here in newzealand it is our choice who delivers a baby. they are refered to as a lead maternity carer LMC, this maybe a doctor, a independant midwife, who you have all visits through during pregnancy and is there for delivery-she may call in a obstetritian if complications arise.
or can go with a team midwife, who is an shift midwife/nurse at the hospital. I would encourage you to look on the internet for what system of maternity care is in your area,
out of 4 deliveries, i found the one and only independant midwife fantastic, very supportive and profesional, All 4 had complications and she was just brilliant.

Ask mums in your area, i feel a independant midwife offers a relationship with the mum, it is a journey over the pregnancy, and knowing someone i feel helps, word of mouth is great.all the best, here a midwife has a 3 year degree,

im also in new zealand, and found the team midwife the best, its meant that if something happens and i cant get a hold of my usual midwife, there is still a midwife on call that can help me.

WE're using a midwife next time... a direct entry one at a birth center. There are also CNM's (certified nurse midwives) who typically work at hospitals. You can get online and see what is available in your area, or ask the person who suggested it. Good luck!
