DD was an undiagnosed frank breech (her feet were by her head). They only noticed when I was about 7cm dilated and I quickly got to 8cm as I was signing forms for the ECS, and ended up with a vaginal birth.
Someone upthread asked if vaginal delivery is an option for breech babies. It is, but many midwives don't have much experience of it, so there is often encouragement to opt for a section without discussing the reasons for it. To be honest, I was a first time mum and I was all for following advice to have a section, so I'm not dissing anyone for having a section, esp as i only found out all of this later.
Apparently, the reason they encourage sections is because usually once the head has been delivered, the birth canal tightens around the body to deliver it quickly. All well and good when baby is the right way round, but if the baby is coming out slowly and is breech, he/she might have restrictions on their breathing ( NB- I am not a doctor, and am only recounting my recollection of DD's arrival ). Oh, and I had a really big episiotomy, which again apparently is normal with breech babies, to make sure there's enough room to get the head out easily. DD arrived 72 minutes after we got to hospital, so speed wasn't a concern for her.
Good luck, whatever you decide.
