Lest I fail to convey this by other means, Katherine is a delight. And I say this after a week of teething trouble. She is, in general, a very active, happy, sturdy little kid. She loves to run for trouble (crawl speed doubles when she spies a piece of paper on the floor), and she shrieks with laughter if she hears you coming after her. Without fail, just as you go to grab her, she turns and grants you a beatific smile.
She also stares intently at other people now, eliciting a lot of attention even from non-baby people. When we stood in line at the DMV the other day I found that a number of gruff-looking guys were holding conversations with her and making faces at her as she enjoyed a ride on my back.
