My 6  year old CAH daughter is very assertive and can be emotionally difficult.  But I have heard people attribute those same qualities to me,  so it is hard to know whether it is CAH related or not.  I will say she is the ringleader of all my kids.  She is a very take charge kind of girl.  In school, I have not heard any complaints about misbehaviour-but at home, it can be difficult because she is so outspoken and stubborn.  And a tad bit mouthy lately, although my oldest CAH child went through the same thing at this age, and he eventually eased out of that.  It is interesting to read all the similarities posted by other parents.
