Australia’s leading university has encouraged staff to use “parent-inclusive language”, such as “chestfeeding” instead of “breastfeeding” and “human milk” rather than “mother’s milk”.
Similarly, the terms “mother” and “father” should be replaced with “gestational” and “nongestational” parent, according to the Australian National University’s Gender-Inclusive Handbook.
