For those who asked, we live in Maryland. Mandates are on a county wide basis, so there are areas in the state that have different rules.
@TenLittleDinos, @Spottyspotladybird, there is a LOT wrong with the US, I agree. But mask mandates aren't one of those things.
The children are absolutely FINE - thriving, in fact, in large part because their time at their much loved nursery has continued uninterrupted through the pandemic. We have had NO Covid cases in the nursery and no closures (unlike my relatives the UK, whose nurseries and schools have been closed multiple times). All teachers and all parents are vaccinated (it's a condition of belonging to the nursery), everyone masks, and everyone tests if they travel outside the state. Together, these mandates have made a difference.
The amount of disinformation on this thread is horrifying. Honestly, what's the harm in a mask?
Multiple studies have shown masks reduce virus spread. As someone who knows multiple people who have died horrible deaths from Covid, I'll do anything I can to reduce the chance of spreading the virus to someone vulnerable.
