I think that in some cases there is call for repeat c-sections.
I had a horrific first birth which, after 36 hours of labour reaching 7cm dilated, culminated in an emergency c-section, 4 pint blood loss (most of which was lost prior to the section) And a baby in special care as he wasn't breathing.
When I had my second I had genuine panic attacks and flashbacks when I returned to the hospital. Therefore I asked for a second c-section, I moved hopsitals too to avoid the feeling I got when I was on the orginal labour ward. I was actually terrified of going into labour and having to go through what I went through again, I had my second c-section without any trauma and my son was perfectly healthy.
I think making sweeping statements about repeats being wrong is a mistake, in each case specific circumstances should be considered, in my situation to trauma of the first experience was too much.
I'm not having a go, I just wanted to voice my opinion, I didn't choose a section because it was easier I chose it because it felt like the only option for me.
