With every passing day of your pregnancy your baby grows develops and moves inside your womb preparing itself for labour and birthing. So as you near your expected delivery date your baby would position and align itself along the birth canal in such a way that its head would be facing down placed in the pelvis area of the mother. Your baby takes this position a few weeks before the delivery to gear up for a natural birthing. As in the process of natural birthing the head of the baby comes out first marking the grand entry into the world.
