It absolutely baffles me that the same people who freak out about the possibility of there being germs on their kid's pacifier will wipe up poop with a wet wipe and send the kid on their way.
Even as an adult, I don't get how people think of toilet paper as having any "cleaning" power. It just seems wildly unsanitary if you bother to think about it, which is why I suppose most people choose not to.
