From what I remember re: the catheter - I had mine taken out the following day and given a shower as well. I don't really know about the epi as it didn't work with me and they had to do a morphine spinal block (or something along those lines) so there wasn't actually anything left in me (except there was tape on my back for some reason?!?) strange.
My sister had a c-section 2 weeks ago in the morning, and I think they let her get up in the arvo. But it was her 4th - so she's pretty stubborn and probably just wanted to get up herself
