Five-year old Aubrey Inman watches television during a treatment for cystic fibrosis while her sister, three-year old Adalyn, keeps her company. At least twice a day, Aubrey is required to take several medications, use a nebulizer and wear a vest that fills with air and pulses around the body to shake up the lungs to help break up the mucus.
