I came late to this but...When I think of the Holy day rituals, especially the high holy days and sacred time..I think of Kabuki plays https://en.wikipedia.org/wiki/Kabuki_dance and the festive ceremonies such as Up Helly-Aa https://www.youtube.com/watch?v=qR7uiGVK0sQ where re-enactment of an event happens. In these situations, specific worshippers are not always required if specific cult members are missing, represented instead by mask wearing members of the clan/tribe/cult.
As to including children, i have included them in the past, as a facet of their education, with guidance from their peers. Just my 2 cents worth
