Door edge - 1, Ronan's forehead - 0
It's usually not much of a problem as far as he's concerned, as Ronan does not mind falling, stepping on things, or bumping into walls. It turns out he *does* mind running forehead-first into the edge of an open door. The doors in his room are impressive - sturdy and large. They are also unyielding and unforgiving, especially when hit directly on-axis through the hinges. I did not see the impact but I heard it - a loud, ominous thump, a few moments of silence, and then Ronan's angry, pain-filled cry.
He looks cuddly and subdued with his Happy here, but put a ball in front of him and watch him go berzerk
The outcome is not nearly as bad it could have been - there was relatively little blood and Ronan never lost consciousness - but he grew a nice little hematoma that will most likely become a tough looking black eye tomorrow. I had hoped the pain would have taught Ronan a lesson, one about the consequences of being recklessness, but after bath he was right back at it, kicking the globe and crashing into things. Sigh. I've resigned to simply be exceedingly grateful for decent health insurance.
