The second one is soooo much easier in my experience. You know what to expect, you aren't panicking (I was in labor during my first and I was in so much pain). I hate that I've had them, but if you have to have a second, there are so many advantages of planning it,rather than having a rapid,unplanned one. You'll likely have a spinal block, get to hear your babies first cry (this was always my boohoo moment) and get to see baby right away.
That happened to me too. I was so upset I had to be put out. My second scheduled was a breeze a it worked and was able to hear my beautiful baby boys first scream and it was the best thing ever :-D having my 3rd in may and can't wait!
