Training for the marathon

At today's doctor appointment, I got hooked up to a machine to measure my heart and movement. The doctor said "looks gorgeous". Since then, I've been working out in Mommy's belly to keep up the good work. I think Mommy would prefer that I relax a bit but a girl's got to keep in shape, right? Besides, I need to prep for a future Baltimore marathon like my Aunt Sarah and Miss Amanda.
