You must INSIST that your physician teach you how to give the injection. (or have someone else teach you) These children can crash so quickly and the ER staff --once they figure out what CAH is -- may not be able to reverse the effects of the crisis if the baby has gotten too sick. Find out for yourself how to do it. There is a website that takes you step-by-step and has pictures, also. I keep those instructions in the diaper bag in case someone else may have to give Connor his shot. Can anyone tell Marla this address?
