Planned c-section vs. Vbac, which to do?

Depends. It depends on a number of factors which mode of delivery to choose after a previous c/section. First and foremost, the reason for the first c/section needs to be taken into account. Next, is the hospital equipped to allow for a safe VBAC. This is a question that needs to be discussed with your obstetrician. If you have your prenatal care in a "staff clinic", ask to talk to the attending physician.
