AWW dont beat yourself up over this...It was an accident, just a freak thing. He probably loves playing this game with you! Yoda was in my lap one night and daddy came home...My favorite thing to say to him is "daddy's home" and he will run for the door. Well when jumping out of my lap he hit his head on the edge of my desk and let out a very loud cry. We still play the daddy's home game but I just make sure he wont hit the edge of the desk now....It really is not your fault...freak things happen all of the time. You reacted quickly and he knows your heart is full of love for him!
