I had one thanks to Yvette and was glad that I did. I wanted a natural birth (doesn't everyone?) but ended up with an emergency caesar after 20 hrs and only getting to 3cm as the cord was around Amy's neck twice and her HR was dropping. My waters broke first so I had to deliver within 24 hrs because of the risk of infection. The midwives and OBs had read and understood my birth plan and held off inducing me for as long as possible and did not push me to be induced at any stage. Also, I was adamant that I was not having Pethadine and was not offered it because it was clear on my birth plan. In my plan I had a section on caesareans if required so I was not stressed at all that it happened and did not have regrets because she had to be born this way or she could have died or been brain damaged. So I am all for them but everyone is different.
