A c-section is a major surgery... I get VBACs can be risky but come on...
It will help if he comes to the appointment with this doctor and asks any questions he might have there. The doctor can hopefully ease his fears. He needs to educate himself because he clearly doesn't know a whole lot by the way he's talking.
By the way, more women die during c-sections than natural birth in the U.S.:
“About 36 women per 100,000 die while undergoing a Caesarean section, or C-section, compared with 9.2 deaths per 100,000 vaginal deliveries, according to a published study in the Journal of Obstetrics and Gynecology.”
This is also NOT including all of the women that die from complications resulting from their c-sections. Hell, Torri Spelling almost just died from complications even. That's not to say vaginal births are perfectly safe but yeah.
