It's important to find a healthy balance between being too overprotective and educating your children.  As an adult with CAH who DOES lead a normal life, I can tell you that I've gone out drinking with friends, gotten sick, and handlied myself just fine.  Don't always assume the worst, and don't smother your children with worry - it will negatively affect them in the long run.  A normal life is very possible with CAH.
