On a related note, for volunteers, I saw they had been doing child badge limitations as well. The 2018 Volunteer packet had added a "Children" section on page 9 of the packet, which further limited the adult volunteer to bringing only one child, aged 12 or under, with them. (No work by the child at the site, parent or legal guardian only.)
Last year, a father was replacing his lost childrens' badges, so was definitely more than one last year, for volunteers.
