I can see the argument you're making, but for me personally, no, I didn't feel dissociated from the process.
But then my two experiences of labour were really like night and day. The first time it was the classic induction which stalled at 5cm and ended up as an emergency C-section and yes, that time I did feel like I wasn't really playing an active role in my own labour. I felt disappointed that I hadn't been able to experience spontaneous labour and guilty about all the conflicting feelings I had. Had I let myself and my baby down by not trusting my body to know when the time was right? Did I imagine the reduced movements because I was too scared? Or was I making a big fuss over nothing because the most important thing was to get my baby out safely? I felt like my baby's birth was something doctors did to me rather than something I did myself, and I felt sad about that. The epidural was really neither here nor there though. It provided welcome pain relief at the time and I don't honestly believe it changed the outcome.
The second time round I was desperate to experience spontaneous labour and a vaginal birth because of what had happened the first time. And honestly, it was magical. I was so happy and excited when I went into labour, feeling like my body was actually doing what it was supposed to be doing. I spent most of the night in the bath tub with essential oils, listening to music and breathing through the contractions, and although I don't think that particularly helped to move things along it was a nice experience. But because we had already decided that I would get an epidural at some point, I asked for it at the moment the contractions started to get stronger and I was starting to feel like I wasn't really enjoying the experience anymore. At that point I was moaning a little bit during each contraction but nowhere near screaming in pain or anything like that. Because the epidural was lightly dosed it just took the edge off. I could still feel that I was in labour and that things were progressing, but I was able to rest a bit. Still got the urge to push, still got the euphoria when my baby was finally born.
I do think that maternity care here is more woman-centric, for example, each woman getting free pelvic floor physiotherapy after each birth, longer hospital stays but with much better food and never more than two women to a room, for example. And I genuinely think the belief that proper pain relief should be offered as standard is part of that overall philosophy. I'm now extremely mistrustful of the NHS's attitude to this. Because it's not just making women fearful of pain relief or telling women who have asked for an epidural that they don't really need one, or they will have to wait, or it's too early, and oops, now it's too late. It's also sticking new mothers on postnatal wards with seven other women and their babies and their male partners who snore and watch YouTube with the sound turned on all night. It's not feeding women who have just given birth at the "wrong" time and making them wait until the next mealtime. It's expecting women who have just had a C-section to get up and walk to where the food is being served, or to visit their babies in the NICU, and not giving them any assistance if they can't do that. It's not having anyone on call to help women with a fresh C-section incision lift their babies out of their cots for night feeds. It's women who have been hospitalised with gestational diabetes not being offered any suitable meal options which will allow them to keep their blood sugars under control.
Sorry, that was a bit of a rant. I just think they could do better, but they don't, because it's just women having babies, which women have been doing since the beginning of time and they should stop making such a fuss about it.
