The sad reality is that even before those symptoms appear they're already spreading it around, no? I totally agree that ideally, parents belong home with their parents, one on one...we certainly don't have the capabilities for one on one in our settings...nor the ability to get them medical care quickly should things worsen. But, with 4 boys of my own and only so many sick days to go around I can sure understand a parent's point of view. So, my policy is that if it's something that can be medicated by me and such medication allows them to function otherwise normally within the group, I'm ok with that.
