Capable Of Walking Up And Down Stairs, Alternating Feet (27-36 Months)

During their third year, children are in constant motion–running, kicking, climbing, and jumping. They accomplish several major motor milestones during this time period, including alternating feet while walking up and down stairs, kicking and directing the motion of a ball, and standing on one leg (with support). At this age, their running also becomes smoother and more coordinated.
