 They believe that based on the markings from the first born, the sex, number and interval of future births can also be foretold.The most important markings are that of a future shaman (worms or flies clutched in the fist of a newborn), midwife (white mantle over the head, which comes from the amniotic membrane) and a baby that will endanger the survival of future siblings (born with a double whorl in its crown).The midwife is the first to see the infant and before a mother can bond with her baby, the midwife is expected to carefully interpret the signs that the child bears, and she alone will interpret what profession the child is destined for.
