Hi Joyce, I am also a director and owner of my preschool. I have supplied my teachers with all 3 options to wear; regular mask, clear mask and shields. The clear mask at times do fog up but shields are great. Although most of my teachers are wearing their masks all day.
All of my students adapted great with teachers wearing masks. They were already seeing mom and dad wear them out, so it wasn't scary at all.
As for taking their temperature, we do every morning and it's not a "gun " looking one so it wouldn't frighten the kiddos either.
Most importantly I have the parent take their temperature before leaving the house, so we aren't the ones taking their temp at the door and have to turn kids away. I think that would be more devastating to them. we take it during our washing hands for snack and again before lunch. The kids are so quick to adapt and it's a part of our daily routine now.
Comfort the parent, let her know this is the nee normal and all preschools are doing. Again don't get a thermometer that looks like a gun.😉Have a blessed year!
