I'm not ashamed to let you all know that I've taught yet one more thing that is acceptable from a toddler, but probably not from anyone else. I've taught her to make dual thumbs-up, and to say, in a deep Fonzi voice, "Ey! Sit on it!". It's hilarious when she tries to do the deep voice. She ends up pursing her lips up big, like you see in the photo.
