I was walking down the stairs today, carrying Leo to the living room for playtime/laptime. I slipped, and ended up falling to the bottom of the stairs. I lost my hold of Leo in the process. He looks like he fell 1 or 2 steps, but I'm worried that he might have hit his head on the railing. He is't moving much (this whole thing happened maybe 15 minutes ago), but that could just be shock, as he gets scared easily. When he does move, he isn't limping or anything. Help?
