I may be jaded but this is why I think an OB might suggest you need a caesarean...
Go to a make-up artist. She is not going to say you look beautiful naturally and don't need her services or to buy any products from her.
Go to a plastic surgeon and ask what you think needs doing. He is not going to say you're great in the body you were given and send you on your merry way.
Go to a shop and ask them which clothes they have that might suit you. They're not going to send you elsewhere to shop because nothing they stock WILL suit you.
Go to a dietician and they're not going to tell you your diet is perfect and that you've wasted your time coming.
Go to a chiropractor and they won't tell you your bones are 100% better off without them.
These people rely on pregnant women to earn a living. Some will, absolutely, tell you that they think you should birth naturally... but it's not exactly the most common thing to happen. They may not say, "Yep, need a caesarean," but they'll have various interventions in mind they might suggest "if needed."
They're trained to see the faults in pregnancy and birth and to "fix" those with their medical methods.
They're also about risks and risk management. It makes sense that a surgeon who is trained to "fix things," would feel better about managing those risks themsleves with a scalpel than just waiting to see what nature decides to do. That's fine - they can feel that way... but it's not their birth, so their anxiety over the course nature may take, IMO, means pretty much nothing compared to the anxiety a mother feels about her desire to let nature do what it has to do, and have her surgeon ONLY as a back-up if nature starts to screw her over, when that option is kind of stripped from her.
I couldn't care less if women want OBs. Or caesareans. Or every drug known to man during labour. That's all good for them and if they feel happy at the end of it, then I'm happy for them.
It's not what EVERYONE wants though, and it's certainly not what I want for myself or my baby, and my research has suggested that being in the care of an OB as a VBAC patient in a private hospital means odds are against me getting that VBAC, and instead, ending up with a repeat caesarean.
Apart from feeling homebirth is just as safe as a hospital birth, I figure that nobody in my home has an interest in cutting me open. There is no surgeon there thinking about how they could just "Get this over and done with without any potential problems arising," by putting a knife to my belly. It means that I feel safe and secure in hte knowledge that my midwife will have me transfered only if she truly thinks I need medical care. It means I can rest assured that my own best interests are coming first... not the best interests of the hospital, to clear me out of a bedroom, to meet "hospital policy," or because they're feeling anxious about the fact they're not in control, or worrying I might sue if they don't do something and something goes wrong. Litigation is probably a massive reason why some act as they do... if I was threatened with serious consequences all the time, I'd want complete control too... but obviously, my concerns are with ME and my baby not THEM.
Anyway, that's how I see it anyway.
