Thanks for the info. I don't know about dust mites, but her mattress and pillow are in waterproof/allergen cases, so that should help if that was an issue. She does have some old carpet in her room, that we could remove (didn't have the money to do the whole house at once.)
We've always had a dog, and both sets of grandparents have dogs, as well as nearly all my siblings and husbands siblings, hah, so she's exposed all the time. She doesn't seem to cough much during the night, but the evenings and mornings do seem worse than the daytime. She coughs at school and at home... currently she's had this cough for going on 3 months. In the past we've seen the same thing, where she gets a cold and the cough would linger for a few months. She never had any other symptoms that we noticed, so it was always dismissed by us and the ped. We have a new ped, and happened to go in this time because we were going to visit a newborn baby and wanted to make sure she wasn't contagious.
It's been hard to track when her breathing seems worse/better, because she's 1) attention seeking and 2) six years old. LoL If we start talking about coughing, she starts coughing, 100% of the time!
