The cast is blue this time too.
There is a "closed fracture of the supracondylar humerus." In English, this means that he broke his left arm in the top bone somewhere right at the elbow. He was simply running around on the church playground and fell.
They didn't offer a water safe cast, so we've got to struggle through showers again. He hates all the attention but I think he's most upset that baseball is over for the season. Maybe the coach will make him a ball/bat boy at games.
