The most common symptom of IUGR is the baby being smaller than expected during the pregnancy and at birth. Antenatal small for gestational age (SGA) is defined as fetus with weight <10th percentile. As water erodes a path from its headwaters to its mouth at a standing body of water, it tries to cut an ever-shallower path.This leads to increased erosion at the steepest parts, which is headward erosion.
