Fetus months into the basin

For the first child, generally about 37 weeks of pregnancy began into the labor, that is, about a month before the expected date of birth began into the labor. For the second child, into the labor time later, sometimes even to labor after the beginning of labor. Because the deeper into the basin, the lower the fetal head, the shorter the delivery path, and the deeper into the basin often marks a better head-basin relationship, delivery will be easier.
