Re: How many covers are needed for a NB stash full of prefolds/fitteds?
7-8. For DD2, I had 8 covers as I had gotten them on sale and I never ran out.
For the triplets, I had 15 at first. I noticed that 5 (each baby had a color) was not enough but rarely did one baby go through more than 7-8 in a single day.
