"Whoa!"

In the last couple weeks, Kate has started saying "Whoa!" and "Wow!" all the time. It's hilarious. For example, this morning, I gave her a big ball to play with and she said, "Ball!" "Yes, Kate, that's right! That's a ball!" Then she proceeded to throw, kick and roll the ball around the room, chasing it and saying "Whoa!" over and over.
