We have 2 days worth of good useable nappies and probably a third day of "make do" nappies. It sounds like a lot but we actually don't go through that many nappies - probably about 6 a day. I previously thought we would use heaps more than this! We bought most of our nappies on sale which was great costwise but the colours aren't as cute as others. Our workhorse nappies are the BBH petites and when DD is between sizes we just snap to the looser size and use a cover.
