistent with the other insert sizing.

3. Our Bamboo Insert consists of 6 layers of silky soft bamboo viscose. This is our trimmest insert yet, but no less absorbent! Natural fibers need to be prepped to become absorbent. Please wash and dry 4-5 times before use.

4. Our Stay Dry Bamboo Insert consists of 6 layers of silky soft bamboo viscose plus one layer of no-pil fleece. The fleece pulls wetness away from baby's bottom - keeping baby feeling dry!


We are also adding other optional inserts to accommodate for all situations. Our Overnight option makes cloth diapering at night with no leaks a breeze! Each Stay Dry Overnight insert consists of 6 layers of super thirsty microfiber made to fit with any Regular insert option of the same size. Hemp/Organic Cotton Overnight inserts are also available! Snap in the Overnight option and snap a Regular insert on top - you choose if you want to use the Stay Dry option or Hemp/Organic Cotton option touching your baby!

A Micro Doubler is also available. This option is perfect for heavy wetters, long car rides, or long naps! Each Micro Doubler has 2 layers of thirsty microfiber and is made to fit with any regular insert of the same size. To use, snap in the Micro Doubler and then snap a regular insert of your choice on top.

Washing Instructions

Oh so easy!!

Before first use the shells, stay dry inserts, and overnight inserts only need to be washed one time. Hemp/Organic Cotton inserts need to be washed 4-6 times to reach full absorbency. Please note that hemp inserts will shrink slightly during first washings making them consistent with the other insert sizing.

1. Remove solids

2. Either reuse the shell until soiled or wash day. Separate shell from insert before washing. Fasten laundry tabs (if applicable).

3. Rinse cold, wash warm/hot with 1/4-1/2 additive-free detergent, rinse (warm or cold).

4. Tumble dry or line dry inserts, line dry shells. No fabric softeners or rash creams (if you need to use rash creams put a barrier between baby and diaper for example a flushable liner or reusable wipe work great).

We recommend washing every 2-3 days. We have found that the Best Bottom Diaper system washes beautifully as it takes up less space in your washing machine allowing more room for agitation getting your diapers super clean.

I dont know why I even have pocket diapers...I LOVE Best Bottom Diapers..I like that I can re-use the cover 3 or more times and just change out the insert..less wear and tear on my covers! I love that there is less bulk in my wetbag and my washer, and that the microfiber stay dry inserts are SO absorbent! The covers do run a little on the small side and I wish they were just a little bigger..other than that this system is my favorite and its way cheaper than a pocket diaper!

Love these diapers. I am brand new to cloth diapering and these were so easy. A friend had given me a few pocket diaper and they were so annoying I almost gave up before I started. Then I saw these and I'm hooked. They are amazing!

Good Fit!
Our two month old is a tiny little thing and didn't fit into any of the one size diapers we had for her. We heard best bottoms work well even on newborns. We decided to try them and love them! Nice and trim and easy to use even for grandparents and daddy who aren't cloth-savvy.

Best Bottoms fit
I have 5 Best Bottoms covers and many inserts, they are my go-to diaper. I originally had purchased mostly all-in-ones but found them too bulky to fit my son's skinny legs. Best bottoms fit well, even now that he has filled out considerably. And they are just as easy as A-I-Os, only requiring one more step to snap in an insert (and so much less expensive!) I had one minor defect on one of my covers in that one snap (one that changes the rise) is bad & comes unsnapped EVERY time I go to put it on him. Otherwise great quality & feel solid-like they will last forever. Highly highly highly recommend.

Best Bottoms System
As a first time mom, I researched the various cloth nappy systems out there and decided an AI2 systems was the way I wanted to go. Best Bottoms was recommended to me and I loved the concept of the insert snaps that keep them in place. After using BB for the past month, with plenty of trial and error with adjusting the snaps to fit my 2 month old bub, I am very satisfied with the system. It does take more time to change the bub's nappy and a lot more cleanup/washing effort, but I am happy that I no longer have to buy disposables nor is our rubbish bin filled with nappies. My bub is a bit on the big size for his age and by the time I got the BB system, the small inserts no longer fit, as he was already on a larger riser on the shell. I would probably get more of the M and L inserts and drop the S as they only use the small for a short amount of time. I love all the different shell designs and how many of them are unisex. Overall I am very happy with BB and would recommend it!
