Capable Of Standing On One Foot For Up To Five Seconds (39-47 Months)

By age 3, preschoolers have developed enough motor skills to participate in organized games and some sports. They are now capable of hopping and standing on one foot for as long as five seconds, although this demands more concentration than routine activities like walking and running.
