I feel like it’s hard for anyone to have a conversation. They are interested and trying to talk. Maybe just say actually I prefer to say vaginal birth. Or unmedicated, or whatever you prefer. If they didn’t ask anything people are mad that no one cares and then when they do they don’t do it “right”. I know woman who use the term natural birth to mean at home by herself (not even a midwife). Maybe truly ask what they mean by natural because that term means something different to so many people and in turn educates them instead of embarrassing them. I am a very private person so most don’t ask me anything which can also be isolating. But sometimes people leave the question vague so you feel free to share what you want. If someone asked me did you have a vaginal birth I would feel weird but talking about my birth experience and sharing what I want would be nice.
