How do you turn a baby during a breech birth?

With difficulty: Sometimes an obstetrician will try a "version" maneuver in early labor, but this is risky. If the baby has descended partly into the birth canal it is unlikely to change position. The maneuver also has some risk of causing part of the placenta to separate. This would often only be attempted as a last event, before taking mom to the OR for a c-section.
