I am new to this site. My daughter is 18 months old and was diagnosed with CF when she was 2 weeks old. She recently had her first pulmonary function test. The results showed the possibility of mild blockages in her lungs. The doctor gave us 2 choices. First, do nothing and have her retested in 6 months or to start her on Pulmozyne. Not sure what to do. Is she too young to start on pulmozyne? If she has blockages I don't just want to sit and do nothing but just not sure if I should start her on pulmozyne or just wait it out and retest her to see if the PFT shows the same results. We do in next week to talk it out with the doctor and make our decision. Any advice would be appreciated!
