Kim writes of the progress her granddaughter Ava is making:
"Ava loves to toddle on the sidewalk, all the way to the end-turn around-and do it all over again. Unfortunately, the poor baby doesn't dare to look down while walking. It makes me sad that she gets stuck on a benign crack in the sidewalk. She gets visibly agitated and cries. It's a simple fix. Pick her up, move her past the crack, and she's good to go. Visuospatial issues, indeed. And what missing gene is responsible for my granddaughter having to walk as carefully as someone who is 80 years old?"
