Hi op, I had an elcs 5 months ago. I had gd and I was concerned about how big baby would get as I was a massive baby and my mum had a traumatic birth with me. You are right in what you are saying, traumatic birth experiences can increase your liklihood of having ppd ppa and finding attachment a bit harder. I would suggest having a debrief with a midwife around your first birth if you haven't already.
I met with the birth preferences consultant although I was late in deciding so I was already booked in by then. I just listed my reasons, they explained the risks around a section so I was fully informed , id already researched this all so nothing was a surprise and then they booked me in. They will probe a little to make sure you're making an informed choice and so they understand your reasoning but they'll ultimately go with your preference.
My elcs was great. Very smooth and I'd be much less nervous if we're lucky enough to do it again.
My tips are, bring slippers and a dressing gown for the surgery because you'll just be in a backless gown with no pants on!
Bring a phone with a calming playlist in with you for the start and end when your birth partner won't be with you so you've something else to focus on.
Arch as much as you can for the spinal and stay still as you can. It's not as bad as it sounds as they numb you before doing it but if they get the wrong place it feels like a wee electric shock in the spine which would have made me jump if I wasn't ready for it.
Air your wound as much as possible when your dressing comes off and keep it really dry, just rinse with warm water in the shower and dry with a cotton pad or kitchen roll.
High waisted everything and a pillow for between your tummy and the seatbelt coming home.
Take it easier than you think you need to when you're home. I felt good by week 3 then pulled my stitches trying to put my pram up by myself.
Make a section birth plan but don't be surprised if you'll only hear that morning what will/ won't be allowed at the surgeons preference.
