our Story

I have first tried using the Bum Genius One-Size all-in-one (AIO) diaper with my then 26-month-old toddler. She was 31 pounds upon first using it and as of first writing this review.

Our first official use happened around 5 am to 9 am. It is a timeframe when my daughter consumes the least milk (4-8 ounces). It survived the 4-hour standard timeframe of comfortable wetness.

My daughter was not asking me to remove it and it also didn't feel very bulky despite that it was soaked. I touched the inserts upon removing it, and although it was wet, it was the kind that was still bearable and comfortable.

There are nights when I decide to add an extra layer of Charlie Banana insert. I was expecting to change it in 2 to 3 hours, but to my surprise, although it was soaked, there was NO leak at all.

I officially trusted this diaper as an overnight diaper that can last for up to 6 hours of comfortable wetness WITHOUT leaking provided that you add an extra insert. Without an extra insert, it can only last up to 4 hours.

The fact that it dries very fast is a big plus in my book.

Adjusting the size of the cover is easy. Buttoning to get the right size is a no-brainer. Just snap together the two furthermost buttons and you get the smallest size. Leave it unbuttoned to get the largest size.

I like how stretchable the cover is. I was able to fit it with my then 31 pounds daughter in it. However, I used the furthest buttons.

unique inserts

An all-in-one diaper like this is like a typical disposable diaper, except that it is made of cloth and the inserts are sewn into the cover. Compared to other AIO diapers, the Bum Genius guys did not sew the inserts onto the cover. They did it in a way that you can add an insert in the middle for added absorbency and the sewn-in inserts will be the topmost layer to wick the moisture away from the babies' skin.

It is brilliant for them to design it that way because this kind of design allows for easier drying. Typical AIOs drying time usually takes longer because the inserts are fully attached to the cover - but not this one.

See the photo.

covers reusability

Unlike pocket diapers and all-in-two diapers, this is probably where the additional cost will come in. YOU CANNOT reuse the cover because as soon as it is wet, you have to use another one again.

While it is convenient just to throw it in the diaper pail/wet bag after it's soaked, be prepared to get more of this if you are going for the all-in-one way.

A typical of 24 pieces would be a comfortable number to acquire. It will last you for 2-3 days. A good washing schedule, if you have 24 pieces in your stash, would be every two days.

care instructions

Machine wash and tumbling it dry is fine. If you have access to direct sunlight, it is BEST to line dry them. Otherwise, spinning it and air drying does the job too.

I have started using the wet bag system and find them better than the old-fashioned way (wet pail system) I have used in the past with the Charlie Banana cloth diapers.

As for the detergent to use, it is fine NOT to buy the recommended detergent as long as you don't use fabric softeners and bleach. We would usually use our standard baby detergent Purex* for washing them. They work fine, and there's no trace of stinky smell after washing them.

best use

When using for a toddler, the Bum Genius AIO is best used during daytime. The absence of bulk will let your toddler move freely.

However, night time use will always require an additional insert. Make sure that two buttons per side are securely snapped in. Attaching just one button per side will make the thigh gap area too loose which will make it prone to leaking.

the best part


What I like most aside from how easy it is to adjust the sizes, is the soft and breathable feel of the materials used. It is also not very bulky which makes it ideal for daytime use when my daughter is running around as bulky cloth diapers tend to hinder the quality of her walking/running.

Also, I like that I can put extra inserts for added absorbency should I need to use it for overnight use.

It's not bulky although it's soaked

the tough part

It doesn't leak IF it has an added insert, like a Charlie Banana insert, and it always needs an extra insert as an absorbency "booster."

will i buy it again?

I’d buy it for a newborn or a younger baby less than 1 year old. I’d even get it for their overnight use without worrying about getting additional inserts.

However, if I only have Bum Genius AIOs in my stash, I’d surely rush toilet training my kiddo - before they become a heavy milk drinker or a chubby toddler, which mostly happens a little way past 1 year old.


I like the fact that it is not bulky, but less bulky means I need to change it after one pee. The best use of this all-in-one diaper is to stuff an added insert so that you can use it longer, maybe 2-3 pees more before changing it.

It can even be an overnight diaper and a diaper for going out, only when you boost the absorbency with inserts such as the ones I tried, Charlie Banana insert and Naturally Natures Bamboo Insert.*

When it comes to cloth diapering, all-in-one is the fastest way to put your baby in diapers. You don't have to button the inserts in the cover like how you usually do in all-in-twos. You also don't have to stuff inserts in the pockets like how you do it with the pocket diaper system. You just have to grab the all-in-one diapers and put it on to your little one. Convenience is the major selling point of this AIO system. 

However, be prepared to get more pieces. That is because, once it's wet, you will have to replace it with a new one like how you do it with disposables. But don't worry because you are not throwing it away! You are just simply collecting them for washing 2 or 3 days after.

The best thing is, it dries easily compared to other AIOs since the inserts are not fully sewn into the cover. If AIO diapers are the way you decide to go with cloth diapering, BumGenius AIO one size diapers are definitely worth checking out!

They are not bulky, are lightweight, and easier to dry because the inserts are not fully sewn into the cover. There is also a nice feel of soft materials used.

On the contrary, covers can be made larger for chunkier toddlers and inserts can be made thicker for overnight use.

Nevertheless, it is a breathable cloth diaper that can be customized for added absorbency needs.

Sadly, we have to stop using it as it cannot fit my 37.4 pounds toddler anymore - way over the Bum Genius all-in-one’s recommended fit (up to 35 pounds). 

Few days away from my daughter's 4th birthday - my last update for the Bum Genius AIO cloth diaper. While it is still tempting to continue testing the cloth diapers in our stash, it would be selfish of me to not start toilet training her just for the purpose of still wanting to know how these diapers will stand the test of time.

If we ever get pregnant again, I am sure this diaper will still be usable and still perform decently. 

Is This The Answer To What Is The Best All In One Cloth Diaper?

Don't' forget to leave any question below if you have any. 🙂



I'd love to know your thoughts in the comments section below!

Your email address will not be published. Required fields are marked

  1. Comparing AiO to Pocket diapers, is there a difference in their life span? Or are they good for just about the same length of time? We are wondering if the pocket with removable inserts would make the diaper as a whole last longer because if needed, you could just replace the inserts.

    1. Hi Martina,

      Thanks for your question. It depends on the brand. My daughter has been out of cloth diapers since May 2018. Most of her 4-years used pocket diapers can still be usable by another child.

      For example, my Charlie Banana pocket diapers stash still looks good. However, I wouldn’t expect the same performance when compared to new ones.

      You are correct to say that you can replace the inserts but you have to make sure that the covers are still “thick” and waterproof (there’s a waterproofing material inside the Charlie Banana’s pockets).

      As for the All-In-Ones, my Bum Genius AIO also still looks good. But the customization is a little limited since the insert is already attached. Unless you’ll unsew the inserts one by one and do personalized customization, which I think is quite a work.

      I hope this helps.



  2. I loved the fact that it is not bulky although it is soaked which is something very difficult to find these days. I was looking for one such product which would be easy to use and even not irritate the skin. I think this product is worth a try, thanks for the sharing with us 🙂

    1. Hi Shrey,

      You’re welcome. 🙂 Let me know what you think once you have tried them. 🙂 By the way, thanks for dropping by my site.



  3. Pitin, I’m glad to hear that the Bumgenius AIO has worked great for you. I’m going to head over and check the rest of the reviews out on Amazon. I think it’s safe to say that I’ve found a quality cloth diaper. 🙂 It’s too bad their cover couldn’t be crafted like the Thirsties Duo. It would be great to have a cover that I didn’t have to toss in the wet bag after one use.


    1. Hi Jonathan,

      The Bum Genius AIO is designed to be tossed away for washing after one use, just like disposables. But at least, they are reusable after washing. I think an All-In-One diaper is not the type that you are looking for if you don’t like the idea of tossing it away to the wet bag instantly. I think you can check out some of the pocket diapers as well as you can convert them to an All-In-Two system. But I highly suggest that if you are looking for covers’ reusability, you should check out the rest of the All-In-Two diapers.


  4. I haven’t tried BumGenius, but I do have some FuzziBunz* one-size cloth diapers. They have the inserts and adjustable straps too. But my question is how do you keep them from just gradually getting discolored on the inside? I guess washing them immediately after being soiled would help, but I’m not cloth diapering 24/7, only like 1/4 the time, really. So they sit in their wet bag for a bit before being washed. I just don’t use bleach and harmful cleaners because it gets stuck in the cloth. What would you suggest?

    1. When you say “discolored on the inside,” do you mean the inside of the covers turn yellowish instead of staying as white as before? I thinking sitting too long in a wet bag and having it unwashed for more than 3 days is one of the factors. Rinsing the pee with a bidet and removing any residue would help too – make sure you always do it before throwing them in the wet bag. Since you are not using any bleach and other additives, the only “natural” way aside from the above mentioned routine is to line dry them under the sun. 🙂

      I hope this helps.



  5. Hi Pitin,

    I’m a little lost here – could you please explain the difference between AIO, AIT and pocket diapers?

    I also don’t quite understand the part about inserts – and pieces. Are they one thing or are they different parts of a diaper? By getting more pieces, do you mean getting more inserts? Did I get it right that inserts are re-usable, but you need to wash them and give them some time to dry?

    Sorry if this sounds a little dumb – I am a father of three and I only used a cloth diaper a few times and it wasn’t great. I didn’t think about it ever since, but your post somewhat re-kindled my interest in them 🙂

    Thank you in advance!

    1. Hi there,

      All-In-One diapers consist of only 1 piece. The inserts (the material that is responsible for absorbing fluids), is usually sewn into the cover making it easy to deal with as you only have to put them on to your child like how you would do it with disposable diapers. Sometimes, it is good to add an extra insert (pad) to get the absorbency you need especially at night and for heavy-wetters.

      All-In-Two diapers consist of two pieces. The first one is the cover which does the job of containing any wetness. The second piece is called the insert (or soakers) which is like a pad and is responsible for absorbing liquid. You can mix and match covers and inserts from any brand as long as the size permits. The covers usually have buttons in them for you to button the inserts to keep them in place. Some don’t have buttons and you just lay the inserts on top of the covers in that case.

      Pocket diapers are like All-In-Two in a way, except that the covers has pockets. And you slot the inserts inside the pockets. Pocket diapers usually come together (cover and insert) when sold. Although you can also use a different brand of insert to a different brand of pocket cover, as long as the size is compatible.

      If you are going for the All-In-One way, getting more pieces means buying more pieces of the cloth diaper since it works as a disposable – use it once and throw it (for washing in this case). All cloth diapers are reusable – be it all-in-one, all-in-two, pockets, and the inserts/soakers are washable too! You only throw them for washing. You throw disposable diapers forever – that’s the difference. 🙂

      I hope I manage to clarify some of your confusion. 🙂



  6. Hi Pitin!
    I was thinking to buy colth diapers for my twins who are 15 months old and have under 20 pounds. But I have some doubts about the size of the diapers, as my girls are quite small… How old and heavy was your baby when you first started using it?

    Is it any difference using these diapers in summer and wintertime?

    Thanks for the answer in advance!

    1. Hi Spela,

      The size is adjustable for babies from 7pounds to 35. We first used it when my baby was already 31 pounds. And I highly recommend this for overnight diaper and for going out. Make sure to add one more insert for maximum absorbency.

      I was a little sad when I discovered this diaper late. But nevertheless, I am still happy I have found it just nice before my daughter is already potty-trained (although she is nowhere near potty-trained).

      Your 20-pounds twins’ little bums will surely appreciate this diaper. The fabric is soft and wicks the moisture away from the skin. I haven’t used them for winter-time since there is no winter in my location. But I can imagine the only issue you would have is the drying time. If you spin them dry, I am sure they will be ready for use in 24 hours.

      I hope this helps.



  7. Hello,

    I just thought that I found this “high-tech” diaper quite amazing. I would sincerely consider getting one of these. I like how you stated that it doesn’t leak as compared to the traditional diapers that’s being bought at convenience stores. I just got a question, since you showed pictures of pink diapers for girls. I was wondering if there are blue diapers for boys.


    1. Hi Armand,

      I noticed that colors, patterns, and designs are always updated. It is made to cater both sexes so having it for a baby boy would not be a problem at all. 🙂


  8. Hi Pitin.

    I really like your post. As a parent of three, I can definitely relate to “diaper issues”. We use disposables with our three children, mostly because it is so convenient. However, I’m not too fond of the whole use-then-throw-away attitude, so I just might convince my wife to try this instead and this article will definitely help.

    Great post.


    1. Hi Ossur,

      I am also not a fan of throwing away something every three to four hours. In your case, make that times three. If convenience is your main goal, why not try to do it slowly. Start with cloth whenever you are all at home and still use disposables at night and when going out. When you have slowly adjusted to cloth, you can slowly start using them at night too. I realise there are so much more better cloth diapers options and combinations of inserts and covers to use at night. And they are way better than disposables! I will definitely be sharing my experience with four more cloth diaper brands we have been testing at night for a month now. I’ll keep you posted.:)



  9. I notice that cloth diapers are becoming more and more popular, and a good thing too, as it does save our natural resources. I am sure it also works out a whole lot cheaper to use these for your baby instead of disposables. The only thing that puts me off is all the washing.

    1. Hi Michel,

      I used to do the “wet pail” system. However, it is now more convenient to wash cloth diapers compared to before. Upon removing the soiled diaper from your little one, you can clip it to a Spray Pal* that you can clip the diapers into so that you don’t have to hold it. You can after use a bidet or Toilet Sprayer* to rinse off residues or rinse the pee away. The spray pal will also serve as a SPLATTER SHIELD so that you don’t get yourself or the surrounding areas wet. I personally use a wet bag* nowadays to store my soiled cloth diapers. The surroundings don’t stink with a wet bag in hand. A diaper pail* also does the same job for keeping the smell hidden until it is time for washing.
