Saturday night we braved the mall to make a return, only to discover once we were there that we'd forgotten the stroller at home. Baby (toddler!) wearing to the rescue! I was glad I kept our carriers stashed in the car: Zao can only walk along with us for so long, and when - when, not if - he chooses to run off and investigate something, he is fast. Having some structure to corral him, and grant him respite once he's tired from walking/running, makes for an easier trip for everyone.
