OP you can say the consultant recommended it or you can just keep quiet and not bring it up again. If she’s aware you get anxiety you could probably shut down any questioning by saying you have decided not to think about it anymore and don’t want to discuss it as it makes you very anxious. If it were me I have to admit I’d end up being quite rude and telling her to mind her own bloody business or at the very least make a dig about how she’s not going to support me making my own decisions so I refuse to discuss it...
Always a nice snarky comment is to say something about how medicine has moved on in modern times and the procedure is much safer these days...also is she aware of how different an emergency c section is to a planned one?
I am not saying this to scare you, but if you end up panicking during the birth, surely that could result in more danger to you and the baby, or in an emergency section...you could point out to DM that with that in mind, you really have to put your baby’s safety first - she won’t want you blaming her for making the wrong decision I think.
All that said ... I hear that birth can be a calm and relaxed experience if you make sure you are comfortable with the set up and birth plan. Despite my upcoming ELCS, I did consider a VBAC. Strangely I felt that if I could go the complete opposite way and have a Home birth, it would all be okay. Much more calm and peaceful pushing in my own living room, tv on in the background....for me, we live very far from the nearest hospital though, so I didn’t want to chance it, but it could be an option for you. I read that you actually have 2-3 midwives with you the whole time if you are at home, whereas in hospital they kind of pop in and out. You’d probably be more relaxed in a setting you can control.
Don’t get me wrong, I’m all for the ELCS but just so you know I’m not too biased!
