My 7 year old daughter has classical CAH but is non-salt wasting. And 10.5 years is perfectly normal for underarm hair growth, although I'm a nervous ninny and had my 9 year old daughter also checked for CAH. She doesn't have it, but is a carrier of the gene. You may want to get her screened just for the knowledge in the future. If she carries the gene and marries someone who carries the gene, they have a chance of having a CAH child.
