The issue here is the language (or lack of it) and the fairly complicated context with women's reproductive rights being constantly under attack by people who see us as vessels, and the constant devaluation of pregnancy.labour , bf, childbirth, child rearing.
So all of this is probably an issue due to the patriarchal context of societies all over the world.
If our reproductive labour was not seen as a threat to men, or a service to be utilised, or a thing to be minimised, all of that sort of stuff, we would be able to describe and deal with these newish situations a lot more easily.
There is a drive to minimise what women are doing when they grow and birth babies and then hand them over, in most of the animal world removing a baby from its mother is recognised as being awful, unnatural, a no-no. Humans know this too. That giving birth to a baby and then handing it over is a pretty fuckign massive deal. In order to sanitise and deflect from this, words need to be found that obfuscate teh situation. Made me think of "friendly fire" and "collateral damage" then, also both from our USA friends.
