As you've had a section, the medical professionals by and large would push you in the direction of an elective for your second child anyway - and the flip side of the wanker coin from people like your twatty mate scolding you for not 'trying' are the people who scolded me for 'risking my baby's life' by making my own risk assessment and trying for a VBAC. The fact of the matter is it is anyone passing judgments on an individual woman's birth choices in conversation is a monumental bellend and just plain rude so fuck them.
I was SO desperate for a 'natural birth' with my first baby, I went two weeks overdue waiting, eventually agreed to be induced, laboured agonisingly for days with contractions every three minutes almost from the off, and eventually ended up with an elective section as I was exhausted and my partner was close to a nervous breakdown from watching me struggle for so long and neither of us having any sleep (went to be induced Saturday morning, baby didn't appear until Tuesday night - bloody horrible and quite traumatic). For ages I blamed myself for 'giving in' to the section, and even for 'giving in' to the induction, as all the 'natural birth' advocates sucked their teeth at that and said that if I hadn't had an induction baby would have come 'naturally' in their own time.
Fr second baby I was a lot more relaxed about things but still wanted to try for a natural birth, so booked myself for a VBAC at home; I had to make the case for myself against some opposition, whilst avoiding building it up into a big deal in my mind, because I knew my MH couldn't take another 'failure'. What will be will be was very much my mantra. This time I went into labour naturally, and it turns out I apparently just have very rapid onset, very powerful, very painful contractions pretty much from the get go even 'naturally' (had blamed this on the induction previously, and was looking forward to experiencing gradually increasing 'waves' with baby 2 - no such luck!).
Meconium in waters nixed my homebirth, and not too long into labour baby's heart rate started struggling, and despite all my powerful frequent contracting I wasn't dilating much at all. As I was moving around so much, staff were struggling to monitor baby and wanted to give me an epidural to keep me still. I looked at the way things were going for me, considered the likelihood that the ordeal I was about to go through had any likelihood of 'healing' my previous experience or giving me a healthy, vaginally delivered baby, and decided to go for another elective. Baby arrived screaming and well (and massive like her sister, both over 9lbs!) and I was home within 24 hours).
Looking back, I'm glad I tried again for a natural birth, but I'm gladder still that I knew when to stop and saved myself a lot of pain and upset. Taking control of things for myself, even when it didn't give me the experience I had wanted, was far more healing of my previous rather traumatic experience and far more empowering than pursuing a natural birth could have been for me under the circumstances. And most important of all , my baby was well and safe.
