@lisajcoleman1 Speaking as a twin mom and anesthesiology resident who provides labor and delivery anesthesia,
please only take the advice of maternal fetal medicine obstetricians with this delivery - no one on the internet can tell you what is safest for your baby's particular position, or what the OB covering your delivery is comfortable managing. For example, some OBs have experience attempting external cephalic version for twin B after twin A is out. Others don't. It only make sense to try this with someone who has experience and can do it safely.
Also, even if planning for vaginal delivery, plan to deliver in an operating room at a hospital with an on-site NICU. Twin vaginal deliveries need to happen in an operating room where a STAT c-section can happen in minutes - the exit of twin A may cause immediate complications for twin B like cord prolapse where the umbilical cord gets kinked in the vaginal canal. There is no way to prevent or predict immediate complications like this even in the healthiest of twin pregnancies.
Please also get an epidural for your labor. The epidural isn't just for pain management - it's a way for a c-section to happen so much faster and more safely for mom and babies than crashing into a fully asleep c-section. Epidurals can be dosed with big gun numbing medications such that mom can be ready for a stat c-section in minutes, and minutes matter when the babies are crumping due to in utero issues. Imagine being without oxygen for 5 minutes vs 15 minutes. BIG DIFFERENCE.
That said, DEPENDING ON BABY'S PRESENTATIONS, vaginal delivery can be a safe option for twin birth. I had mine vaginal at 38+4 and it went well, albeit with a 3 liter hemorrhage that would have killed me if I'd been at home. Being in a hospital that could manage complications saved my life, and enabled me to go home the very next day feeling well.
In making your decision, please please get your advice from high risk maternal fetal medicine obstetricians, not from anecdotes. Things can go to shit very quickly in deliveries. Just yesterday morning I did a c/s for a triplet pregnancy where one baby died in utero and the others were delivered at 24 weeks. They were tiny and will be lucky to make it through without severe life long medical complications, if they even survive at all.
I wrote up my own birth story in a previous post. Wishing you a smooth delivery!
