My 8 year old DS2 just got over a nasty virus last week-- fever up to 104, nonstop cough, chills, headache, runny nose, etc. I treated him the same as always and had no plan of taking him to the doctor since he was improving by day 3 (fever was highest on day 2), but if you miss 3 days of school you have to get a doctor's note to return so I had to take him in. He tested negative for the flu and the doctor said to just continue what I was doing at home. He ended up missing 4 days of school and then we had a 3 day weekend.
