Is it coughing or asthma?

This post is part of a series that focuses on children's and women's health, as part of a sponsored partnership with Aurora Health Care. I'll never forget one summer evening at Chill on the Hill about two years ago. My family and I were enjoying the live bands and laid-back atmosphere of our favorite summer concert series in Bay View's Humboldt Park.

My son, four years old at the time, was running around non-stop with his friends near the stage.

All at once, I noticed that his face was red. Very red. It was a hot night, and everyone was sweaty. But when I looked at all of his friends, not one of them looked as red in the face as he did.
