A child at school is being treated for a very serious illness and all the parents have been sent a letter asking for their children to be 100% well before coming into school so as not to pass on an infection. My DS is someone who is generally healthy but has the normal run of colds and more than the normal amount of snail trails. He has a cold at the moment, which is fine as it's half term, but what would you do next week when he has to go back to school if he's almost completely better. He loves his school and I'm loathe to take him out and would find it impossible to HE as I work from home. I feel desperately sad for this child and the family. I genuinely don't know what to do as most of the time DS goes into school with a runny nose and a bit of a sniffle in the winter months.
