What a lane does
A lane never changes the bones of a week. It adds one concrete tilt: the Builder takes the toy car apart at the pit stop; the Naturalist flips a log every day of bug week; the Athlete gets a relay in every block. At older stages the tilt gets bigger: the aspiring athlete's travel schedule, the future vet's shadow day.
You don't pick the lane; you answer one question
In the welcome wizard (and on your Family page) you tap up to three things your kid loves: balls & climbing, trucks & tools, the same book again, tea parties & saying hi, playing store. Each one points to a lane. Homie names the lane on the spot: the lane that comes up most wins, a tie goes to the first thing you tapped, and if you tap nothing they run Explorer, which is balanced and a perfectly good answer. Watch what they return to when nobody is directing them; that's what to tap.
If you already know
Open "already know their lane?" under the chips and pick it directly. The fifteen lanes sit in five worlds (Body & Outside, Hands & Making, Words & Ideas, People & Place, Spark) so the list scans in seconds.
Changing your mind
Tap different things or switch the lane anytime from your Family page. Nothing is lost; the week just tilts a different way starting Monday, and your growth profile will show you where they lean within a few weeks.
