I totally understand your concern. I'm sure you are in a difficult position. The six feet apart rule for kids with CF is really important. It's difficult to approach conversations like that with your daughter, I can imagine. My own mom as voiced some concerns to me before, after doing her own research into CF. One of the most helpful ways she has approached those conversations with me is by saying "I still have so much to learn, but I am concerned about this xyz. What has her doctor said about that?" Or she has mentioned that she has read articles here on this website about certain topics before and asked if I would read them too and let her know what I think about it. I dont know if any of that is helpful, but please know I totally understand your concern and I am hoping this helps in some way!
