sorry, southside... hope i didn't offend you... like i said, it's just from personal experience.
just last saturday, i explained on three occasions to parents at my playgroup that we let the children play with what THEY want to play with NOT with what the parents want them to play with. i had TWO dads separately make disparaging remarks about their son playing with dolls/kitchens etc.
i read a study/saw a programme (can't remember which) that theorised that the measured differences in girls' abilities in maths/sciences is directly proportional to the toys that they are given to play with... not as many "building" toys (bricks/lego/blocks) as boys, so the girls' spacial awareness and the ability to visualise objects from all angles is not as well developed as it is in boys. that their poorer results have NOTHING to do with their abilities, rather with what they've experienced from childhood.
i HATE toys'r'us for that very reason! have you ever noticed the pink "prettiness" of the "girls'" section.... all dolls, clothes, make-up, VACUUM cleaners, kitchens etc....
while the "boys" section is robots, cars, dinosaurs, smash'em'ups and science toys??? completely DRIVES ME CRAZY!
ps> caps for emphasis, not intended as yelling... welll most of the time! LOL!
