Why do feet stand in a figure of eight and legs are straight?

Toddling and standing too early. Because children's legs are not strong enough, when they learn to walk and stand prematurely, their feet will naturally separate, so that the area of the soles of their feet will become larger, so as to stand firm and prevent falling, thus resulting in natural splayed feet. Script meaning refers to the calf, that is, the part from the knee to the ankle, and later refers to the foot, that is, the part below the tibia that touches the ground, extending to the lower end of the object.
