Several kids, or kids from different orders

Several kids on one order: upload it once. We add every kid the order covers.

Adding a sibling later: on that kid's order step, tap Same order as your other kid. It reuses the order with no new upload and nothing extra used from your plan.

Kids from another order (stepkids, or a kid with a different parent): when the first order is done, Kidnights asks Kids from another order? Scan that order the same way, or set the kid up by hand.

On your family page, every row shows which kids it's about, and Plan a trip finds the nights when all of them are with you, or all of them are away.
