I'm planning to use a local diaper service for a weekly drop-off/pick-up of prefold diapers (graciously gifted by my in-laws). I know I'll need a stash of diaper covers for the prefolds and I have started to add some to my registry as well as pick up a few myself. We plan on cloth diapering from the hospital onward, and using them when baby goes to daycare as well, so I know I'll need extras to send with baby each morning.
I'm wondering how many covers I will need in my stash? AND how many covers per size - newborn, medium, large, etc?
