Just a comment, my 4 year old son was sick about 6months ago with the runs, and I got real tired of cleaning out his underpants so I bought him a package of pull-ups, in a hurry I accidentally bought the large pack, we only used two of them so now i have a full package in the top of his closet! My 6 year old daughter now is sick with the runs and she is now wearing them. She has had a lot of soiled underpants as well. Save the laundry.
