Is this thing on?

Sophie is the master of all things electronic. Give her any toy and within seconds she'll have it powered on and making noise. More incredible is that when she's finished she'll turn it off. I'm still pretty impressed by this feat but in the eyes of a toddler it makes sense. It is just one more button to press. When all your life is about mashing buttons to see what they'll do one button is as useful as any other.
