Custom Child/Infant Pricing for Direct Bookings

It would be great to have the ability to set custom pricing for children on Direct bookings.

For example, hosts could define an age threshold (e.g., under 12) and assign a custom rate, including $0/night, while guests above that age automatically follow the listing's standard extra guest pricing.

This would make Direct bookings much more flexible for family-friendly properties. Currently, the only workaround is to manually adjust the booking price before sending it to the guest, which doesn't work for instant bookings made directly through a host's website.

Adding child-specific pricing would bring Direct bookings closer to the flexibility offered by many OTAs and make the experience much smoother for both hosts and guests.
