At 20 to 25 weeks gestation, the incidence of breech presentations is 30 to 40%, around 32 weeks this is 10 to 15% while at full gestation, only 3% of babies present as breech. Little is known about the cause of breech positions. It is logical that unborn babies can be in any position in the early stages. They still have a lot of space to swim around. As pregnancy progresses the baby grows larger and its space in the womb becomes relatively smaller up to the point that its space is too small for a spontaneous rotation if the baby’s head is not down yet.
