Invite a grandparent, nanny, or anyone else who should see (but not edit) your family's activity calendar — on a paid plan, from the Followers page.
Once you're following at least one family, your sidebar switches to a dedicated follower view — separate from the "Schedules" and "Enrollments" tools that only make sense for your own kids' calendar.
This Week shows an aggregate calendar with events from every family you follow merged onto one grid, so you don't have to check each family separately. Under Viewing in the sidebar, a switcher lists "All families" alongside each family you follow by name — pick "All families" to see the combined calendar, or pick one family to jump straight to that family's own calendar instead.
