The stepping reflex (or walking reflex) is a primitive reflex and is present at birth; though infants this young cannot support their own weight. When the soles of their feet touch a flat surface they will attempt to 'walk' by placing one foot in front of the other. This reflex disappears at six weeks due to an increased ratio of leg weight to strength. It reappears as a voluntary behavior around eight months to one year old.
