Scheduled for a c section during my 39 weeks due to her still being breech.

I have a few questions that have my nerves worked more than the rest

Since it isn’t vaginal birth, when does your body realize it needs to start producing or letting down milk/colostrum? Do I need to do anything special besides the standard “latching and just letting baby bring it in”?

What can I expect for recovery week after?Pain?

I’m also freaked at not being able to hold her until I’m closed up and back in room. How long is procedure? How long is baby away in nursery
