I want to start this by telling anyone that wants to try this to please consult with your doctor and make sure you both agree that this will be safe for you and the baby.

Now, yes it is possible. It is safest if you have had only one c-section delivery and there is only one scar that is low and goes from side to side.  To be on the safe side you may want to tell the hospital to have things ready in case you will need to go in for a quick c-section.

This really depends on the reasons you had the first c-section, so I can't stress enough how important it is to talk about this with your doctor.  Just know that yes, it is possible!
