Last night JD and I had a huge discussion of the plural form of the word tooth following this comment:
"Well, Mommy, I'm going to go downstairs and brush my tooth."
"You mean teeth, Jacob."
"No, I mean tooth."
I explained that tooth was, well, one tooth and teeth referred to all of them. We discussed mouse versus mice and I was really pretty confident that at the tender age of four, he grasped the concept!
Downstairs we go.
"Oh Mommy, now I can't find my toothbrush. Wait, I mean my teethbrush!"
Why is the English language so confusing to little people?!
