sarahi know exactly how you feel we are in South Africa our endo has only ever treated one other child for CAH and he is the most respected endo in South Africa
as far as hospitals go overhere thay have never heard of this condition wearing a medical braclet might help but as you say the hospitals dont stock the meds needed
perhaps setting up a emergency plan with the hospital is needed even if you buy the meds for them to use.
ask a endo to draft a emergancy procedure list we carry this with us all the time.
