Angela,
I am where you are at...my 3 month old grand baby was diagnosed with CF via a sweat test. She is on enzymes, percussions, breathing treatments, and Zantac. She is doing well, but she has her ups and downs. Most of her problems right now are the mucus. More often then not she is throwing up, but that is a good thing as she is getting it out of her system.
Hang in there and know that there are some wonderful people on this site <img src="i/expressions/face-icon-small-smile.gif" border="0"> They have helped me out a lot. You and all of yours are in my thoughts and prayers! Hugs to all.
