What is a developmental skill that can commonly be expected at 18 months?

• A. Can kick a ball
• B. Can stand on one foot
• C. Can stack 6-7 blocks
• D. Can throw a ball

Answer: (D)

At 18 months, a child is typically developing gross motor skills that include increased coordination and the ability to engage in basic play activities. One of the milestones observed at this age is the ability to throw a ball. This skill reflects the child's emerging physical capabilities, such as throwing actions that require an understanding of arm and hand movements as well as aiming.

Throwing a ball at this age doesn’t need to be precise; it can often be more about the motion and intent rather than the outcome. This activity not only demonstrates motor skills but also promotes social interactions and play, which are essential for cognitive and emotional development.

While other milestones, such as kicking a ball or standing on one foot, develop around this age, they may not be as consistently expected as the ability to throw a ball, which is a fundamental activity stimulating early physical and social development. Stacking 6-7 blocks is more characteristic of a slightly older age, as it involves fine motor skills and hand-eye coordination that typically become more refined after 18 months.
