We had genetic counselling.  It was explained that our non-cah daughter was a carrier like us.  We were told that any child we had would have a 25% chance of being born with CAH.  They also explained the treatments to avoid virilization such as dex and I was told that if I ever suspect I am pregnant to go to the Doctor asap and then they could look at treatment.  I think the chances are high at 1 in 4. 

The appointment lasted about half an hour and we received that only when I requested genetic counselling.  Around when Ashley was six months of age.
