Hi, my name is Kathryn. I do not have cf but i have a question about it. I was doing my homework and one of the questions deals with cf. The question is as follows, Lauren is a 2 year old girl with CF. Because Lauren has this condition her mother frequently turns her over onto her back and cups her hand, and qucikly but firmly pats her sharply on the back between her shoulder blades. How could this help Laurens condition? Please reply.. or email me at bluekat@prodigy.net
