if you have that tradition behind you and you grow up reading Greer and Friedan as most clever girls will do
I think it's harder for clever girls to get their hands on feminist literature, feminist thought, or get themselves under feminist influences, than it was In My Day.
I think there's a lot more 'cultural' sexism now than there was in the 80s, Xenia. This is slight thread-drift but when I read Greer in the mid 90s (my early teens) I was a bit of an oddball at school, but I wasn't actually pilloried. Now I have very bright female undergraduates in my Ivy League classes saying "I'm not some kind of feminist or something!" in horror when we discuss Homer. As if a feminist was a terrible, terrible thing to be. By contrast, in my first university classes (1999) I was far from the only student (male or female) saying "let's look at this from a feminist perspective". That's all but gone now (hah, not in my classes, where it's a big part of my requirement!) in their cultural terms. And these are the academic elite in liberal NYC.
Returning to the point of the thread somewhat, when you're both earning good money in your new flat, taking turns to make dinner, enjoying being a young couple, you don't tend to assume that things will change for the worse (and sexist-er) when you have a baby. But they do, they seem to, and one of the parts of it I'm afraid is that when a woman is on Maternity Leave she takes a huuuge paycut, and suddenly somehow it seems like the man makes the money and so gets to, eg, make decisions about large purchases or whatever. I've seen that happen a lot. I agree that "I am breastfeeding. You do all nappies, walk the dog, do all housework and incidentally please look after our other children" is a fine way to establish fair household roles (worked for me :) ) but it doesn't work if the man is out at work all day. Suddenly you are breastfeeding, the dog needs walking, house needs cleaning, food needs preparing, other children need entertaining, and before you know it you're a miserable drudge, or, perhaps woman who hasn't intended to become a housewife, but has become one by being there when things need doing.
My H changed all the nappies he was home for, that was the 'I'll do input and you do output' deal we made when the baby was born. Would I have left our son in a wet/shitty nappy when his father was out 'because it's his job?' no - that's shocking. But that's also how women end up doing all the childcare. Because it needs doing, and because women are there when it needs doing.
I didn't want to go back to work when my son was 6 weeks old (had no choice) - and I wouldn't recommend it as a fun option. But I am fairly sure it is one of the reasons I have an extremely equal division of household labour.
