Blueberry Diapers logo One-Size Simplex All-In-One Diaper cotton or stay -dry inner built-in choice. Made in USA.

The diaper has pocket openings on both ends that allows you to increase the diaper's absorbency by adding extra inserts (also called doublers).  This also enables any extra stuffed-in doubler or insert to agitate itself out in the wash. (Note from Karen: in theory should but it might not depending on your machine and the contents of the particular washload. Even so, they wash quite well for an all-in-one style diaper.) Half of the soaker pad is attached, while the other half also comes out through one of the pocket openings during the washing cycle. 

 It is made with a waterproof outer layer and 10 layers of 100% cotton birdseye fabric in the wet zone and one side of the flap has stay-dry fabric.

inside an organic diaper
The unique thing about this diaper is that it has an attached stay-dry microfleece layer on the soaker pad that will keep your baby's bottom dry. To use this feature, simply pull out the other half of the attached soaker pad and lay it over the body of the diaper.
organic cotton diaper inside
If you prefer all natural fabrics touching your baby's skin, simply keep the unattached portion of the soaker pad tucked inside the pocket. This way the stay-dry part of the soaker is tucked inside and only cotton touches baby in the wet zone.


on 14 pound baby on a 13 pound 10 ounce baby. The fit is snug to the body. It doesn't sag and it is not poofy.

One of my favorites!

I love how trim this diaper is! It fits great and is really absorbent, I've never had a leak. I also really like the fleece option. I always put a fleece liner in my diapers anyway, so it's nice that I don't have to add an extra piece to this diaper. I haven't used the pocket feature yet because I really haven't needed it, but I love that I can easily add absorbency if I want to. Pretty much the only thing I'm not a fan of is the tag is right on the edge of the diaper. I don't really think it bothers my LO, but it just doesn't seem like the most comfortable thing when she's wiggling and her little tummy hangs over the edge of the diaper right there. I think I prefer the other design that has the thicker seam around the edge.

Super soft

I love blueberry! They fit both my littles great. Trim, beautiful prints and absorbent. These all in one organic versions are super soft. Highly recommend!

prefer a prefold with a cover

I reluctantly bought these (TOO EXPENSIVE FOR ME!) mostly because of the RAVE all over the internet. When I got my Blueberry AIO’s, I wasn’t super impressed. The outer fabric just wasn’t as AMAZING as I had expected it to be plus the cost is probably is what ultimately drove me to return these diapers. Yes, they would make for a quicker change but I hear they take forever to dry and I’m not hot on the fact that I would have to dry the PUL portion of the diaper in the dryer (since it’s an AIO) so often and for so long. As always, the organic cotton got me excited but to me, what’s the difference in this or an organic cotton prefold with a cover! I still get my precious organic cotton, I don’t have to beat up my PUL covers and they dry time is fast!

Awesome diapers!

These diapers are awesome. We bought them for our big 8 week old when he outgrew his others. They fit great, no leaks, and even work for overnight with an added GMD prefold in the pocket.

Amazed with this product

I had a whole stash of AIOs from another brand that I was fine with. They leaked after an hour or 2 but I figured that was normal and I had no hard feelings towards them. I then lost my ENTIRE stash of diapers because someone accidentally threw them away (long story)... so since I had to rebuild my stash and didn't want to order from seperate websites (I refuse to try another brand of prefolds so I was stuck with GMD for my entire order lol) I decided to try blueberries instead of my previous AIO brand and WHAT THE HECK. First of all there's a cotton flap with stay dry material on one side so I'm able to keep the wetness away from his skin. Second, it's been 4 hours and he still hasn't leaked. I don't recommend leaving your baby in a diaper for this long btw, I'm just trying to see how long they'll last and this is incredible. I also love the material and the fit is great. I absolutely love these diapers and can't believe I used anything else for so long. I was really skeptical over these for some reason, probably because the leg elastic looks weird. But I'm way more than happy with these.
