Doula selection

We met with a pair of doulas yesterday evening to see if we want to hire them. The gal who we had last time is not doing doula work anymore, so we are searching again. We talked about DS's birth, about VBAC, and what type of things they do. Hopefully we are going to interview one or two more. These gals seemed fine (one of them was our doula's backup last time, so we had met once before), but DH picked up on their frequent references to the other hospital much more than the hospital we will be using. That's not a big factor, but if we can find someone suitable that is more familiar with our hospital's rules and procedures that would be nice.
