Do you have a son or daughter who is a night-time bedwetter? I put paper pants on my son at nighttime just for insurance! He does pretty well at night, but that one night in twenty that he dreams he's in the bathroom, oops!
How about a free sample of the new night time paper pants called UnderJams? They come from the makers of Pampers. Just tell them what size you need and your mailing info. Usually, but not always, these free sample deals will have coupons in them too, so that's an extra bonus.
