Shadows
OK, the picture is a bit blurry, but I think you can all see the problem here.  Eliot has recently discovered his shadow, and he is not at all a fan of this creature that follows him wherever he goes.  This is a photo that captures him frozen, for fear of the shadow getting closer.  Like a sheet of toilet paper stuck to your shoe, he just couldn't shake that shadow.  Never fear, mom was there to save the day!
