We're a big fan of Knickernappies! I've used them for both kids and love them even more now than I did with my first child. These are well made diapers that last a long time. I've never had an issue with the snaps or elastic. And somehow even the white fleece stays looking white. I've had some staining, but it goes away after just a few washes, which is great. I originally started with the sized diapers, and do like them a bit better, but the OS are a great option. They have seem to fit a very wide range of kids. My kids are skinny, but I know other moms who use these on chunky babies. For a OS diaper they are quite trim as well. I also love the Loopy Do inserts that come with these diapers. I love the stretchy sides and the fact that they're a side snapping diaper. Stuffing the inserts is so much easier with the new KND design that is a bit wider than previous versions of this diaper. The only thing I'd like to see change is a wider variety of colors and colored inners.
