Poor, poor baby. He decided to climb up on the girls' dresser, presumably to look at himself in the mirror. Nobody saw the actual fall, but he must have taken a step backwards off the dresser and fallen pretty hard on his right leg. There was not an obvious break on the x-ray, but he can't put any weight on the leg and won't even crawl at this point. He looks so sad. Tigger lost his bounce...

(yes, that is a bit of oatmeal from breakfast on the splint)
