I wanted to have some one size diapers in my stash (especially for when Andrew outgrows his small Charlie Banana's). I ordered a couple of Bumgenius and one Oh Katy. I like the Bumgenius, I think they work great. They are a bit bulkier than a sized diaper, which is expected. I do find it a little harder to stuff (when you put the insert inside the diaper cover) than the Charlie Bananas, the same with the Oh Katy's, I think it's because of the extra snaps that make them a one size diaper.
(Bumgenius, Charlie Banana One Size, detail of leg elastic and an Oh Katy)
The Bumgenius come with a regular insert (it has snaps to adjust the size) and a newborn insert (a thin insert). The Oh Katy comes with the same inserts as the Bumgenius. The sized Charlie Banana's come with 2 normal inserts. It's nice having extra inserts for when some are still drying or when I want to put them in other diaper covers.
I wanted to try the Oh Katy because it also has the insert opening in the front, just like the Charlie Banana. I want to have the option of using the disposable insert. The Oh Katy also folds up nicely (wrap n' snap, like it says on their website). I thought the snaps on the Oh Katy were weird, or it just looks weird on Andrew right now. I liked the Bumgenius better over the Oh Katy, I will still use it though because it works just fine, I'm just ocd about how it looks, lol
The last one size diaper I tried was the Charlie Banana. The only thing that kept me from ordering this one before was that, the one size diapers have an adjustable leg elastic, I didn't feel like messing with an extra step. I guess it isn't a big deal since you adjust only once, until the baby gets bigger, then you re-adjust. I have only used it a few times, but I think it also looks a little weird, I'm so picky!
In conclusion, all the pocket diapers I bought work great! I think I do want to be able to use the disposable insert, so maybe I will have a few Charlie Banana's or Oh Katy, I haven't decided which one I like better. With the Oh Katy I don't have to mess with the leg elastic, but I think Charlie Banana has better colors, we'll see... Since working on these 2 cloth diaper posts though, I feel like I have gotten more leaks with the Charlie Bananas :(
My stash will consist mostly of Bumgenius, I feel like they stay dryer. So far I have: 6 small and 1 one size Charlie Banana, 1 Oh Katy and 8 Bumgenius (they had a sale going on, so I bought 6). I love looking at all of them together, so colorful :) Feel free to ask any questions. Cloth diapering seems so overwhelming at first, but once you start, it's actually really easy.
