A "swish-swish" moment...

This morning my five year old was complaining about having to use "swish-swish" (actually called a fluoride rinse) after she brushed her teeth. "But Mom...why do I have to do "swish-swish" every morning? (in a very whining voice, mind you...) "Because if you don't take care of your teeth they may fall out." I said. She paused for a moment. "But Mom...(whining again), all my teeth ARE going to fall out." O.k., she got me there.
