I didn't have a sense of detachment in my first two labours, but this third labour was different for me. I felt like I had transcended to another level, where pain and anxiety weren't as relevant anymore. It's hard to describe, but it felt like my body and mind just synchronised with the baby's movements and contractions.
I think what helped me get there was the fact that I'd already been pregnant twice before, so I knew what to expect in terms of physical sensations. But also, mentally, I'd prepared myself for this labour by visualising it going smoothly and being confident in my body's ability to birth my baby.
During my third labour, I just let go of all expectations and went with the flow. It could be argued that detachment was a coping mechanism for me at some point during my labour, but it felt more like I'd entered a meditative state where nothing else seemed to matter except for this moment with my baby.
The thing is, I didn't really have time to worry about how intense things were or what might go wrong. There wasn't any intellectualising; it was all just happening at the moment, and everything unfolded naturally. It felt truly magical, like being in a different world.
