What would be a range of costs to supply yourself with diapers for the first time? I'm sure it varies a lot. Say you did all prefolds with simple covers? How many do you know how to get in each size?
2 dozen newborn or infant prefold, about $20/doz
5 small covers, Proraps ($7.25), BSWWs ($12.50), or Litewraps ($8)
2 Snappis ($3 each)
pail liner (~$15)
That will get you going for about $100-$125. I personally could not have made it without two pail liners and pocket diapers for my lazier moments. You will probably wash diapers every other day.
