We should also combat the meme that mothers are more essential than fathers. Babies benefit ("need" is a strong word here) from breastfeeding, but all other functions can be performed by fathers just as well. It's also important to note that mothers benefit from rest and support in the months following a delivery. So treating fatherhood as expendable is technically correct if you ignore a lot of practical realities, but we don't exactly treat mothers that use formula as expendable.

In the UK where I live and work, men get paternity leave and if I understand correctly it's meant to be as long as maternity leave, exactly so that there is no room for excuses about how women need to be away from work after having children whereas men don't.

Additionally, businesses get money from the state to pay the wages of their employers on maternity leave, and I think (hope) they do the same for fathers.

I believe other European countries also have similar arrangements in place.

This is true for commodity jobs. It would be nice to have employers realize that sometime there is a better-qualified woman -- like, one who would do better work -- and that maternity leave is a very short part of a long career.

Not actually true since scientists invented this magical thing thing called formula decades ago that is by all accounts almost as good as the real thing.
