Made his own electric toothbrush

Matthew and I were brushing our teeth together yesterday morning, I with my Sonic Care brush and he with his kiddie manual brush. Normally I don't turn mine on when we're together (so he doesn't get jealous) but yesterday I felt like an extra-good cleaning so I did it. He stopped and watched me the whole time. Once I was done and he checked my teeth (we always inspect each other's work) he put his brush back in his mouth...and started humming. "Mmmmmmmmmmmmmmmmmm" as he's brushing back and forth! So perhaps we'll have to invest in some sort of battery operated toothbrush for him. Or maybe I'll just let him keep on humming cuz it's way too cute!
