It's really useful IMO when thinking about how people have thought about women and work in the past 60 years or more to consider that the fact that women can easily choose to have a few, or no, children is a very modern thing, and it's not some kind of ideological win, it's a technological change.
Yes, some women stuck at home in the post-war period struggled in many cases, especially if they were middle class women. Fewer children, the male workforce transitioned so much to an "employee" sort of model and better pay and working conditions for men along with that made it seem more appealing too. The work of running a home became far less as well, where previously it had not only been more time consuming but also required some significant expertise, and life in general was less communal. Although rarely you see a real consideration that being an employee has some real theoretical downsides, from an economic perspective, over working for yourself or your family, because it's hidden and not talked about much.
Working class and rich women have always worked or been able to, on the other hand, and the former have not necessarily felt that doing so represented freedom.
But the fact is that until relatively recently, not being consumed to a large degree with children and household work meant a woman could not marry and likely had to be a celibate. Which some did - there is a long tradition of celibate women dedicated to work more often done by men, and often doing it quite well and being highly respected for it. This wasn't open to everyone, class was sometimes a greater divide, some women (and men) had responsibilities to marry, and there are plenty of women and girls who aren't willing to be celibates and they found they had to make a choice.
It's now become so normative to have women working in the public sphere that many women find huge push-back if they express any interest in or desire to opt out of that. What's more society has rearranged itself around families with two parents working to such a degree that it's almost impossible for many families to make that choice. Housing prices don't allow for it, and in places where there is socialized childcare it's almost worse. There is a strong social sense that if you are a working class mother home with kids you are a bit of a slag, and if you are university educated you are wasting your education.
But - it we take seriously the idea that we are animals, that our reproductive role is a part of who we are and actually, our physicality and the way it works is a god thing, is it really feminist to have a society that so much wants to separate having children from things like career or your daily life? To monitize and institutionalize childcare on a mass scale, not only in nursery settings, but we now see due to the pandemic the degree to which schools are mainly arranged for childcare.
