We can't do "traditional" AIOs (i.e. those with PUL) b/c of breathability issues, but I recently discovered that we can do fleece AIOs. My current fave is the RB fleece shell set. They fit wonderfully, have beautiful contrasting fabric on the contour & liner, and are often embroidered or appliqued as well. And you can buy extra snap-ins for them. And for $.50 extra you can get a gender-specific "dream addition" (extra fabric in the soaker in the wet zone). Oh, and they make gorgeous WIOs too. Can you tell I love my RB shell sets? :LOL (BTW, I have pix of them in my stash pix).
