I've been using cloth diapers since Nora was about 1 month old. It's so hard in the beginning, especially with the number of times they poop! I'd definitely recommend stocking up on newborn disposable diapers. Even if you don't use them you can always return or donate them!
We used BumGenius newborn diapers for the first few months since Nora was so small. We use BumGenius 4.0 pocket diapers now. I'd totally recommend them (be sure to get the snaps!). They actually just released the 5.0s and the 4.0s are on major clearance right now with free shipping:

Also, congratulations to all of the new pregnant mamas! I rarely come on here, but I try to lurk this thread weekly!
