Which development milestone is expected at eighteen months?

At eighteen months, a child is generally expected to demonstrate significant motor skills, which include walking and the ability to drink from a cup. By this age, many toddlers have developed sufficient strength and coordination to walk independently and have also begun to refine their self-feeding skills, which typically involves handling a cup.

The other options reflect developmental milestones that either occur at different ages or require skills that are typically advanced for an eighteen-month-old. Selecting objects by color is usually seen around two years of age, drawing small shapes often emerges later, and running and jumping generally develops after the age of eighteen months, as those skills require more advanced physical coordination and balance. Thus, walking and drinking from a cup aligns well with the typical developmental trajectory expected at eighteen months.
