> Mother = Birthing parent! Breast feeding = Chest feeding!
I don't expect midwives to start calling mothers "birthing parents", but perhaps midwives have been unsure what to call a woman who has transitioned to a person with a beard and had their boobs removed/flattened but their reproductive organs and feeding apparatus preserved so they can have children and naturally feed them. "Birthing parent" and "chestfeeding" works then, but not really needed for a woman that hasn't had all of that done.
