I'm okay with that. Think it's dumb but it's your school, not mine. My 3-year-old's preschool requires masks and it's fine. Was a bit of an adjustment (they were not required to wear one last year, as 2's) but over the first 2 weeks of school you can see the whole class going from 1 little girl who wore one last year (even though not required) to about half the class wearing them at the start of this year, to everyone just doing it automatically. My kid will even ask for his mask if we're going out to the playground now.
