I received this as a bonus for introducing a friend to Kodomo Challenge. I thought I would use it for my child, but I forgot I had it and it turned up while I was cleaning. It seems to be designed so that if you wear it over underwear, it will prevent the bed from getting wet. I haven't confirmed the actual item since it's unopened, but according to the Kodomo Challenge website, it's shaped like a wrap-around towel. Would this be suitable for children who are currently potty training?
