Effective communication in relation to pregnancy and birth is crucial to quality care. A recent focus in reproductive healthcare on “sexed language” reflects an ideology of unchangeable sex binary and fear of erasure, from both cisgender women and the profession of midwifery. In this paper, we highlight how privileging sexed language causes harm to all who birth—including pregnant trans, gender diverse, and non‐binary people—and is, therefore, unethical and incompatible with the principles of midwifery. We show how this argument, which conflates midwifery with essentialist thinking, is unstable, and perpetuates and misappropriates midwifery's marginalized status. We also explore how sex and gender essentialism can be understood as colonialist, heteropatriarchal, and universalist, and therefore, reinforcing of these harmful principles. Midwifery has both the opportunity and duty to uphold reproductive justice. Midwifery can be a leader in the decolonization of childbirth and in defending the rights of all childbearing people, the majority of whom are cisgender women. As the systemwide use of inclusive language is central to this commitment, we offer guidance in relation to how inclusive language in perinatal and midwifery services may be realized.
