Jokes aside, there have been cultures where women went into labor and would deliver by themselves away from the tribe. It's been a while since I read about it, but iirc if she returned without the newborn is was either unacknowledged or at minimum just accepted as her decision. Imagine having a still birth or a child with extreme physical deficiencies prior to modern medicine. I do remember thinking when I read it that it surely resulted in women not returning, too, because childbirth can be risky even with a team of professionals.
Also wet nurses have been a thing, and the practices with that range from understandable to horrific - think wives of slave owners not wanting to breast feed, so they force a slave that's given birth recently take on the duty, usually as a priority over their own child. Course, there's always been women who couldn't produce milk, so it has been done altruistically, too
The only reference I have to go on off the top of my head there is Django Unchained where a difference was noted for those working in the house vs fields. I imagine it was used as emotional manipulation to bribe them with better living conditions in some cases, though
