strange fascination with running water

So, I have this sweet little girl who has this strange fascination with putting her hands in running water. Today was one of those days where she just couldn't get enough! I often will find that she is "missing in action" and go to find her in my bathroom playing in the water. (I'm now locking the door, but I often forget, and she knows!) She also enjoys putting her hands in the sink when I'm doing the dishes, just to get her hands in the water. Earlier today, I noticed that Austin was chewing on one of the books. I walked out of the room for a moment and then I heard her running down the hall, but didn't think much of it. A couple of minutes later, I didn't hear anything and I found her (again) back in the bathroom "washing off" the book. It was soaking wet! I tried to just remember, she was trying to help her mommy by washing off Austin's slobber.

These pictures I've posted are actually from a few days ago when I caught her in my bathroom making a mess. I walked in to find her playing in the water and she just looks at me and says, "Wash, mommy, wash." At least she's learning good hygiene.
