I know just how you feel.

Everyone has bad days.  Sometimes, all you want to do is have a good cry and curl up in a quiet place.    And when you're two, well, sometimes there's just not much you can do about it.  Sometimes the best thing you can do is call it quits and start over another day.   I had a shoot a week or two ago, where this was the situation.  She was as cute as a bug, but she just DID NOT want to be photographed.  She would be fine, until I picked up the camera.  And then, well, you can see for yourself.  She was so happy when she was walking out the door.  We'll try again soon.  :)
