Index of Cloth Diapering Terms

I’ve been a fluff addict since I started cloth diapering my first baby five years ago. We’re on our second baby now, and I still love reading about and trying out new diapers. As part of my quest to spread the fluffy love, I’ve put together a list of some commonly used cloth diaper terms as well as a list of cloth diapering resources that I found useful back at the beginning of my cloth diapering journey and still use today. If you’re new to cloth or just wondering about this cloth diapering thing, I hope you’ll find this info helpful.

Common Cloth Diapering Terms

AIO – All in One – A style of diaper that is just what it sounds like. The waterproof outside layer and absorbent inside layer are sewn together all in one piece. This style is most similar to a disposable diaper. (Examples: bumGenius Freetime AIO Diapers, Smart Bottoms 3.1 One Size Diapers)

Smart One inside

AIO diapers come complete all in one piece.

 AI2 – All in Two – A style of diaper where the waterproof outside layer and the absorbent inside layer are separate pieces. The absorbent layer may be snapped in or simply laid in the outside shell. (Examples: gDiapers, SoftBums Echo Diapers)

Aplix – A brand of hook and loop fastening tape.

Booster – A second insert added to a diaper to boost absorbency. Also called a doubler.

Cover – A waterproof layer wrapped over a fitted, prefold, or flat diaper, and usually fastened with snaps or hook and loop tape. (Examples: Flip Diaper Covers, Bummis Super Brite Wraps)

Doubler – A second insert added to a diaper to boost absorbency. Also called a booster.

DSQ – Diaper Service Quality – Term used for prefold diapers to denote high-quality, long-wearing prefolds, suitable to withstand the wear and tear of frequent use and washing as would be found in a diaper service company.

Flat Diaper – Large square of one layer of fabric, usually cotton, that must be folded for use. This is the traditional or “old-fashioned” cloth diaper. Requires a cover to be waterproof.

Fitted Diaper –  A style of diaper that is contoured to fit baby like a disposable diaper with elastic around the legs and back. Usually made from cotton, hemp, or bamboo. Often secured with snaps or hook and loop, but some may require pins or another fastener. Requires a cover to be waterproof. (Examples: Mother-ease One Size Fitted Diapers, Omaïki Ö Sleep Fitted Diapers)

Hook and Loop – Generic name for Velcro or Aplix.

Hybrid – A type of AI2 diaper consisting of a waterproof outside layer and a disposable absorbent layer. (Example: Grovia shells with disposable Bio-Soaker Pads).

Hybrid Fitted – A fitted diaper made with a hidden layer of fleece inside to increase water-resistance. Requires a cover to be fully waterproof. (Example: Nic and Elli Hybrid Fitted Diapers, Sar n’dippa Dee Hybrid Fitted Diapers)

Hybrid fitted diapers use a hidden layer of fleece to increase water-resistance.

Liner – Thin layer of cellulose or fabric used to protect the inside of a diaper from poop. Liners may be disposable or reusable. (Examples: Bummis Bio-Soft Flushable Diaper Liners, Bummis Reusable Fleece Liners)

Cloth Diaper Liners

Cloth diaper liners come in disposable and reusable versions.

Longies – A soaker with long legs like a pair of pants, worn over a fitted, prefold, or flat diaper to prevent leaking.

Pocket Diaper – A style of diaper consisting of a waterproof cover with an opening inside in which users can put inserts to customize absorbency. (Examples: Sunbaby 4.0 Pocket Diaper, Rumparooz One Size Pocket Diaper, Ella Bella Ella’ssential Pocket Diapers)

Prefold Diaper – A style of diaper consisting of multiple layers of cotton or hemp sewn into a rectangle with the most layers placed in the middle. Requires a cover to be waterproof. (Examples: Bummis Organic Cotton Prefolds, Geffen Baby Hemp Prefolds)

How to pad fold a prefold cloth diaper.

This is the simplest way of using a prefold diaper.

PUL – Polyurethane Laminate – A compound material made by laminating polyurethane film to cloth fabric using chemical solvents. This waterproof fabric is used in covers, AIOs, AI2s, AI3s, and pocket diapers.

Sized – A style of diaper made to fit a specific size (e.g., small, medium, large). Users will need more than one size as baby grows. (Examples: AppleCheeks Envelope Covers, FuzziBunz Perfect Size Diapers)

Snappi – An alternative to safety pins for fastening flat, prefold, and some fitted diapers.

Snappi cloth diaper fastener

Snappi fasteners make prefolds and flat diapers much easier!

Soaker – A type of diaper cover usually made from wool or fleece (both fabrics are water resistant) that pull up over a flat, prefold, or fitted diaper. Soakers with long legs are called longies, soakers with short legs are shorties. (Examples: Disana Organic Wool Diaper Cover, sustainablebabyish Knit Wool Longies)

Shorties – A soaker with short legs worn over a flat, prefold, or fitted diaper to prevent leaking.

TPU – Thermoplastic Polyurethane – Similar to PUL, this waterproof fabric is made by laminating polyurethane film to cloth fabric using a heat bonding process.

Wrap – Another term for a diaper cover.
 

Cloth Diaper Resources

Diaper Pin: Diaper Pin is one of the oldest cloth diaper sites out there. Launched in May 2000, this is my go to site for diaper reviews. They also have reviews for sellers, forums, and a large buy/sale/trade board.

Padded Tush Stats: Tara at Padded Tush Stats collects reader reviews of individual diapers and analyzes the data according to factors like fit and absorbency, and by user characteristics like chubby or skinny legs, rash-prone, or heavy wetter.

Dirty Diaper Laundry’s Cloth Diaper Finder: This is a new resource and still a work in progress. I like that you can filter diapers in this database by price, diaper type, closure type, country of origin, WAHM or manufacturer, and several additional factors.

Diaper Swappers: One of the best known forums for buying, selling, and trading used diapers.

  • I used cloth diapers for 6 of my 7 children but mine were plain white without any wonderful coverings like one has today – mind that was 37 years ago and everyone was into using disposables at the time. Now of my 4 children who have their own children only one uses cloth diapers.

  • I’m using prefolds & covers mostly but am intrigued by all these other diapers. mostly for trimness- because some pants just don’t fit w. our bulky prefolds. though so far i haven’t found a good alternative that is trim but also as absorbent as the prefolds… though i am starting to check out hemp or just change my diapers more often if not using prefolds i guess is the other option.

    • You could also try using prefolds to stuff pocket diapers. Tons of absorbency plus the convenience of a pocket diaper make these one of my fave combos.

  • My son is almost 5 months old and I wish I would have cloth diapered him from the beginning. I am new to the cloth diaper world, so thanks for posting this! Totally clarifies what all the different terms mean.

  • I am pretty new to the cloth diapering, I did not do it with my first but really want to do it with my second. Thank you for describing what all the terms mean because it seems pretty confusing and intimidating with all those abbreviations.

  • There were a couple acronyms I hadn’t heard before! I am thinking about getting back into cloth diapering with more “modern” diapering supplies than the ones I bought in 2006! There have been a lot of improvements in cloth diapers since then!

  • This was very helpful. I was so confused with all the terms at first! We love cloth diapering!!

  • Thanks for compiling a glossary of diaper abbreviations. My granddaughter uses disposables most of the time as she only has 2 cloth ones that I won for her. I’m hoping my luck will hold out and I win another one.

  • I started cloth diapering my son when he was 6 moths (took me a while to get enough to be able to start) I had to hand wash for the first 6 months as i had no Washer/dryer! but it was worth it. my son is now almost two (next month) and we have a washer and dryer 🙂 I’m so glad we started, its a real eye opener of how much waste and toxins are really in disposables! Same with other stuff. Thanks to cloth diapers, we are now on the path to being more green. using cloth instead of paper(family cloth, mama cloth, unpaper towels) also using reusable straws and trying to switch plastic plates with eco friendly ones, same with my cats dish bowls!

  • Thank you so much for all of the definitions and helpful information. I am brand new to cloth diapers but I am really trying to learn as much as I can before my little one gets here. 🙂

  • wow this is definitely in or know how, because I didn’t know there was so much to learn about cloth diapering 🙂 thanks for taking the time to share with us ..@tisonlyme143

  • I did not use cloth with my first but am using it with my second. I am going to try and transition my 2 year old to cloth before he potty trains. I heard it helps them with potty training.

    • Yes, I’ve read this too. That kids potty train sooner because they can feel the wetness. My oldest had just turned three so that wasn’t the case for us, but that’s only one case. I hope it holds true for my youngest.

  • There’s a lot of info here I need to digest! Expecting my first in August, and my boyfriend is still unsure of using cloth. I’m hoping to show him it’s not so scary.

    • Congratulations, Stephanie! Best wishes for a safe and smooth delivery! (You could also try showing him how much money cloth diapers will save over disposables.)

      • All I had to do was google the cost of disposable diapers and do the math on a calculator to show my boyfriend how much diapers are and that changed his mind. I’m pregnant with my first baby and from the beginning I was all for cloth diapers. With the help of the internet shopping made everything even more cheaper and convent. For mothers who stay at home with their babies this is the way to go. Cost of cloth diapers pays for its self in two weeks of diapering your baby! Do the math!

  • Thanks for the glossary of diaper abbreviations,if its ok I would love to print them off for my friend,she s have a baby in October and would love to use only cloth

  • Bookmarked. I love how a list of terms and links to other helpful articles are listed right here in an easy to read format. No clutter, concise information. Thank you!

  • When I started baby sitting at 13 mothers were still using cloth diapers. By the time I was having babies cloth diapers weren’t heard of anymore. So when I heard that the cloth diapers were becoming popular again, I didn’t get it. I remember my mom telling me how easy I had it because I didn’t have to use cloth diapers. Anyway, now with grandchildren of my own, I have educated myself about cloth diapers. But I can’t get either one of my daughter’s to try the cloth diapers. No they won’t. I try to tell them. I will have a new grandson next week and I tried, but my daughter won’t hear of it.

    • Ah well, you tried. I remember what cloth diapers were like when I was a kid, and I’m so grateful for how far they’ve come since then. I know lots of mamas who changed their minds about cloth diapering later on after seeing how cute they are and how much cheaper they are than disposables. Congratulations on your new grandson!

  • even though I’ve been using my cloth for a few months, I’m thankful that you have a glossary to reference. Sometimes I get so confused! Thanks for the cheat sheet! I’m glad a chose cloth this time around!

  • With the price of disposable diapers these days it is a really good idea to start using cloth diapers (like I did a million years ago when I had my kids).

  • I always learn new things and discover new helpful sites when looking at different “cloth diaper 101” posts on different blogs. In this case, it’s Padded Tush Stats. I’ve poured over Diaper Pin. Some new review material is always great!

  • Price of disposable diapers these days is just crazy,I also wonder sometimes all thats in them scary really when you think about it,I think cloth is cheaper and safer

  • I em encouraging my daughter to use cloth diapers, but I find it somewhat overwhelming, so many different companies and products to choose from. Where does one begin? 🙂

    • I know it can be overwhelming to know where to start. I suggest checking out the Cloth Diaper Finder site where you can filter diapers by price, diaper type, closure type, country of origin, manufacturer, materials, etc. That can help you narrow it down. I always suggest trying several different kinds to see what works best – it can be a costly mistake to buy an entire stash of diapers before trying them first. It’s worth it though, and doing diaper research can even be fun!

  • This is sooooooo helpful! I’m new to cloth diapering and plan on starting this new adventure with my 2nd who is due in December, so having a run-down of all the abbreviations and terms helps a ton!! I also love the fact you list several other websites to check out for more information, reviews and other helpful tidbits!!

  • Thank you so much for posting all of this! Its so helpful! Plus, all my family and friends who are curious will be directed here as well. Sometimes I can’t describe all the types of diapers or accessories and people still look at me like I’m crazy for using cloth! Maybe this will help them understand what I’m talking about!

  • when the kdi were older we just had the dipaer and not the other thing and that great now with the new
    coming we goign to try these

  • I’m new to Cloth diapering and your post has educated me sooooo much! my mom does what she can but cloth diapering has changed so much since all my mom knows of diapering is prefolds and rubber diaper covers. Thank you!!!

  • I’ve been using this like a dictionary – I have it bookmarked and every time I read another post and I don’t understand something I come back to this 🙂 Thanks so much!!

  • I’ll have to make some flash cards for baby #2. Wish I knew this for my first born!
    Thanks for the great reference guide!

  • I love that you included this “tutorial”. My daughter is due in March 2015 and could sure use some help, other than Me standing over her telling her what to do!! Thanks so much!! 🙂

  • Thanks so much for the helpful guide!!! I have only been cloth diapering for 3 months and all the different abbreviations have been very overwhelming!!!!

  • Thank you so much for this! We are expecting our first in February and will be cloth diapering from the start. There is so much info and so many terms to wrap your head around, it’s kind of crazy. This post helps clarify things! 🙂

  • This is all SUPER good info for me. I am new to the world of cloth diapering. My daughter is 7 months old now and i am pretty grossed out by the amount of diapers we use. its pretty unbelievable. this page helps out a tun in my looking into cloth diapering!!

  • I used cloth diapers for my babies. I remember the Dr. Telling me on an check up “Now let’s see what kind of mother you are.’ “No diaper rash you are you a good mother” interesting hey. I also used a clothes line and another way they used to judge if you were a good mother was if your diapers were stained. Amazing hey. I used to poke my safety pins into a bar of soap to glide them through the diapers faster. Lots of reminiscing. I was a flat diaper must be folded for use. Yup had em piled up ready to go

  • I have another term: FST I saw this everywhere for a few weeks, then I bought some! (Flour Sack Towels) I got them at Walmart, “prepped” them and now I have no idea what to do with them. My wiggly baby doesn’t seem to want to cooperate with me when I’m trying to fold it and her bottom is bare. Any tips on how to fold & have them at the ready?

  • This is great info! I am overwhelmed by cloth diapers, being a first-time mom. This is helpful, especially the websites!

  • Wow! When I used cloth diapers many, many years ago, there was only two kinds

    pf diapers, and they homemade diapers made of flannel or bought diapers which were made of layers of a lighter cotton material. -There was no waterproof cover and pins were the fasteners. Many were the hand pricks I received pinning on diapers. They were frugal and cut down on diaper rash.

  • I am so grateful for the internet and people like you who are so willing to share their expertise (in this case regarding cloth diapers and all the accessories). It makes researching and decision-making much easier for people like me! Thank you 🙂
