Children should be protected against airborne transmittable sickness.
Also, we are still in COVID it's not over.
Two year old children will remove their facemask to pick their nose, or share a licked cookie with their best friend. You can try to teach older kids to use a facemask corectly, but for two years olld it's security theater.
COVID is around, and always will be. And "protecting" causes more harm and weakens the development of the immune system.
All well known and common sense stuff, to those who don't live in fear of merely getting sick.
That risk elicits a disproportionate response in rational people. Dismissing it is useless.
Guess what prevented me from getting sick last time I was in the car with my father just days before he tested positive? I was wearing a mask.
Mask and get your vaccines and boosters and limit exposure. For everyone!
