Ous sons’ say "Adrenal insufficiency.  Give hydrocortisone.  Call immediately" This was per the recommendation of our endo.  Everyone does it a bit different, but I think as long as they know there is adrenal insufficiency, I pray we’ll be okay.  At least they have all the medical info on file & can give it if needed.  We are lucky in that myself or my husband is always with the boys -we’ve only been away together a couple times -(for a couple hours), but we still wanted them to have the bracelets just incase.  I would hate to have a car accident, for an example, and us be unconscious & not be able to tell them the boys needed particular care.  Our first son has been wearing his since he was a year old & our 2nd son has had his since he was  1 month old -just personal preference.  Best wishes!
