I'm sorry the baby hasn't turned yet.
I don't know which would be best for her post-partum mental health - knowing she did everything she could to turn the baby, or getting ready for a c-section beforehand? Maybe a mix of preparing herself for any eventuality, coupled with still doing everything she can to encourage turning, would be best. Of course, I'd personally prefer the third option, birthing the breech baby vaginally if s/he doesn't turn. You have to try hard these days to get a vaginal birth with a breech baby, but it should still be HER CHOICE, not the only thing her doctors will "let" her do! She shouldn't be forced into a c-section, even if she has bad doctors... *sigh*. I guess it depends on what she's open to trying. But if she should decide she's open to the idea (whether that's finding a breech-experienced OB, midwife, going in pushing and refusing the c/s, or just UCing), she'll find all kinds of support here.
