As the fetus develops during pregnancy, women belly grows farther out in front of them with tightening surrounding force. This c back curve it bent beyond they can by them self. Therefore, the lordotic curve (inward curve) of the spine becomes more pronounced. This increased lordotic curve then changes how the spine bends forward. Now, because of its new shape, the vertebrae don't get to flex as much as they used to when bending forward; instead, they remain in some extension. This new curve make the butt look really big and not that they actually grown any big.
