Iknow when I take my son to visit the endo he always asks what new things he has learnt in the last 3 months since I saw him(he's now 14 months) and so far 'touch wood' his progress in everyway has been advanced for his age. I also have heard alot of CAH children are quite often advanced for there age and for the opposite reason that you read- that there being too much testosterone when they're in the womb helps them not hampers them. i hope this helps you Lisa D
