Good luck for your appointment op!
It's good you have a clear idea of what you would like, and your own personal reasons for this are exactly that - personal! You do not owe every nosy person an explanation, although good to have a frank chat with the obs team when you finally meet them. Important to let them know any particular worries you may have, so they can address these.
Ignore the pp 'concerned' for societal implications of women requesting c sections. While there is a time and place to discuss the complex reasons behind c section rates at a trust or national level, it is not relevant to your decisions right now.
Your concern is rightly for you and your baby, not the opinions of others. There are some highly judgemental people who will comment in a derogatory way about women having csections. It can be very upsetting to have this directed at you, especially when you are pregnant (although it still annoys me now, and I am a couple of years down the track from my first baby) These comments often come from a place of ignorance, or their own personal moral crusade. The main thing is you are fully informed what the process is, the complications (which will be discussed at length in appointments pre op); and you have a realistic expectation regarding recovery as well.
I have had 2 elective c sections, at different trusts. I do not have any regrets about choosing this pathway. Like you I had very clear reasons for this (I am a hospital consultant, and knew full well what I was signing up for, and the pros and cons)
My first was in London at a big teaching hospital. Midwife appointments were hit and miss, sadly there were some incredibly judgemental midwives who made it very clear they did not support elective c section, and I had to push for this. The change in demeanour in one midwife during an appointment when I told her what I wanted was startling. From friendly to openly hostile! I was treated in an incredibly patronising way by some midwives, which made for a really negative experience during what should be a lovely and exciting time. As per their protocol I had to meet with a senior midwife to discuss what was involved, and that I understood what I was consenting to, before they would agree to then refer me
to meet the obs consultant, who was happy to book me in. However this process didn't happen until very late in pregnancy, and the midwives made me feel unsure for much of the pregnancy whether they were going to allow it. I found this created a sense of uncertainty throughout the pregnancy, which in itself then causes anxiety. The surgery itself was fine (although aftercare appalling on the wards - a separate issue!)
My second was at our local district general hospital in the country (as we had moved). Absolutely fantastic experience, lovely midwives and staff, absolutely no problems at any stage, surgery went well. As it was a second c section, it seemed a complete non-issue when I requested one again, and the attitude of the midwives was positive and supportive rather than judgemental and dismissive as I found them to be in London.
So much of the experience seems dependent on the attitude of the team you happen to meet in clinics. All I can say is good luck op, be clear what you want, and and I wish you all the best!
