I think we just need to separate the two issues.
It's absolutely undeniable that some interventions carry additional risks and therefore are best avoided unless the medical need for it outweighs that risk.
For example, my second baby was so small and prem, that the consultant advised Csection was the safer option than vb for that pregnancy - even though overall, statistically Csection is less safe.
My first birth had the potential to be totally straightforward and non medicalised - baby within average weight range, went to full term but not overdue, I had no complicating medical factors. Therefore, a CSection would have posed a greater risk than vb for that pregnancy. In fact, I did my research, and decided I would go for midwife led, natural birth if possible - which was what I had. DC3 was a VBAC - again, I took advice, and acted on it. The advice was: for this pregnancy, VBAC was safer on balance than csection, induction was to be avoided at all costs due to the scar, and best to avoid epidural as the midwife relies very much on the mother feeling each contraction with a VBAC. I would have liked to deliver at the MLU, but was told I was too high risk, so it was a hospital birth that time round.
So, three very different births, which reflected the needs of each baby.
The second issue, is where the mother has strong feelings about her needs, and whether these are best met in hospital/at home/with a lot of pain relief/ no pain relief etc. Again, different people will have different feelings. I don't feel comfortable with hospitals unless I medically need to be in one. Other people would only feel comfortable in hospital. I have quoted the example previously of my two work colleagues - both pg - who already have totally different ideas of what they want from birth - one wants to be in hospital and wants as many drugs as possible (her words!) while the other is aiming for a home birth.
My advice to any expectant mum would be to arm yourself with the FACTS - not hearsay- weigh them up, factor in your own personal perspective, ie whether you feel better at home/hospital etc, and then use that knowledge to plan for the birth you hope to have, but bear in mind that while there are things you can do to increase your chances, there are no 100% guarantees.
