I had a vaginal birth with my son who was born at 26.3 weeks. He was head down so I don't know if that was a consideration and I only had a 2 hour labor (after being in hospital 5 days with contractions). Maybe if they are already in the birth canal they would make it a vaginal birth but if there are complications you would have a c-section. Just my thoughts anyway. My little one is now doing well. Nearly 20 months and nearly walking!
