chandelina - "tend to be" is what I said - women have been shown to be better at getting on with it, and not having that "ooh, i don't know what to do" thing that men seem to have because the baby concept isn't alien to them, because they're more likely to have played with dolls as children.
same way that a child who has climbed trees will be more willing to get up a ladder as an adult, or walk along a high gang-plank, or (as I seem to do a lot) walk along the edge of the roof to check out the state of the tiles from the outside, without fear of falling.
same way that a child that has learned how to change a plug will be more likely to try to solve an electrical problem, such as changing a fuse in the fusebox, or change a socket plate.
same way that a child who has learned to cook will be more capable of cooking a meal for themselves when they leave home.
same way that a child who has played with lego will be more likely to be able to solve mathematical and geometric problems, because they've learned how to visualize and solve 3D puzzles.
It doesn't matter if you're a boy or a girl for any of these, i justmeant that in the past, it's traditionally been a girl's toy - which is why lots of men today don't know where to start when faced with a baby.
If boys play with dolls, then they will become much surer of where to start as adults.
