Doctors used to think that if you had one baby by cesarean, all future babies must also be born that way. But doctors now know that 90 percent of women who delivered by cesarean are candidates for VBAC, or vaginal birth after caesarean. Depending on the reason for your prior cesarean, you may be able to deliver vaginally, especially if you have no major medical problems, the baby is healthy and in head-down position, of normal size, and any condition that necessitated your last cesarean isn’t present. If you have diabetes, high blood pressure, or are pregnant with multiples, you are not a candidate for VBAC.
