That's great that he hasn't been sick in quite a bit! Whatever would help you to calm down is what you should do. Would just having one child home help or would it be helpful to ask your mother in law to just come and be there for emotional support? In the meantime, put on a movie that everyone likes and remember that in a few days this will be far behind you. Little kids with sickness is such a drag, but they also recover fast, hopefully he's done with it and so are you!!!
