Watching with interest, DD is 2 and I'm due with DS next month.
I correct my BIL when he tells his kids not to cry/run like a girl and my dad a when he suggests things aren't suitable for a young lady (he's not actually sexist and has raised two feminists so I'm not sure where this comes from!).
I'm trying to surround DD with positive female role models, when shes a bit bigger I want to watch videos of people like Jessica Ennis-Hill and read her books with strong females. She likes gymnastics at the minute, so I show her videos of men and female performances as I don't want her thinking of it as a girly thing.
I've bought her a chemistry set (that will probably sit in a cupboard for a few years as she's a bit young!) and will subscribe her to the national geographical kids magazine when she's older as I think girls can be put off sciences and I want to try and counter that at home.
I like the quote by Mindy Kaling when asked where she gets her confidence from "My parents raised mewith the entitlement of a tall, blond, white man." I don't want DD to ever think she deserves less than DS, or DS to think he deserves more because of his sex. They will get the same pocket money and do the same chores.
Slightly rambling, but these are my thoughts at the minute, hopefully they'll get more coherent as the DCs get older!
