My first baby was a c, and I tried to schedule my second child as a c, since I had a lot of issues going on, and a four day hospital stay sounded a lot like a vacation at the time, but my doc said no. (She always encourages her v-bac candidates to start out on labor first, and then goes to a c only if it turns out to be necessary.)
I suppose you have both the advantage of knowing exactly when your baby is coming, but the disadvantage of all of the "what-ifs." And that's fair, what-if's happen. But, what-ifs can happen in both situations. Right now, take a minute to think out all of your specific what-ifs. Figure out what you can do about it. Write out a medical directive if you want to. Do whatever you can to make the list seem less daunting. Then, write everything down on a different list, that you can't do anything about. Do you have a fireplace? If not the kitchen sink will do. Now, burn that second list. It's gone. (Yes, I know, not really, but it works mentally for me, anyway.)
Now go back to the advantages, and have fun with this list. First, it will certainly be easier to schedule grandparent visits this way, as well as care for your older children. You won't be surprised at having to go the hospital with an unpacked bag. You'll have the nursery ready. You can have meals prepped in the freezer. And there are other advantages to a c, too. Less, um, swelling. It'll be hard to get up while recovering, but easier while you're sitting. And, hey, try and get someone to help out around the house while you're in that longer recovery. (I mean, you really shouldn't be vacuuming anyway, right?) In a c, the doc generally clears out as much "debris" as possible, but with a vaginal birth, well, heavy flow for a few weeks. Ask anyone to be truly honest, and the "fourth trimester" sucks either way, but both birth methods have their advantages, too. I assume you've already thought out quite a few of them, to have made a firm decision. Dwell on those.
Congratulations!
