I recently headed into the bathroom at my sister's house, immediately after one of her kids exited the room.
As I turned the door handle I received the following warning. "Aunt Clownface, I wouldn't go in there right away. I just did some #2 and #3."
"#3? What is #3?" I asked.
"Diarrhea. You know, #1 and #2 mixed together."
Deep breath. "Uh, diarrhea isn't #1 and #2 mixed together." Then I explained what diarrhea is.
Affronted the child responded, "THAT'S what diarrhea is? How come no one ever told me?"
One of my sisters used to carry a very tiny chip on her shoulder that our mom never "taught her that she needed to rinse conditioner out of her hair." My mom claims that she didn't want to point out my sister's greasy hair (which was made so by the unrinsed hair conditioner coating it) for fear of making her feel bad about what my mom thought was an unfortunate, temporary and unavoidable aspect of puberty.
Hearing my niece complain about never having been told what diarrhea is made up of reminds me that you can never predict what your child "needs" to know in order to live a fully informed life.
Good luck parents.
