   • 1998 May 21, KarCun, “Kooshies - tips needed”, in misc.kids‎^[2] (Usenet):

     "Those kinds of products have a waterproof backing. So when you put a male guard into a diaper, the, um, liquid can't flow into the padding of the diaper. Instead it just spills over the sides." This made sense. Dolly recommended a booster pad, which had no such backing, and therefore would provide the added absorbency I was seeking.
