Hmmm... I don't think you have been told the whole truth about v/b after severe tearing. Maybe do another post about other womens experiences after such a birth?

Anyway, there are things you can do to help you get your head around a c/s.
1. Do not schedule the surgery, go into labour on your own before the c/s
2. Ask for the screen to be lower so you can see baby being born, make sure there are mirrors so you can see properly.
3. Make sure it states in your birth plan that if baby is born with no problems you want baby handed immediately to you after the birth with a warm blanket over bub.
4. Breast feed asap, make sure baby stays with you at all times if there is no medical reason to take him/her.

Best of luck and I hope you have a great birth
