obstetricians and elected c-sections?

[ubiquitousslug]

Please forgive the ignorance of this post, but this is my first baby, so am not entirely up on the process and who you go to for what.

I now have a private ob who works out of St Mary's Hospital in London. if you go to an obstetrician is the assumption always that you want a vaginal birth? Do some obs only do vaginal births? If I want a caesarean, do I have to "pick" a surgeon? Or does the ob do that for me? Is the ob there during the surgery?

OBs is a surgical specialty so they should be able to perform a caearean if that is the method you choose.
I think the assumption is if you choose a OB you want more medicalized care then with a midwife. Midwifes are specialists in "normal" birthing. If you want low intervention as an aim then midwife is probably more likely to provide that. OBs can also provide "normal" birthing but are specialists in more complex/high risk birth and are also surgical specialists.

opps either can be an excellent choice depending on what you want.
