Michael the Mountain Climber

So I have an expert mountian climber on my hands. ok so bunk bed climber is more like it. He thinks he is invinsible. Today he fell off the bunk bed for the first time. He held his arm and shoulder most of the afternoon so we took him in and he decieded that he was just fine. He was and now he is just fine. I aways am wanting to be safe rather than sorry.
