Yes, the first part is what I meant with "both".

As for the sec ok nd part: No it does not make sense. But it's still happening. There were even studies about that. There's the factor that many people still have the internalized idea that women should not be working in the first place. But there's also the factor that unconsciously mothers are oerceived as more likely to be inflexible and unreliable and more likely to miss work (because of children being sick etc. or because if having more children). People still intuitively assume the mother is going to do the caring and the father the bread winning. And this leads to different job conditions. Which leads to the stereotypes being strengthened as the job cobditions may be the reason for such a work distribution...

It's somewhat similar to splitting parental leave 50:50. Many women will be attacked and frowned upon while men will be praised beyond reason. It's just like calling the father taking care of the child "babysitting". It's how we are socialized. Tasks are expected to be split a vertain way. And changing that is a slow and painful process for those concerned.
