How is a RCS scheduled?

UberBiz

I had an emergency c-section with my daughter, and would ultimately like to do a VBAC, but FI doesn't want to hear about it and thinks it's too risky.

So, I'm sure I'll talk at length with my doctor about this, but how exactly do they decide when to schedule a c-section? Like, after the due date, early enough so you don't go into labor on your own, how do you know if it's too early or not? I'd really like to go into labor naturally and then have the c-section, do they do that? I don't really want it to be scheduled before baby is ready to come, if that makes sense... and if they schedule it later, and I wind up going into labor before that set date, then it doesn't really matter if it's pre-scheduled or not..
