Not sure if Q would be used for cup sizes, given how bra sizes work. This picture has plenty on the milk-producing abilities of these gals, which... yeah, ok, but, as a worldbuilder, this is actually something I take into consideration with my own work. https://twitter.com/NegativeBloom_/status/1381337186809823241

For instance, all of the original sapient races in my story setting were mammalian before some of them were altered into things like Centaurs, Minotaurs, Harpies, and Merfolk during the Divine War, when the gods' fighting warped reality. Thus, I have to decide if those changes-

-also switched some of them from being mammals to non-mammals or if they only took on certain traits of non-mammalian creatures, like birds & reptiles, while retaining their mammalian attributes. For example, should my Harpies be egg-laying mammals or-

-should they have become more avian OR should they give birth to live young? What about my Frogfolk race? Do they birth live young & produce milk for their offspring or are they essentially humanoid amphibians, complete with being coldblooded?

Something as simple as whether a race is mammalian or not can actually have a big impact on how they work. After all, if the young are not sustained with milk, how are they sustain? Do the parents feed them the way birds feed their young or-

-are they born ready to eat most of the same things as adults? Given that ancient cultures would often celebrate when a child was weened b/c it meant he or she had greater odds of survival, there's a stage of development that a non-mammalian race would not have.

One thing that the image at the start of this thread gets wrong, in my view, is that it states the Minotaur women in this setting can produce milk at any time. That doesn't work for me b/c most mammals cannot get pregnant while they're nursing.

This is a mechanism which ensures that the female's body isn't having to divide its resources three ways - sustaining her, sustaining a child in the womb, & sustaining a child being nursed. Plus, if there's no child to feed, why produce milk?

That said, I could see Minotaurs being able to induce lactation a lot easier than other races can. It's something I've decided is true of my Orcs, which enables adoptive Orc mothers to swiftly fill in for a biological mother if the biological mother has died.

I know this is probably a bit of an odd thread, but the point I wanted to make is that worldbuilding can be about more than just geopolitics, magic systems, & technology. Sometimes, the most basic aspects of biology can do a lot to shape a fictional culture.

If your fictional race lays eggs, how do they care for them before they hatch? If they give birth to live young but are not mammalian, how do they feed their young? How do those things affect their ways of life & their cultures? How do they affect the lives of their children?

And how would those things affect their perspective of races who work differently? Do egg-laying races think live births are horrifying? Do non-mammalians think nursing young is disgusting or would it be something they'd envy b/c it means a little less hassle for the parents?

This are fun things to consider & there's a lot of interesting storytelling you can do with ideas like these. Don't be afraid to think about these issues b/c it may lead to some interesting scenarios that you wouldn't have had otherwise.

End of thread.
