Yes, I have reduced the number of materials available each day.
We're currently spending almost all of our time outside, so the classroom is for naps, lunch, storage of toys that need to come out and an occasional art activity on a windy day
.
I wear a mask almost all day. The only exception is when I'm not very close to anyone outside. The children wear masks inside but typically take them off outside. Parents pick up and drop off outside in the driveway, if they get anywhere near me, they put on a mask.
I don't have any restrictions on their interactions or closeness.
I, honestly, do not spray down the outside equipment everyday. I do spray down toys that we bring outside (art materials, manipulatives, etc) each day.
I use a bleach water spray and lysol and clorox wipes.
I am currently full and haven't had to do interviews but I would probably have them physically tour the house then sit down outside with them if it was warm enough. I'd require a mask and would wear one myself.
