Isa, here are the questions we asked providers during first interviews:
-What's your experience with twin clients? How many of them deliver vaginally? Planned c-sections versus emergency?
-What positions do you require the babies to be in for a vaginal birth? If baby B is breech, will you attempt an internal version, or a breech delivery?
-Will you allow me to deliver in Labor and Delivery, or do all twin births happen in the OR? Under what conditions might we deliver in L&D?
-Do you require an epidural during labor for your twin patients? Do you require continuous monitoring? An IV?
-Will I be able to labor in the birth tub before delivery? Eat? Drink? Move around as needed?
-How many people are on call for births? What are each of their philosophies on twin births?
-What do you consider "full term" for twins? Assuming a healthy pregnancy, how long will I be allowed to carry the babies?
-What is your schedule for ultrasounds, non-stress tests, and other monitoring throughout my pregnancy?
I will tell you that we blew through 3 OB practices in our town before giving up and going one town over to work with midwives at the other hospital. Many of the OBs I talked to would not consider letting me go past 38 weeks, insisted on delivering in the OR, insisted on an epidural (just in case!), and wanted a huge amount of monitoring. The midwives we ended up with were backed up by OBs, had lots of experience with high-risk pregnancies, but were a lot calmer about everything. I went into labor on my own at 38.5 weeks. I was lucky enough to have both babies head down, so they let me labor and deliver in L&D. I was able to labor in the tub for several hours (though they would not let me birth there). In the end, I opted for an epidural (which actually helped things along), but they were fine with me not having one. The thing that gets tricky in larger practices is that not everyone will be on the same page about these questions. Don't be afraid to keep asking!
