Wow you have families that are fantastic then. I can't convince any of the families I have to stay home for an hour with their sick kid let alone until they get better...and even when they do take a day they complain to me about having to pay for the day when they didn't send their kid. I too, let them come with colds, but I find too many parents are medicating in the mornings with tylenol and then hoping I don't notice the green snot and fevers...by the time the fever comes back they have been here infecting all the others for hours...or they tell me the green snot is normal and that they have been checked by a dr. which i don't believe but feel bad asking for dr's notes as most have to pay for them now...such a frustrating time of year for sure with illnesses.
