Both of my children were diagnosed their first month and are doing well. Regarding your question about sinus surgery. Sinus problems often go along with cf. My nephew (also with cf) has always had sinus infections and has had two surgeries as a result. I knew about his problems so I have taken my children to see the ENT dr every few years for a check-up even though they have had zero problems with their sinuses (no runny noses, no infections, no complaints, nothing). At our last check-up in March, the dr said they should get cat scans of their sinuses to get a baseline for future reference. Well both cat scans showed complete blockage of their sinuses. So my son just got sinus surgery last month. He has done fine (except for he now has this cough from drainage we think). We are waiting to get my daughter's surgery.
You are doing a great job of educating yourself. Keep up the good work and enjoy your precious daughter.
Sharon, mom of Sophia, 6 and Jack, 4 both with cf
