My son, has been very sick lately coughing and weezing etc. We have had him on the breathing treatment to no avail. The Dr. is sending him to a lung specialist. My mom told me I had a cousin die of CF and that she wanted me to look it up. My son doesn't eat very well, underweight, now he has dark circles under his eyes. After looking it up, he has always had bowl movement problems, he has moments where he's fine but of my three children he has diareaha alot. He complains of being very tired lately, NOT SO when you have a child who is manic ADHD. He comes home from school and just lays on the couch. Anyway I had some questions. Did any of the parents of children with CF notice that your child drewled alot, or just seemed to have lots of saliva? He is small for his age, and has been behind all the other kids with mostly everything. I am just wanting some more advice, and from people who have been there. Thank you!
