hey, continuity please..

The coolest thing (from the scientist in me).. there is this blue structure with a red button part in the center on Zoë's stroller, she was just checking it from both sides, trying to figure out why there wasn't a red button part on the inside... Looking at the outside, feeling it, looking at the inside, back and forth... she was looking for engineering continuity.. very smart girl ;) (proud mama moment).
