Her natural duties haha. New moms work everyday.
Would you rather somebody else take care of your kids or your wife take care of your kids?
Ask women that go to work if they would rather be at work away from their recently born baby or at home with their child to take care of their needs....and surprise, surprise..... you might get an answer that they'd prefer to take care of their child.
And that's despite all the feminism bullshit being pushed over the last several decades.
Yes, natural duties. It's called being a mother. Growing a child in your womb for 9 months and then caring for that child. Although I guess that's sexist in this current strange world.
Natural duties of a man? Providing for his wife and his offspring.
These ideas are novel in 2018? Weird.
