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,
