Non-Maternal Writers Of 'The Maternal'

Yes, I know I haven't posted here in a long time- too busy writing up the tome!

Was wondering recently if anyone knows any people writing on maternity, and/ or lactation, that is NOT a mother or parent. Obviously I write about breast milk without ever having spawned, and I have a Northern friend who is childless and writing poetry about maternal sexuality, and another non-breeding mate here in WA looking and reproductive technologies and such for her MA... all of us dykes, or thereabouts. Sans infant, and in most cases not desiring one. Just curious.
