My son was just recently diagnosed with CF (3 and 1/2 years old). His problems are mainly intestinal at this point although we do a lot of the daily therapies to keep his lungs healthy. I was reading that the only thing that those with CF should NOT do was to go scuba diving. I have always wanted to take my son snow skiing when he was old enough - does that seem like a bad idea? Anyone with CF spend time snow skiing, and if so, any problems? Perhaps I should take him while he is really young (and lungs still in excellent shape) - or should I avoid it all together? Or maybe it's not an issue? I will be asking my doctor about this - just wanted some of your input!I didn't know if the altitude and cold air would be a problem.Thanks!Darlamother of Jared (3 with CF)
