I asked a lot of questions. I carried a notebook around writing things down to ask the midwives. These are some things you might want to ask about.
fees/insurance
lab work, tests, sonograms, doppler, etc
the midwives' experience (how many births attended? transfer rates? maternal/infant mortality rates?)
water birth, lotus birth, placental encapsulation
other moms due around my due date?
how clean/big does my house need to be
pets or children at the birth or home visits
preventing tearing
belly casting, rebozo work, other ceremonial work
emergency procedures
birth kit, tub rental, birth stool, other supplies
recommended reading
tips for morning sickness
I also asked a lot of just nosy personal questions, to try to see if this would be someone I could be comfortable and secure with. I asked about the midwives' own children's births, where they went to school and worked, why they became midwives. I also asked a bunch of questions about how they would act/react in response to my own wishes, like, "If I yelled at you rudely, would you be OK with that, or would you be offended?" and, "If we make this plan for massage and then I don't want you touching me, will that bother you?"
They seemed to appreciate my frank honesty and we actually hit it off great.
