What is it that makes a person a boy or a girl? From our cradles to our graves, a pair of letters, either XX or XY, will define much of our lives. "It's a girl!" or "It's a boy!" will be the first label applied to us, the first thing said about who we are as an individual. For every person in every society, gender has a fundamental affect on what we choose, how we live, and how we think about the world and how the world sees us. Sex is one of the most powerfully defining concepts that we have.
Of course, we assume that we know what this gender thing is: boys are boys, girls are girls. Sex is fixed, biologically determined, simple. But what if it isn't?
As Jane McCredie moves from laboratories to café tables, trying to find out exactly what sex is, the picture becomes much more complicated. Evolutionary psychologists, trans-gendered people, children playing with trucks and dolls, hormone specialists – they all have different stories to tell about what makes us girls and boys. These stories force us to stop and ask, 'is it really so straightforward?' Are we all really just stamped out in blue and pink? Leading us on a remarkable exploration of the ground where biology and culture meet, intertwine and ultimately blur, this book examines the new science which is helping us answer these important questions. Showing that we are far from "opposite" sexes, Making Girls and Boys will challenge everything you thought you knew about men and women.
Since the youngster is 5 yrs old she would have identified with her gender for about 2 years.
I have no financial or any other input into this publication BTW.

I'm also fascinated by two close colleagues who have had their first babies at about the same time, well 1 day difference. OK a scientific expt can't use a n=1 but. One is male one is female. OK they get dressed in little boy and little girl clothes but their nature to the world is totally different. Are we training 12 month olds to be boys and girls or is it totally natural. OK I and I think everyone else will say it's totally natural. So if a baby boy acts and responds as female, and a baby girl acts and responds as male; what do we do? And when do we do it? In hind site I can say I should have had SRS when I was born, OK I know I'm over the top, But when realistically do we make a call. I have a friend whose son wore and adored nail polish for years of his early life. He is definitely male. Do we seek council for boys who want to wear skirts and dresses, because their sisters do? Do we seek council for girls who want to pee standing up because her brothers do? This is a very difficult area. 'Normal' people ( I hate that as well, I am normal) never think about these issues. It's only later when you realise that you have been sexually mis-identified that these issues and ideas arise.
As many of you know, I think with my fingers. I'm happy to debate this topic. I'm particularly interested when people think when and why we should intervene in a childs' sexual versus gender outlook. Should we? If so what do we do?
