The last couple of days my daughter has been coughing only at night (when laying down). I'm sure it is due to the change of the weather that has turned cold and rainy. My question is does anyone give a breathing treatment (tx) for drainage or just let them cough like crazy? I have given the tx's and CPT's but it does not seem to help since it's drainage and the still continues to cough after tx. Just didn't know if there are any suggestions for this. I have popped her up, laid her head over pillows (almost upside down), etc. Anyone from Louisville, KY who has this same problem living in the Ohio Valley, if so, what is your tx and how well does it work for you? Daughter on Zyrtec, Singular (but does not seem to help like it should), Nasonex, and a saline spray at times to clean her out. I know she has CF but there should be some control over the sinus problems. What causes CF people to have so many sinuses infections??????? Thanks for your replys,Mother of 2 yr old w/CF
