Cystic Fibrosis - anyone any experience/knowledge?

[Mumsymum]

DD is 7 months old and has had an almost permanent couggh and cold since birth. She is also not gaining weight well although she is following the same percentile. I am now wondering about CF and wonder if she would have any other symptoms

my sister had cf, but I am sure her cough didnt start until she started having physio and treatment. Usual symptoms are : loose bowels - very smelly, projectile vomitting, slow weight gain and weight loss, small for age and repeated chest infections, salty tasting skin. I really wouldnt worry if she is only slowly gaining weight but if you are very concerned maybe have a chat with your GP about it?
