Here are a ton of videos of Sienna, taken when I tried to get her to say her two new words, "Gonk!" and "tickle tickle". The first one is a little compilation of the best parts, so if you don't feel like watching 6 baby videos, just watch that one. If you don't feel like watching any baby videos, you are in the wrong place.
