I have a wonderful ds who's a teenager and a wonderful dd who's 7.
She is naturally forthright and assertive but I have tried to encourage her to be her own person and to have a sense of herself, not to just follow others but to find her own way.
This has been in subtle ways, when she asks for example about a situation or a choice or a blow up with a friend.
What I've tried to do despite the fact that we think she is beautiful, is to give her messages that her looks are not more important than anything else. So this means her seeing that I don't think it's more important than anything else re my own appearance. If she sees me being strong and my own person, then she will think that's normal.
I never gave her Barbies, and of course she's played with them else where but she didn't receive them (and their messages) from me, I think that is very important myself.
I think we have also tried to give her a real sense of choice sometimes, a sense of agency. So that when she was young I tried to not train her to be a pleaser but I used to say 'why don't you decide' about a painting etc or a drawing so that she could start to strengthen her sense of self which is grown through a million moments of influence and action.

I think it's also important to cherish and value who she is herself, intrinsically. I think girls can sometimes carry the whole weight of her mother's unmet expectations, a sort of 'mini-me revenge on the world' exercise. So many 'my darling princess' videos on FB. Look at any group of high achieving girls at drama club/music club/ballet class/swimming class, the will to succeed is often etched on the watching mother. I don't blame anyone, and I think I do it too in my own way. But the luckiest daughter is probably the one with the fulfilled and happy mother who knows who she is herself and is strong, supported and loving enough to create a world where a girl can grow up to be herself, not just an object for another's eyes and sexual satisfaction, or to be a compulsive pleaser. It's hard to achieve if you're bred to please first.
TED talks have a lot of speakers on how women see the world. It's worth watching some of the scientists who talk about how quickly girls appear to lose their scientific confidence.
Also another factor is that my dd has a very loving and kind big brother who plays with her and talks with her a lot. I think that has a very positive effect on her confidence with boys as I am already seeing how assertive she can be. She may expect to be treated as a person by boys in the future partly because of this.
Her dad loves and values her but her view of herself is likely to be hugely influenced by how my dh treats me. I think we are ok in that department, not perfect but ok.
I think having a child is a great act of faith in the future and it's a shame it seems to make us more selfish sometimes than more generous towards the world.
