I've got a lot of video of Caleb playing the piano and Eva does her fair share of awesomeness around here, too.
Here are some videos of her. This first one is her copying me. It is one of her favorite games lately. You should know that she LOVES peanut butter.
Here's another one of her. I heard her singing and playing the piano. I got out the Flip and taped her without her knowing. She is doing "Mississippi Hotdog". If you've ever done the Suzuki method, you should be familiar with this one...although she seems to take some creative license.
