I have a 5 yr old who seems to be on antibiotics alot. I know thats normal for CF but i really cant tell whether she just has a cold or an infection. When she blows her nose and its yellow does that mean infection? I call the CF clinic and they prescribe Augmantin every time, then the "cold" comes back after being off the antibiotic for a few weeks. She did culture staph and h influenzae, could it just keep coming back? Help...... i feel like im always bugging the doctor!!!!!! Thanks!
