I just wanted to buy more time with my kids.
I'm one of a large group of siblings, with a SAHM (we were all born late 50s early/60s) - it was more usual then for women to automatically drop out of work on having the 1st child - in fact, in some jobs they were required to resign on marriage & children.
As a child growing up with a SAHM, I took a lot of things for granted, about my mother's availability. But you know what? I know that if my mother had had fewer children and worked in paid work outside the home, I"d actually have had more time with her.
My memories of my childhood are of a harried harassed parent, and an absent parent. We were not poor by any standards (we sailed, had boats & took ballet lessons, did Girl Guides etc etc) - all the aspects of an affluent middle class family life. But there was always a worry about money, and there was tension between my parents, and my mother's mental health was never very vibrant. She didn't have a mental illness, but her well-being wasn't great, when look back.
She was a brilliant home maker& household manager - we ate cooked from scratch meals every day, she baked weekly so we only ever had home made cake, biscuits & bread; she made all our clothes. We lived rurally so were ferried everywhere and had a wonderful childhood. Not with the kinds of materialistic possessions (we always had practical cheap cars, and no television or stereo systems & all of the modern stuff).
But my memories are also of an harassed busy mother who rarely had time just to hang out. And the tensions about money.
So, you know, OP don't valorise "time with your children" over everything else; don't use that as an excuse. Because your DC will pick up on the other things.
I also think my mother would have been happier and mentally healthier if she had had some relationships outside of the family, through paid work and the recognition and satisfaction that comes from that. She got rather lost after we all grew up & had to find a way to remake her life.
And paid work was really out of the question for her after 15 years out of the workforce. She had qualifications, but she just could not take the pressures even of job-seeking.
