Children with asthma have difficulty breathing, and they may wheeze, cough, or wake up at night. Asthma symptoms can get worse when the child encounters certain triggers, such as dust, pollen, or smoke. Asthma is a serious condition, and it requires a doctor's care. An asthma attack can be frightening to both children and their parents. Guests: Anne Kelsey, MPH, Harold J. Farber, MD
