My 9 year old girl has had "use when you need" inhalers since she was 12 months old, following bad breathing episodes during colds. Last winter she received a preventer which we used during the winter then stopped. I was monitoring her peak flow readings until a year ago and she was generally around 130 at age 7. Now with a cold she is 120 at age 9. Is there something i can do with diet and exercise to help her. She sings but I'm noticing this is getting harder for her too. ( on a positive note she has been fine all summer and had no allergies).
