Nope, I won't bother doing a refresher. Last time they were so busy that the only course I could get on was a one-day job and the room was so small we weren't allowed to bring partners 
The MWs who ran it were really nice, but I learned nothing I didn't already know from the internet, tbh, although I remember a physio came and spoke and it was interesting to hear from her. A consultant came in to talk about pain relief and he did a lot of heavy sighing and listing out the perils of epidurals while at the same time mentioning that the many first-time mothers opted for them. I came away vowing to not get an epidural, whatever else I did (and then I got one, go figure).
As in Random's experience, there was nothing at all about the post-birth stuff! All of my frenetic research had been based on prepping myself for labour
but there really should have been more about feeding* and even basic stuff like what exactly to dress the babies in.
Thursday I was so with you on the needing to know the gory details about pooing and vomiting in labour. I actually was fixated on this. I did not want to poo everywhere in front of my DH. I remember I was in the hospital bath and decided I needed to poo and ordered DH out of the room...then got really upset because the necessary clearout was not forthcoming it came later.
*They usually need feeding way more often than you'll be told by your healthcare providers!
