I am in the same boat as you. It is crazy to me that we accepted the risks of every other RSV, influenza, corona, rhino, rota, noro, and whatever other bug going around daycare every week prior to Mar 2020, and still do, but if a COVID 19 is detected, then the whole thing shuts down.
Every single one of those kids at drop-off and pickup has a runny nose. I am pretty sure we have an informal agreement amongst all the parents that no one gets their kid tested for COVID. It is one thing to do all this song and dance without an available vaccine, but it has been widely available for over a year.
