Back to breech at 35 weeks

Charity • Wife. Mom of both💙💗. Currently pregnant with twins🤰🏼.

Any of you twin mamas have baby B flip from head down back to the breech position at or around 35 weeks ? If so , how did baby flip back to head down before delivery or no?

My OB says she’s comfortable delivering baby B breech as long as baby A is head down but I’m not sure I’m comfortable with that given the risks..
