Joey, I have found a page where it says that resistance to infection trauma and other stress is diminished because of reduced cortisol. And also reduced resistance to infection is stated for too much cortisol. She could possibly by a kid who is more susceptible to ear infections. Or you may need to look at her cortisol levels a little more closely. The website I used was from www.merck.com/pubs/mmanual/section19/chapter269/269f.htm
