This is what Traci has referred to as Kylie's "reflexive pose". This will change after 3 months of age. We have several photos of her in the same pose.
Your source for brilliant ramblings and other minutia.
Here Kylie is enjoying the background music and dad's attempt at singing.
The next American Idol? Prior to snapping the photo, she was making cooing noises into the microphone. We had some music in the background that she was enjoying. Shortly after trying to get her to do it some more she burst out into a crying fit... which I was able to capture. I'll post that for you to listen to soon.

This is Multnomah Falls. It's supposed to have the largest drop of any watefall in the US, maybe North America too?
