Re: Homebirth...what to ask the midwife?
In an email, I would simply ask for a live appointment where the two of you could meet to see if it is a good fit for you to work together. In phoenix, all the midwives offer this service for free, so that may be true in your area.
Then, when you are together, you can ask all the above questions AS WELL AS figure out if you actually like her/trust her/bond with her.
I wouldn't ask anything in an email about birthing procedures, etc b/c you can't get a sense for attitude, tone
