When our DS was 3 (he's now 21) we flew from Michigan to Florida. We were supposed to have a flight where the nebulizer could be plugged in (this was in the days before portable nebs), but it wasn't. The flight was only an hour long, and he had a treatment right before we left. But in flight he was sure he was having an asthma attack (it was actually a panic attack). His breathing was actually fine, but during that trip, every time we sat down to eat, and he swallowed his first bite, he thought he was having an asthma attack. The nurses got to know us REAlly well.
He got sick EVERY time we went on vacation, up till age 15. When he got a viral infection, we had about a 3 hour window before it turned bacterial, and then he'd end up in the hospital with pneumonia. Our doctor finally agreed to send a z-pak along with us, so that we would have antibiotics, if needed, plus I brought the whole other arsenal of meds.
But we learned to take it easy, and to love what we could do, rather than fretting about what we couldn't do. Now that DS is 21 (and SMOKING!!!!!!!!


), I'd happily go back to the grade school days when we had more say on the care issues.
