Ah, the things you learn when you decide to write, especially for science fiction and fantasy. Oh sure, there's the physics, the strange way the world works, politics, the edge of science, historical references for the fair folk, how legends and mysticism work (and they can be very specific in a way to make steam-engine engineers seem like punters), all that stuff. Including this small fact learned at my writers group last night, that there are, in this world, lactation consultants. Forget the knitted boobies and other things with birthing and (how can I say this) actual life, Lactation Consultants. Like a business card title (of which I've collected many interesting titles, part of the day job) not just a job responsibility.
