I'm another one who is really losing patience with this.
If you want to be referred to by your preferred pronoun, that's fine, and I'm sure the midwife would have been more than happy to accommodate.
Wanting the literature to change, because of a vanishingly small number of transpeople who give birth alongside the huge number of women who give birth every year?
I'm assuming he would pay for the change to be made and all the new leaflets to be printed, yes?
It just smacks of trying to erase women from everything. To be trying to erase them from pregnancy and birth is horrendous. I have never understood how you can 'feel' one gender or the other, as I have never felt "Oh yes, I am a woman now" - except for after giving birth. It is the one time I have felt strong and empowered as a woman, rather than as a human being.
If you have the bits to make and carry a baby, you are biologically a woman, and that is what the leaflets are referring to.
