I go against the flow a bit here, but it's not straightforward.
My mum worked. Extremely high powered career in pharmaceuticals, ground breaking for women of her generation. I admire her hugely for her career successes and achievements. What she has done for malaria sufferers and AIDS patients deserves utmost respect and as an adult I can see that.
As a child I was pushed from pillar to post. Kept in boarding school and childcare (from 2 weeks). It affected me deeply. I felt she never had time for us and the time she did have was overshadowed with work commitments. She was away on business trips for weeks at a time.
However, I accept that this is the extreme. And by and large women with careers (or even men) these days wouldn't necessarily have to completely give their all.
And to an extent I think it affected my mum too. When I was 15 and my sis 17 I distinctly remember her coming in to the kitchen one day and saying "oh my two girls, what happened to your childhood". And my sis and I just looked at each other as if to say, well it was you who wasted it. With adulthood that feeling has mellowed. Mum also is ploughing so much energy in to her grandkids she's almost living our childhood through them.
The upshot is that I would never work to the extent that she did. I want to be there until my children are school age, and then maybe something part time.
But then I'm not a budding scientist destined to develop life-saving drugs so it's a pretty easy decision to make...
