Considering this question as DD4 goes into her PGCE year! How many would masks your DC need for travelling around the site on an average school day? DS4 calculates that for many, bus to school, to form, to first lesson, to second lesson, to break, from break, to third lesson, to lunch, to fourth, to final class and then on the bus home means that some DC could end up needing 11 masks. Obviously disposable ones are bad for the planet, and also, how will DC store so many?
I’m very pro-mask, but realise many DC will reuse used ones, possibly making the risk worse- how would/will your DC prepare?
