My son has asthma.
Oh, he has a common inflammatory disease of the lungs?
Yes. He was diagnosed as a baby.
Oh poor baby. :( He must have a lot of reoccurring airflow obstructions and bronchospasms.
Yes and it mainly occurs after an illness. 
You must see your baby wheezing, coughing or shortness of breath sometimes.
Yes and it is really sad. It is so scary.
Oh no! Have you had any episodes this week? They say that symptoms can occur a few times a day or a few times a week.
