Potty

I wonder how many times the word "potty" is searched in a library catalog. The reason I wonder is because I searched for it yesterday. Why, you ask? Because I was writing a paper and was curious about books about teaching your kid to go to the bathroom (aka "potty training" which is what I searched). Potty is normally not a word adults use, and yet there I was typing potty into a library catalog. Of course, the technical search term is "toilet training," but isn't "potty" much more fun?
