My 12 year old SWCAH daughter has ALWAYS been stong-willed, agressive, athlethic, demanding, independent ... a truely woonderfully challenging child.  Now add on the "normal" female middle-school Attitude and it’s contanst verbal volleyball in our house.  She is far more aggressive than either of her younger brothers, one who is also SWCAH, and one a carrier.  I believe it is both the gene pool and CAH that makes her this way.
