At roughly what age does the center of mass reach the navel?

Explanation:
The center of mass moves downward as a child grows because body proportions change—the head and upper body are larger in infancy, and as the legs lengthen and the torso develops, the distribution of mass shifts lower. This downward shift continues with age, so by about eight years old the center of mass in a normal standing position is roughly at the level of the navel. Keep in mind this is an approximate location and can vary with posture, height, and individual body proportions.
