My daughter is 2 weeks old, and we've been using Kissaluv 0's with mostly Bummi SWW covers. I love these diapers, they are really easy to use, but might not be the best choice on a budget - even if you get seconds they're about $80 per dozen. We go through about 16 diapers per day (bf poop!) right now.
Prefolds can be a little intimidating to the newbie, but they can't be beat for price. Could you offer your help on teaching folds and other tips so they don't get discouraged and give up right away?
