I would not call my first birth traumatic.
But I empathize with a lot of the feelings being discussed in this forum, and its so worthwhile, particularly on this site, because I think there is a lot of shame being felt when the natural birth doesn't turn out so natural.
My first pregnancy was lovely. Though my DD was breech, and we tried EVERYTHING to turn her, ended up shceduling a c-section...
then...
the day before, she TURNED!

:
So the C was cancelled, we were back on the natural track. My midwife was excited, we were excited. Everything was go.
Fast forward 3 days, my water broke, and more than 24 hrs later, after hours & hours of hard back labor, oh god the pain!, consenting to an epidural that I didn't really want because I felt somehow like I'd be FAILING if I didn't go all natural (that is beyond dumb, but I'll tell you, it is pervasive on this site - we've got to work on changing th culture of shame in realizing sometimes all natural PLANS don't work out - there is a reason and a time to use medicine to help), the epidural didn't work. Neither did the subsequent one. So I kept fighting through the labor which was still ungodly painful, only now my legs weren't fully functioning, and I pushed for hours. DD was stuck. Forhead presentation - my midwife could see/feel her eyebrows, but my cervial lip was swollen and so though I'd been at 10 cm for hours, DD couldn't decend all the way. I was running a fever. They were worried about merconium. DD was delieverd by C-section 31 hours after my water broke. And honestly, the surgery wasn't so bad. Really it wasn't. What was rough, was being immediately separated from my baby for an hour while I was sewn up. Barely got to see her. That was the worst part for me. That, and we were in the hospital for a week because she had severe jaundice (from a blood incompatibility with me), my milk wasn't coming in, she was colicky from the moment she was born, I was completely thrown for a loop. Fortunately, she turned into a champion nurser, I healed amazingly well from the surgery, her bili numbers started to come down, and all was well.
Next birth, we were SO determined to do it "right". Hired a doula, did prenatal yoga, read everything I could on succesful VBACs, had another relaly well thought out natural birth plan. But the difference was this time that I ALSO planned for the things that the first time around I never thought would happen - because I was under the crazy impression that if you just BELEIVED enough & WANTED enough & PLANNED enough to have an all natural med free, perfect birth, you'd get one. This time I was ready for ALL the possibilities. And that made such a difference. Allowing myself to think, while not in the midst of contractions, about major decisions involving meds, etc., was so important.
So when my son was born via emergency C a month ahead of time, even though it was completely unplanned, and a scary surprise, I was okay, and it was a beautiful birth! We had a plan for the possibility of another C - and insisted on my husband being in the room for the insertion of the spinal. We insisted on my son being placed on my chest immediately after birth while I was being sewn up. Insisted on no separation, and we were PREPARED this time for severe jaundice (which he also had)... and were able to go home at day 3, not day 7 - and treat him at home with home health nurses & a bili blanket. And what a difference.
Anyhow yeah, if you made it this far, thanks for reading.
The answer to the question is yes, my second birth was much easier emotionally, because I didn't have that underlying sense of "failure" - that I did something wrong, or could have done something different that would have made the "ideal" birth possible, or changed the course of my second birth. The truth is, I did
everything I could (and I believe this NOW about my first birth as well). My second pregnancy & birth was SO healing, and really helped me through the feelings I carried from my first pregnancy & birth. Not everything in life is plannable or controlable - particularly pregnancy, childbirth, and parenting! But it makes sense to be educated and prepared for all possibilities, on paper AND emotionally.
I highly recommend reading Birthing from Within by England. It helped me so much in my second pregnancy.
