Sorry man but from how I hear you talking on this board I can’t help but think you are feeding that anxiety. I’m sure your children hear you complaints. There are plenty of different types of face coverings that can be used and I know at least at my school if kids do have moments where they need to take a mask break they can go outside and do so.
My daughter doesn't wear one. I bought her an ionizer which is way more effective and doesn't impede her inhaling enough O2 or exhaling CO2.
