Sending your child to a school where you don't know or control what other families are doing or not doing always entails some risk. Especially a child of an age where they cannot be vaccinated. My youngest is too young for the vaccine, and has asthma that lands him in the ER usually several times when he contracts an upper respiratory infection (except for last year, which means honestly I'm considering having him mask up for flu season even when they're no longer required in my area). I know people who have gotten covid even though they're vaxed, who have children the same age as my youngest.
And so we did sit down and weigh our options when it came time for sending him to in person school. Ultimately we decided that it was better for him educationally and for mental health reasons for him to go to in person school, masked, with covid-19 protocols practiced by the kids. We absolutely believe there are people who will send their infected kids to school (it's already happened a few times in the district, because the parents didn't want to be discriminated against for their kid having covid). We believe it's very likely that there will be asymptomatic kids in his classroom (or he may be one at some point). The only way to control the situation is to have him be home with me quitting my job and forbidding our college age kids from being in the house with us. Maybe if we were caring for an elder relative on immunosuppresive therapy, we would do that, or if there was some other situation. I think there are some families that would choose to do that in our situation and think we are horrible people for not.
It's just a part of life. Whenever we go get medical care now, we're weighing the risk of exposure. Going to an outdoor gathering or not. Going into the store if I forget to order our stuff for curbside pickup.
We shouldn't be putting yet another burden on medical staff than they already have. Do I think it's fair my fat, middle aged ass in a triage situation probably would be put behind the 25 year old healthy fit mom with 3 little kids but who also is a rabid covid anti-vaxxer and anti-mask activist, if there was only 1 ventilator between us? No, but I accept that's the reality.
