The normal ranges are for someone who does not have CAH. If we tried to keep our children at those levels they would be over suppressed. Normal for CAH is thought to be 300-1000 or even 500-1000. My daughter does much better in these ranges. She was oversuppressed for the first 1 1/2 years of her life. Now she is growing well and her cheeks are not so round and "moon face". Julia
