I have a newborn baby girl and on the way to delivery it was discovered that it's a breech baby, now she has a breech head. what to do to solve this?

Usually c-section: The head is the largest structure to pass through the birth canal & it would pinch off the placenta providing oxygen during delivery. In most cases breech babies are delivered C-section in the US. In rare cases the OB can do a version & move baby into a head first position, but usually they do it while set up to do the surgery.
