Joey, It is my understanding that the meds shouldn't have any ill effect to your daughter as you are giving her amounts that her body would normally make on it's own. Also, I noticed that my children(who do not have CAH) gain a few pounds before they have a growth spurt(vertically). If you think it may be caused by the meds, you should ask your endo about the dosage of the cortef. She could be getting too much.
