SherryTracey,
I would say that yes you should find a pediatric endo. They will want to monitor and treat your child in any event they might need to. Your pediatrition will need to confer with him/her also about the CAH. Other then that I am not sure who you will need to see. Your endo should be able to help you with that. Also have you considered consulting a Genetic Counselor? They can help you a lot with information also. I know they did when my husband and I (both carriers) found out we were pregnant with our second (non affected) CAH child. Good luck to you! :)
