Do most CAH kids lose height off of their predictions during puberty?  I keep asking my endo this and she’s kind of evasive.  It also seems like there is a new height chart. The endo has my son at the 75th percentile but his pediatrician put him at barely 50th.  The endo says his height prediction is 5’7" because his bone age is about 1 1/2 - 2 yrs advanced now.  But I think if we used the 50th percentile it would be lower.  And then if he loses a couple of inches during puberty...
