My son is 7, he attends private school. His CF is progressing and I need to shield him from the winter cold/flu/virus pool as much as possible. How can I approach letting his peers/classmate parents know he has CF and could they think twice about sending their kids to school with a non allergy caugh, colored mucus or a low grade fever. I fully understand that parents have work and often can't take time off. I wonder if a simple "carefully" crafted note to his classmates parents should be distributed about sending their child to class sick or to ask their child to shield their cough/sneeze from my son. The balance is finding a way to protect my sons lungs while not putting people off and worse yet...having kids be instructed to stay away from my son. Any advice is much appreciated 8^)
