I did an interview last week.
I have also been open the entire time, though. I took everyone's temps before entry and had them take the paperwork home to complete and return. I am not high-risk, though.
Maybe you could just require the adults to wear masks and not allow their children to touch anything other than one or two items that you have them drop in a bin for disinfecting?
At least until you know for sure you will be enrolling?
