M.H.
I would suggest prefolds and wool. Wool is a natural fiber that breathes better than the polyester covers that a lot of people use (me included). I love wool. You only have to wash once a week, if that, and it never leaks. I use the Cloth-eez prefolds from www.greenmountaindiapers.com and they're great (I also get my Snappis there). I used pins when I started but now I use a Snappi because my boys are super skinny and I can get a tighter fit with the Snappi. I just use regular Tide to wash my diapers. Not quite to the 1 line. Use a lot of water and not a lot of detergent and you shouldn't have any stink issues. If you are worried about keeping the diapers clean you can use a liner (either flushable or reuseable).
It's early and that's all I can think of right now. I'll come back if I think of anything else. Or if you have any other questions feel free to pm me :o)
