Hi,We adopted our beautiful boy from Russia 2 years ago. Since then he has repeated respiratory infections/pneumonia and chronic diarreha. He also has asthma. When he gets sick he has lots of "coughing fits" and gags and spits up a lot of mucus - especially at night or after eating. He has only gained about 1 pound in the last year. When he is not sick he is very happy and energetic. We recently moved and have gotten a new pediatrician and she had us schedule a sweat test. He goes on Wednesday.I read that people with CF can have a salty sweat on their skin. My little one has asked me to "quit tasting him", sometimes I get a slight salt taste and other times I don't taste it. I know I just need to wait until the test on Wednesday, but I was looking for some input. Is there anything else I should be "looking" for? I should probably just relax until the test but it's difficult.We also adopted his older brother (4yrs) and he has had a few respiratory infections but no digestive problems.Thanks
