By 36 weeks of pregnancy, most fetuses turn into a head-down, or vertex position. This is the normal and safest fetal position for birth.
A fetus with the feet, buttocks, or legs pointing down toward the cervix is said to be in breech position
The buttocks are down near the birth canal
buttocks are in place to come out first during delivery
One leg (single footling) or both legs (double footling) are stretched out below the buttocks. The leg(s) are in place to come out first during delivery.
