I forgot who said this a few pages back
That was me.
Women have always done paid work, there have always been women who have worked outside the home, they just tended to be invisible. What the WLM advocated for was women to be allowed to remain in the kinds of jobs that, even in my lifetime, a woman would be expected to give up when she had children, if not when she married.
I get that some women are defined by their career, but the vast majority of women aren't employed in jobs that could be called a career, they just have jobs. Because those jobs tend to be less well paid than their husband or partner's job or trade, and because childcare in this country is relatively expensive, they have little choice but to give up work for at least the primary years or to have to take on a second job in order to keep the family afloat (very often women where I live take on a part time job around their partner's hours to keep the family afloat anyway).
The OP is very lucky in that she is able to make this choice out of a selection of options and will probably be able to keep up with her previous career and be able to return to it. The vast majority of women don't have those choices, and this is where I can't agree with "feminism being all about choice". Choice sounds fabulous, until you recognise that most women don't have actual choices between an array of equal options, what they have is a Hobson's choice between the potential that they might be made supervisor one day, but might not be able to eat properly until then because of childcare costs, or staying at home with any children they have. If we say that feminism is about choice, what are we saying to those women?
While we live under Patriarchy, I think we just have to trust that women are doing the best they can with their own circumstances while encouraging them to think critically about those choices and where they come from and working to expand the range of options they have to choose from. Even the women who 'choose' to go back to work between 3-12 weeks and put themselves through expressing are making that choice because of circumstances or peer judgement or because they live in a regressive country that fails to provide women with adequate paid maternity leave.
I'm not 100% sure where this rant was meant to go, but the whole concept of choosey choice without understanding the background against which those choices are made seems a bit one dimensional to me.
