The ideal fetal position for labor is when the fetus is head down, facing your back, with its chin tucked to its chest and the back of the head ready to enter your pelvis. This is called cephalic or occiput anterior presentation. Most fetuses settle into this position by the 36th week of pregnancy.

Occiput anterior is usually the easiest position for the fetal head to traverse the maternal pelvis. Shown here is the "direct OA" position. While some fetuses deliver in this position, others deliver slightly rotated clockwise (LOA) or counterclockwise (ROA).
