Here's a video of Ava crawling around the kitchen, and eventually attacking a kitty. I had to intercede at the end. Mia handles it very well usually; but a couple minutes after I filmed this Ava got a hold of Mia again and ended up getting bit on the hand. Nothing major, just a little natural consequence. She seemed more confused than hurt, and it hasn't stopped her from the going after the kitties again and again.
Here's a more recent video of Ava clapping! I've been waiting a long time for her to figure out how to do it and all of a sudden she got it! Now she does it all the time (probably because Mommy and Daddy react with such excitement). It's pretty stinkin' cute.
