Which is better? planned c-section or vbac?

Depends on you: A vbac carries the risk of uterine rupture, which is very serious. Many people, however, do have successful vbacs. Some hospitals or doctors do not have the insurance to do vbacs, so check with them. If you have had a successful vaginal delivery, the chances of vbac success are great. You will need to talk to your doc about all of the risks and benefits of attempted vbac in your own situation.
