Which of the following is NOT a 4-year gross motor milestone?

• A. Skips on 1 foot
• B. Climbs stairs, alternating feet without support
• C. Balances on 1 foot, hops, and skips
• D. Draws a person with at least 3 body parts

Answer: (C)

At around age four, kids gain coordination for activities like briefly balancing on one foot, hopping on one foot, and climbing stairs with alternating feet without help. Skipping tends to come a bit later, so a statement that lists balancing on a foot, hopping, and skipping together describes a skill level beyond what’s typical for four years. That’s why it isn’t a four-year gross motor milestone. The other options describe abilities that fit four-year gross motor development (and one option describes a drawing task, which is a fine motor/cognitive skill rather than a gross motor one).
