For me there is no comparison. My first labour was 3 days, 6 hours established ( strong regular contractions baby is on way) but I had no sleep for THREE nights because of the milder contractions.
You don't know whats going to happen at any turn, everything goes well then baby gets stuck and so on. Mine was back to back I felt intense and un bearable pain in my back, I had no idea when or how it would end, would I get her out? Would I be cut? You don't know when the pain will stop it just went on and on and on, every minuet was an eternity...
ELC, I was afraid when I saw the theatre, the staff soon jollied me along, the spinal went in with no issues, and very quickly the baby was out, which was amazing, recovery and ward. It was quick, easy and painless. I didn't have to worry about anything getting stuck or problems, and if something went wrong in surgery I had the staff right there in the room to help me....
You have to know your own personality. I found loo issues really stressful after first delivery, I was crying and sobbing in the shower trying to wash myself, crying on the loo, frightened to drink water and so on. I felt I was lucky first time and got away with a good labour. I hated the aftermath of it down below, it put me off sex for a year. I hated the fear of the un kown, your just in a process that can and does go wrong. For me it was hideous. The tiredness the physical toll it took, the headaches and migranes after all the straining, drugs and lack of sleep had took their toll. Emotionally I was wildly up and down.
With the section I had one nasty burning pain that came and went, it was small fry compared to hours of labour slog. It was perfect for me, perfect ( as perfect as an operation can be!). I came at the baby fresh, emotionally and mentally there, I was able to EBF, bond better and so on. I was pleased my under carriage remained in tact and un scathed too, which was a huge bonus for me.
