A Visitor?

Tonight Jared is working over night, therefore, I'm home alone with Kathryn.  I was bathing her and everything was going as usual. She was splashing and having fun and then suddenly, her head jerks up and she starts babbling and pointing behind me.  I turned around and no one was there.  Then she stood up and starting waving enthusiastically at something with a big smile on her face.  Needless to say, it kinda freaked me out.  I've always been a firm believer that small children can see things we can't and I think that happened tonight. I wish I could've asked Kathryn who she was waving to.  My guess it was either Papa Dan or Grandma Peggy.
