1 Your baby floats in your uterus and changes positions often throughout early and mid-pregnancy. 2  When you're between 32 and 36 weeks pregnant, your baby usually rotates to a head-down position for labor and delivery. 3  Head-first position is called the vertex position. 4  Feet-first position is called the breech position. Your baby already might have settled into a head-down position in your pelvis, if this is your first pregnancy. 2  This is the ideal position for delivery because your baby's head is the biggest part of her body.
