There is something called "opportunity cost". Small kids demand more, than just physical inconvenience during pregnancy. And small kids usually require their mother. (I cannot breast feed for example and mother milk is still quite superior to the industrial milk, but it is about more than that)

So all of it is time and energy, that could not be invested into a political career.

Have a baby and be out of the game for some time and you will have to struggle to catch up to those, who did not have a baby.

So I find it not surprising, that we do not have 50/50 for leadership positions, as they usually require intense effort, before reaching that. (networking, building skills, reputation ...)

So should we find ways, to support women more, to not "just be mothers", but also going other ways? Absolutely. But maybe we can start with not degrading women who are "just mothers" - as being a good mum, can be a 24h job. So I think the idea that women should be mothers AND have successful careers (and preferable both at once), just creates uncecessary pressure and stress. And the 50/50 idea creates that, in my opinion.
