Oh, absolutely. But maybe not in the way you think.
My first birth was traumatic to me. I was 17, and ended up with an emergency c/s under GA following a failed ventouse (with episiotomy - which any midwife or obs would tell you, should not happen. No epis unless baby is coming. Mine clearly was not).
I spent 10 years adamant I was going to have the birth I should of had first time, if only I had known more when I was not a midwife.
I started my training at 19, so my DS was 2 and the birth very raw still. I did end up going back to the unit I gave birth in for a labour ward placement and worked with the midwife who had cared for me in labour, along with some other midwives who had been less than pleasant towards me. I found that really tough. Luckily it was just one 8 week placement and I didn't go back in to the unit again. We trained at more than one hospital.
It didn't affect me day to day, but as a plus point from it all I do feel that I have more confidence in standing up for a womans choice. Just because it is a guideline, it doesn't mean one size fits all. Some midwives have found it tough to challenge guidelines in respect of a womans wishes.
Anyway, my DS is about to turn 20. I no longer feel traumatised, and am 100% over the trauma of his birth. It didn't happen until I had my second DS 10 years later though. Once I had been through a birth where I felt I had some control and choices, it just helped heal all my guilt and shame at feeling my body and mind betrayed me.
So I suppose yes, our stories will shape how we are as midwives. For me I've never felt envious or resentful. I find that other peoples births are more likely to come back to haunt me than my own. There are some births, some women, and some stories that will stay with you forever. And from time to time I'm reminded of those.
