Angelina good question, i once read that it is very difficult to produce milk for non-mothers
Basically are 2 hormones, prolactine, to produce it, and hoxytocines, to eject it.
Specially oxytocin is short life hormone, so, if you have prolactine but not oxytocin, your milk will accumulate into glands and it will end making an infection.
So, it is necessary going carefully.
Using hormones is always bad idea in a healthy girl.
So at the end, with risks for babies and risk for nurses, all the concept seems a bad idea.
