Oxygen Please....

This is probably a totally inappropriate subject to broach but i was at the pediatricians office one day with my child when i overheard a conversation between a mother, and her daughter. Now your asking yourself, what is so abnormal about that. Well nothing, it was the topic that caught my attention. The daughter was about three years old, and was holding her private area and her comment to the mother was "mommy my who who hurts".........OK my first question is did she teach her child to call her vagina a "who who"? Exactly who sits around and thinks up these names? Do they have nothing better to do? Is there life on their planet? or oxygen?.........
