My experience was similar in that my daughter was 3 when she was diagnosed.  She was somewhat virilized - not severely so. (She has never required corrective surgery.)  Her bone age was beyond 7 yrs when she was 3 and she was tall for her age, but they just looked at her as being tall for her age.  As far as the virilization, I was told there was a wide range of normal and she was probably one extreme - and I should not be such a nervous mom.  I found out later that this particular pediatrician had NEVER seen a case of CAH before.  Fortunately, she had never had a crisis.  Finally another doctor referred us to an endo who immediately suspected CAH, ran the tests, and started the meds.  My daughter developed precocious puberty about 1-1/2 yrs later and we treated that as well.  It was secondary to the CAH.  Today she is 14, is 5’2-1/2" tall, and has the bone age of a 14  yr old.  Despite the fact that she is "not a salt waster", she has  had a few crises in her life and I had to administer the Solu-Cortef and get her to  hospital.  She was hospitalized this summer for a day when she dehydrated.  The point I am making is this - she was not diagnosed any earlier than your child and she still attained a normal height and bone age.  Also,this is a serious disorder.   Many times people will tell you that if not a salt waster, they are not so likely to have a crisis, but my daughter has a few times and she  has come close many times.  It still depends on the individual child and their CAH.  I am so sorry that your child was not diagnosed earlier, but I don’t know if you have a law suit.  Just be glad that you have a diagnoses and get a good endocrinologist - and pediatrician!  Other than that, relax and enjoy your child - and life will be normal for the most part.
