Hey! Something I can talk about...kind of.
I just switched to cloth for our 9 month old. I've been using Bum Genius AIO and the Bum Genius One Size. I also have a Fuzzi Bunz, some Thirsties Fab Fitted and a Crickett's hemp.
So far, I like them all, but I am leaning more toward the AIOs because they are so easy (and thus, Daddy-friendly). The complaint many people seem to have is that they take too long to dry. Since I have so many to cycle through, the additional drying time for the AIOs isn't a big deal.
I like the Crickett's for nap time because they are very absorbent, but also quite bulky.
The Thirsties are super soft, but require a cover (although the just came out with an AIO that I haven't tried) and they are bulkier than the AIOs and FBs.
Since the pocket styles are supposed to be better for heavy wetters--because you can add more layers--I may like those better as the WeeOne gets older.
