I had to have an emergency c-section after my last stage (pushing) of labour wasn't progressing, much to my disappointment!
The spinal wears off quite quickly, in about 2 hours I could feel the sensation returning to my body. You do shiver a lot though, it's horrible!!
I had a fairly major bleed, so it took them over an hour, but as everyone else here has said you don't notice the passage of time. They held my daughter up so I could see if it was a boy or girl (I asked) and then took her to the side table to get her breathing, which she did in less than 60 seconds. I couldn't see her then, but hubby could. They then weighed her, measured her and I could see her the whole time. Then they brought her over to my hubby & I, all wrapped up in a white towel. They didn't put her on my chest or anything, but I was able to stroke her with my one hand (other one had a drip in it).
When they had finished operating on me, my hubby went with her while they took me through to recovery. From then on we were never apart.
HTH.
