I am a nurse midwife. Was a nurse first and then became a midwife. Are you in England? The process may be different there. I am in the US. In nursing school, we only had 2 or 3 days on labor and delivery and that was observation only. When I was a brand new nurse working on labor and delivery, I did have the opportunity to catch 2 or 3 babies under supervision in preparation for the times a baby would just come out before the provider got there. As a midwife, I catch...200? babies a year, give or take and some are complicated (Happydaisy~midwives always have to be prepared for the same complications as MDs). Most babies that come fast come easily. A taxicab driver could deliver those ones.

But even nurses have to be ready to deal with complications. I remember a charge nurse about, gosh, 6 years ago?? who delivered a footling breech in the hallway of the hospital....cause it was coming out so what other choice did she have?
Feel free to PM me if you have specific questions. I may be able to add some spice to the character or the situation.
midwife~also struggling through my first novel, but I have the birth scenes down pat!
PS The one thing that makes me

is the focus on clamping and cutting the cord. If the person doesn't know what they are doing, they should leave the cord alone. It's okay if the placenta delivers and the kid is still attached. But screwing up clamping and cutting the cord *could* lead to the kid bleeding out...unlikely but possible and if someone doesn't know that they are doing they should not invite that possibility!
