Mary - I hope and pray that that might be the case with my son but we were told when he was 12 yrs/9 mos. that his bone age was 14-15 years. It sounds like your son’s bone age always matched his chronological age. My son also went through puberty very early. He was shaving at age 13 (even before my older son who does not have CAH. Whewn the doctor told you that your son had finished growing, had he gone through puberty?
