The vital stats:
Lu weighs 36.5 pounds.
She is 40-some-odd inches tall (Jason has a hard time remembering numbers and gossip). Well on her way to being 5'6" — which is pretty dang tall considering her parents.
She can hear everything (it turns out she has just been ignoring us).
She has 20/30 and 20/40 vision.
She got three shots, and she was really brave. While they didn't cover any specific developmental milestones at the check-up, I feel sure that whatever deals she is able to maneuver as a result of "being brave" will be proof of her mental fitness.
