Well, I would say that part of this is going to really depend on your history and last birth. Or births.
Many women have no problems with VBAC's, but unfortunately, you don't really know how things will go until you are in labor. Perhaps "pro-intervention" means that if you get into trouble trying the VBAC, he will intervene so as not to risk you or the baby. That's not such a bad thing, in my opinion.
I work in a matenity ward. I have access to all the mom and baby patient charts. I see all the time that people have "birthing plans" and don't want this or that. They are very clear about their wishes for their birthing experience. But, sometimes, things don't go as planned and I think a good practioner of any kind makes a mom feel it's okay and not a failure of some kind if there has to be Plan B for the health of the mom and baby.
None of us know your medical history. There's no way to know if a VBAC is ill advised for you no matter how much you want to try it.
Before switching doctors, I would schedule a time to really, really talk to him about how you feel, why it's important for you to at least try, ask him concise questions about why he might not be all that on board with the idea and then go from there.
We have some of the greatest mid-wives at my hospital, I trust them with my own daughter who is due in May, but let me tell you, they don't hesitate to have a room prepped and call for back up if it becomes necessary.
You have the right to change doctors, you have the right to change your mind, you have the right to go where you want to go and feel comfortable.
Ultimately, it's your birthing experience.
If you really love your doc though and have a good history with him, I'd have some more communication with him first before switching.
As the mom of two kids with very differing birthing experiences, that's just my opinion.
I wish you the very best!
