Here's an article in Time Magazine about VBACs (vaginal birth after cesarean) and the difficulties faced by some women in accessing this option when they give birth. An excerpt from the article:

Much ado has been made recently of women who choose to have cesareans, but little attention has been paid to the vast number of moms who are forced to have them. More than 9 out of 10 births following a C-section are now surgical deliveries, proving that "once a cesarean, always a cesarean"--an axiom thought to be outmoded in the 1990s--is alive and kicking. Indeed, the International Cesarean Awareness Network (ICAN), a grass-roots group, recently called 2,850 hospitals that have labor and delivery wards and found that 28% of them don't allow VBACs, up from 10% in its previous survey, in 2004. ICAN's latest findings note that another 21% of hospitals have what it calls "de facto bans," i.e., the hospitals have no official policies against VBAC, but no obstetricians will perform them.

Happily, in our area, Mercy Iowa City and the University of Iowa Hospitals and Clinics both support VBACs.
