Hi. I missed about 12 weeks of school each year from the sixth grade until I finished high school. If your child attends public school, they must offer a home school teacher if you request it. Talk to the staff at your child's school even before school starts and let them know about all of the health problems related to CF. I always used what was called a "504" in my school district, which meant that I could not be failed out of school because of sick abscences. Also, I think it is important to let your child's teachers know about coughing fits, sometimes frequent bathroom trips, etc. It is not legal for your school district to fail your child because of abscences due to illness! I had a very hard time because while I was very sick I never looked very sick. Just find the right people in the school, the dean of students, the principal, and each teacher that will have contact with your child, and work a system out before classes start. Hope this helps.
