I would like to reduce the financial "hit" as much as possible after the birth of our son and want to start purchasing disposable diapers now in a variety of sizes, brands. Did anyone do this with previous children? How many of each size did you/are you purchasing? I am only purchasing size 1, 2, and 3's right now (staying away from newborn sizes as our hospital will provide a box for us to take home-if he's even that small!). Did you spread out amongst brands or choose one brand/type to stay with? Just want to make sure I do this as intelligently as possible during the next 10 weeks!
