Certified nurse midwife vs ob?

Emily
My hospital offers the option of having an ob gyn or CNM oversee prenatal/labor & delivery for low risk pregnancies. I know I want a hospital birth 'in case' -and I like a lot of what I'm learning/researching about CNM s and am considering that route since it seems to be a great blend of what I'm looking foR. Anyone else using a nurse midwife in a hospital? Or used one w a previous pregnancy?
