No one needs masks anywhere, except perhaps those currently symptomatic and needing to travel in public to access treatment.
Children certainly don't:
"Distancing, hybrid models, classroom barriers, HEPA filters, and, most notably, requiring student masking were each found to not have a statistically significant benefit"
Its possible that the lack of regular human contact and connection (including not being able to see people's faces) is having seriously negative cognitive and development impacts on children; https://www.bmj.com/content/374/bmj.n2031
There isn’t a lot of physical distancing at any school playground that I’ve seen. “CDC recommends that people who are not fully vaccinated wear a mask in crowded outdoor settings or during activities that involve sustained close contact with other people.” https://www.cdc.gov/coronavirus/2019-ncov/community/schools-...
