I left my child home last week due to a horrible cough...we received letters from the school nurse staten "keep your children home if any certain symptoms may occur or not feeling well please" so this is what I did. My child went back to school for 3 days and came back home really sick this time. Now maybe I'm over reacting, but don't you say, "close the school for a few days" We get are children feeling better and then they come home feeling worse after they go back. I'm not the only on that has had this happen.. I take this stuff serious! And to sanitize and clean the school really good I think is a great thought!
