I have a little girl with CF only 5 short years old. The activity is awesome for them, the Asthma attack is concerning. I would make sure that due to environmental asthma and allergies that she looks into creating an environment within her home that is completely toxin free. We have and know so many with asthma that this has helped and for those with asthma alone, many able to get off of inhalers and prescriptions. I have suggestions for you and her and you can contact me at email@example.com.
