These covers are meant specifically for nighttime use. If you are going with the Wool Soaker, one cover will usually suffice, but two is even better since they do need to be line dried and this can take up to a whole day. Plan on getting at least three night covers if you are going with polar fleece covers, and doing your diaper wash every couple of days.

* An important note on Wool soakers: Wool soakers are not meant to be water proof. Wool naturally absorbs and holds up to three times its weight in moisture. The natural lanolin in wool neutralizes the smell of urine naturally - when you wash wool, you will need to use special lanolin soap.
