I want a midwife who networks with other birth professionals, has other midwives she can call if she has two clients in labor or is stuck at a really long labor, and keeps up with continuing education. I want to know she has experience with some complications such as hemorrhage, shoulder dystocia, etc. I realize some complications are so rare that she might not have seen them, but I would want to know she has a plan for how to manage them.
A back-up OB or hospital based CNM is a plus.
Those are things I considered when choosing a midwife. :)
