My heart goes out to parents of young (& "young-ish") children during this pandemic

How do you tell a seven-year-old that they can't have a birthday party?  What happens if that Bar/Bat Mitzvah celebration has to be held by livestream and even the grandparents can't attend?  If I could figure out how to help, I would, but I'm so tech-challenged that I can't even figure out how to set up a Zoom meeting and pay a video visit, and being probably as old as the grandparents (and therefore, in the high-risk category), I certainly can't pay a *real* visit.  So sad.  :(
