the only thing she isn't trained in is surgery
The thing is that surgery (c-section) is typically the resolution for most labor and delivery emergencies.
Your hospital sounds like they will be very accomodating as far as giving you the birth experience that you desire, plus you get the added security of knowing that if anything (god forbid) did go wrong, a fully qualified staff would be able to quickly act in order to save you or the baby (as they did with your DS when his heartrate dropped suddenly).Of course you can always opt out of procedures such as having your membranes ruptured or being induced with pitocin, which would allow you to experience a totally natural labor and delivery.
The hospital that I stayed in recently when I had my daughter had birthing suites. For a little more money, they provided a huge room with a kitchen (fully stocked with snacks and drinks), spa bathroom and a couch that pulled out into a bed so that families could all stay together during the birth. Might be an option to consider so that your son can be there.
Obviously, the ultimate goal is a healthy baby and mom. My vote is to go natural, but in a hospital enviornment.
**ETA** I wanted to add (and this may be silly) that another perk (for me anyway) of delivering in a hospital is being able to have some down time after the baby is born. You have hot meals brought to you 3 times a day while you lay in bed. Someone tending to your every want and need. And the ability to send your baby to the nursery to be cared for when you get tired or just want a full night of sleep while recovering.
**Good luck on your VBAC. I had a VBAC with my 2nd son and it was an absolutely amazing experience**
