This article is great.

My 2nd son was born by elective c/s at 37+5 weeks. My gut told me it was too early but my OB told me babies are all cooked by 37 weeks. My son's lungs weren't developed even at that gestation and he developed a premature lung disease and ended up in the SCU on oxygen, tube fed etc.. for 10 days. It was horrible.

So when it was time for my third c/s the same OB apologised to me for recommending the c/s when it was too early and said that he now did c/s at 39 weeks....I ended up going into labour the day before my elective c/s and had a perfect, healthy baby boy who knew he was ready!
