Have you brushed your teeth?

Sophia started to brush her teeth since I first showed her how to a few months ago. She loves it ever since. If I forget or is too lazy to let her brush her teeth she will sure remind me. And she also requires me to brush with her, if I pretend she will point out and say "mama".
However Sophia's brushing teeth is basically eating tooth paste which has a very pleasent flavor. Brush is just her teether and gets worn out very quickly. She started to figure out how to wash her mouth a few weeks ago and really enjoys it a lot. When she thinks she's done she will hand me her brush, wash her mouth, wipe her face, and say "bye" to the "Sophia" in the mirror.
