Gum I'm aware of the risks of a c-section and while pregnancy itself weakens your pelvic floor, labor is what is responsible for most serious damage rather than pregnancy itself. Also, while a small baby can do damage, its much less likely unless there are specific issues with position, which my consultant and I will also be monitoring as the birth nears.
I'm doing, yoga, pilates, specific pelvic floor exercises and am in physiotherapy to manage my pelvic floor and back in light of my specific risks and issues. I've already developed PDP because of my back issues despite all of this extra work so its something I'm taking very seriously and am pretty informed about.
In a private birth situation, a mother can opt for a c-section simply if she wants one. If I told my OB today that's what I wanted, he would book it in now for my 39th week (I'm at St Thomas not the Portland by the way). Its my personal decision to wait for the growth scan at 32 weeks to see if I want to opt for a vaginal birth vs and elective c-section, not the OB's. I'd like to keep both options open for as long as possible before making a final decision.
If I opt for a vaginal birth and it isn't going well, we will all do what's best for the baby and me, but at no point will the consultant's totally irrelevant concerns regarding their or the hospital's c-section rate play any role in that decision making process. As long as it has not become specifically more dangerous to switch to a c-section, the option to do so will always remain available as the birth progresses.
Friendly every trust and every country for that matter is different. In Milan, they offer a c-sections to anyone who they think is having anything bigger than 8lbs! According to NICE guidelines, all women (NHS or private) should be able to choose what they feel is best once provided with appropriate information and medical advice. However, most (though not all) trusts completely ignore these guidelines.
I was on the NHS up until 20 weeks and was very happy. It was always my plan though to switch in later pregnancy though for the additional scans, monitoring and options that are available to me. My NHS care at St Thomas was faultless though and I miss my midwives, though the midwives in the private wing are equally lovely as is my consultant.
