Which is a 3-year gross motor milestone?

• A. Pedals tricycle
• B. Climbs stairs alternating feet without support
• C. Draws a person with head and 1 other body part
• D. Jumps forward

Answer: (A)

At about three years old, children start showing more coordinated, goal-directed movement, and pedaling a tricycle is a classic example of this level of gross motor development. Being able to pedal requires coordinated use of both legs, balance, and the ability to steer and push off, all of which reflect the advancing motor planning and control typical of a 3-year-old.

Climbing stairs with alternating feet without support tends to come a bit later, as does drawing a person with more detailed body parts, which blends fine motor and cognitive-skills. Jumping forward is often seen earlier or variably, not as specific a marker for the 3-year stage. So pedaling a tricycle best fits the 3-year gross motor milestone.
