Do the route together once.
Walk it side by side, noting crossings and the house itself. Then let them lead the second time.
Let the arrival speak.

A quick message between parents about timing and pickup keeps everyone on the same page.
Honest limits.
Indoors, a location can be approximate or delayed. If something looks unexpected, call — that’s what the plan is for.
