B’H our shul has the use of preschool classrooms for babysitting on Rosh Hashana and Yom Kippur, which means the kids have plenty to play with, but it can get chaotic having 20+ 2-6 year olds free playing for several hours. I’ve tried to think of activities we can arrange but am stumped on YT-friendly activites. Need free or cheap and no food to bring in.
