Except, they don't do this.
What they seem to do, is list all the horrors of c-section (which is based on emergency c-section research), scaring the woman senseless, whilst keeping fairly mute on all the dangers and risks of vaginal birth.
It's simply incorrect to say that an elective c-section is much worse. At least in a c-section, the hospital date will be planned and they have to have a certain amount of people present. Contrast that with women giving natural birth who feel like they've been just left to it as the few midwives on the ground rush around between patients.
Then all the women pressured to have natural birth, only to a have a horrific one, which might end up in an emergency c-section anyway (which would be riskier). The women who'll end up with permanent faecal incontinence and painful vagina for years & years due to botched up stitching.
There are benefits to the baby from vaginal birth, but I'm not sure if the risks are worth it is the mother has concerns.
However, please do some reading up on breast milk @Padronpeppersplease I have asthma, eczema and allergies, and sometimes I wonder if my life would have been easier and better if I'd been breastfed, which I wasn't.
