YAB a bit U
Its not a dig at you because you had a section. First and foremost its just one of those things people say because really, there isn't much else to say about the baby itself. They don't really do much.
Personally i didn't feel id achieved anything due to mode of delivery with my first two, both vaginal, uncomplicated (apart from them being a bit premature at 34 weeks). They were easy births. One 9 hour textbook labour, second 3 and a half hours with six minutes of effortless pushing. Gas and air and diamorphine.
With my third though, a few things happened i had very much feared. He was back to back, they wanted to put that drip in me, i had an epidural because i just couldn't cope. I do feel i achieved something in the fact that i managed to stand up for myself with a horrible snptty doctor who wouldn't take my history into consideration (id only been in labour a couple of hours, and with my second i dilated very quickly, i wanted a chance to do it without the drip and she was horrible).
I feel i achieved something in going through having an epidural - That one terrified me.
I feel i achieved something in carrying to full term finally.
And as for pushing him out, i did feel i achieved something there because at one point I refused to push, i didn't want to do it, it was painful and felt wrong having had two preemies a fair bit smaller. I had no desire to be pushing him out i just didn't have a choice.
If it had ended in a section i would (hopefully) be proud of other things relating to that. TBH consenting to one would take a lot for me to do, i am so scared of them.
I think every woman achieves something (aside from having an actual baby) during birth though for the most part. Whether its vaginal or section.
