A hospital has told staff to use terms like 'birthing parents' and 'human milk' rather than just referring to 'mothers' and 'breast milk' so transgender people are not offended.
Brighton and Sussex University Hospitals NHS Trust unveiled a blizzard of 'gender inclusive' phrases in a drive to stamp out 'mainstream transphobia'.
The Trust is the first in the country to formally implement such a radical overhaul for its maternity services department - which will now be known as 'perinatal services'.
Other changes include replacing the use of the word 'woman' with the phrase 'woman or person', and the term 'father' with 'parent', 'co-parent' or 'second biological parent', depending on the circumstances.
The new terms will be used for documents, protocols and Trust-wide communication.
They will also be used when discussing pregnancy, birth and parenting at a population level - such as at a meeting.
The Trust stressed that when interacting with a patient in a one-on-one scenario, midwives should continue referring to their gender.
A policy document released this week, said staff should not stop using the word 'woman' or other terms describing motherhood but they should consciously start adding in the word 'people' and other more inclusive language.
It said: 'Gender identity can be a source of oppression and health inequality. We are consciously using the words 'women' and 'people' together to make it clear that we are committed to working on addressing health inequalities for all those who use our services.
