I loved the sized BG AIOs. They were a great diaper to introduce to our daycare since they are so much like a disposable. Loved the fit, trimness, ease of use, etc.
But,we got stink after awhile. I stripped, sunned, bleached, and added more detergent, but it kept coming back. Even would turn them inside out and wash for a deep clean, but couldn't keep them clean and it was too much work.
Switched to mostly BGEs and haven't had cleaning issues since. Although I'm tempted to try some large Simplexes now that she's outgrowing the rise on the BGEs.
Would love to see Cottonbabies do a sized AIO again.
