I am a cm. My own dd came down with Chickenpox around 3 weeks ago, I contacted all parents let them know and tell them that dh would be keeping her away from the setting but it was their decision if they wanted to keep their children away, they all still came. Now one of mindees has come out with spots, I feel guilty but have another little boy today, seen as he will have already been infectious for a couple of weeks, must I exclude him?
