When was the last time your daughter had a check up with her CF clinic? Have you mentioned it to her docs? The reason I am asking is because my daughter did the same thing. Not to alarm you but here is our story. She was diagnosed at age 3, always healthy. No pulmonary infections, not even so much as a bronchitis. Her diagnosis was a "freak" one. The doctor had her tested twice because he didn't believe the first one. Anyhow... that is background. She was seen in CF clinic every 4 months, no hospitalizations. Flash forward 5 and a half years. We noticed she was napping alot. Unusual for a third grader. Her clinic appts. were still every four months. All was fine at her last appt., on her next appt. she had lost alot of weight. We didn't see it they say because it was so gradual. Turned out her lung functions had gone down from a "normal" childs level to I can't remember what. Enough for them to admit her for 10 days. She bounced back just fine, it was another four years before she was hospitalized again. But I tell you what, I notice how much my girls sleep now, and start monitoring when they start sleeping more. My girls are teenagers now, they all sleep alot anyway but I watch to see if its for a long period of time, like days. I have a scale in my kitchen where they check their weight once a week. I wouldn't say I'm a fanatic about it, I just make a mental note. As teens they are responsible for keeping track of their weight. Not on paper or anything but a mental note so when they go into clinic they can compare what they are at home to what they are in clinic. We have a digital scale that goes from kilos to pounds. My advice is, if she hasn't been seen recently, mention to her docs that she is sleeping alot more. And if there is no real reason, like lots of physical activity, you know days at the zoo, swimming, stuff like that that makes a kid tired. If it's happening every day. Tell them that. What are her o2sats? My daughter had dipped into the 80's. We didn't know until her clinic visit. But in my opinion she needs to see her CF docs. Let us know how she is doing. Liza
