Pain is subjective so it really makes no sense. I've never experienced any pain worse than my labour and I can't imagine I ever will. Having 22 bones broken or being burned alive sounds like a welcome alternative to me
Also the length of time, having 22 bones break would be pretty quick, some women's labours are epically long and can be unrelenting, I had short labours which makes it much more manageable. I would never say to anyone is is easy or not "too painful" it depends on the woman, the position of baby etc etc.
Also, it would be interesting to see the response in baby club vs toddler club, I think we would get much more painful memories from baby club on the whole the memory of pain in labour dissipates with time, if you asked me 4 months ago I probably would have said worst pain ever, now I wouldn't. Other women probably have much clearer memories of it!
