This is why I'm so ambivalent about calling myself a feminist, in spite of having had an ultra-feminist as a mother.
It was my decision to be a SAHM. I did not want to go back to work after the birth of my daughter, my second child. I had been a single part-time working mother for my first child and I did not enjoy the working (outside the home) part of it. I felt I had missed out.
Staying at home for my second child of course meant huge financial losses on the face of it, as an employee. See, my husband and I both had exactly the same qualification, and had exactly the same employer to begin with. When I chose to stay home, he rose up and up and up, with pay increases and status, and I stayed down.
I didn't go back to that job, due to a variety of circumstances, till I was 60, and then only part time . But even if I had gone back full time, to the same employer, his salary would have almost tripled mine by that time.
Then he died, and I was a widow, and a pensioner. That was three years ago.
Looking back, I would not have changed a thing. It was my choice to be a SAHM and I much prefer looking after a small kid than sitting at a desk dealing with difficult clients, which would have been the other option.
My great, huge, luck when I see the comments here is that my husband was German and we were in the German system. Which meant the taxation system took into account my stay-at-home status, and so did the pension system.
Now, as a widowed pensioner, I am financially better off than I've ever been in my whole life, whether single or married, and that's not even counting the money I get from self-employment.
It can be done, IF the system is accommodating and supports your choice, whatever it is, including the choice to stay at home for childcare. I do realise that for the women here it's much more difficult. But:
I wonder: if staying at home to look after one's own children did not have financial penalties, would more of us (women) choose to do it? Would we still think of it as the lesser choice?
Because that was my main problem as a SAHM -- ex-female-colleagues who insisted I my mind would go rusty at home, and that what I was doing was not as objectively worthy as what my husband was doing.
