Hi Alan, I was diagnosed with cf when i was 3 years old ,and at that time , there wasnt much known about cf at all. I also was very small for my age, and only had slight digestive problems. I had a normal childhood in every way, and the illness didnt get in my way of anything. I had never done any type of chest percussion, only because the doctor said , since i didnt have lung problems , i wouldnt need it. ( i do it now though) The great thing about your son being diagnosed now is that we have so much more information and better treatments, with more on the way. Encourage your son to stay as active as you can get him to be. Exercise is the best thing for the lungs, as well as the the rest of the body. Try not to "baby" him too much because he has an illness. He will need to be independant and learn to take care of himself. Cf can be scary at times, especially when things start to progress. Try to do everthing the doctor tells you in the way of treatments . The key to longevity with cf is prevention . When a probem arises, face it head on and aggressively. Find out as much info about cf as you can, and learn to ignore the statistical life expectancy. Too many perfectly healthy people die young for various reasons, for us to worry about the statistics of life expectancy for one with cf. My parents were told many diferent ages i wouldnt live to see, i've seen them all , and i plan to see many more as well <img src="i/expressions/face-icon-small-smile.gif" border="0"> .
