I have two girls. Ages 10 & 12. They were both diagnoses with CF 3 years ago. Their sypmtoms are fairly mild at this point and oral antibiotics have been able to get us back to 100% PFT's. My question is, at what point should they know that this is a degenerative disease. I don't want to scare them. I try to monitor what they read about Cf such as life span expectancies. I know they take me seriously when I say they need to wash their hands and don't share their water bottles but sometimes they just get lazy or can't refuse a friend who asks for a drink.They do know that kids have died from CF but we always say they have a mild form and so far it is. Their mutations are mixed. One is very common and moderately agressive, the other is extremely mild. It could go either way for them and it could be different for both. Currently one girls has displayed lung problems, the other has only had polyps and those have been completely gone since starting the ibuprophen treatment.Any suggestions about what young girls with CF heading into puberty are ready to deal with?thanks,Mom
