Laura, I am in the same situation you are! Having kids at the "invite over" age. It is hard to know who to tell and under what circumstances. It is a pain at times only because sometimes I JUST don't want to share this with EVERYONE! I am still stepping on my own feet cuz I am new at this too....Right now when I have told someone I tell them  she has this adrenal deficiency and is she gets a fever, is hurt (I give examples, broken bones, car accidents, etc) or vomits she needs extra cortisol because her adrenal gland just can't make enough to get her over the hump. I leave it at that......I tell them I am always avail. by my cell.....How about you??
