http://www.babycenter.com/growthchart/?CP_bid= This one is for babies...but I don't think it is going to be accurate for CAH if you do not have GOOD management of the hormones and cortisol levels. It is important that you get a "good" doctor that will monitor the growth, 170HP, plasma renin, etc. Once or twice a year checkups are not enough for a growing child. www.babycenter.com
