I have a 2 and a half year old son who has never had a solid bowel movement. He has been on asthma puffers and had a few respitory infections and now my dr thinks he may have CF. He just doesn't seem to fit the profile. He is in the 95 percentile for weight and height and he doesn't taste salty. The only thing is that his bowels are always loose and he has respitory infections, although when he has tears that dry up they do leave a white streak on his face and you cn brush it off like powder. He does also have a protruding "pot belly". Does it sound like he may have cf? Thanks in advance for any input.
