Which would most likely be an indicator of atypical motor development in a three-and-a-half year old child?

• A. The child is unable to skip across the room.
• B. The child cannot throw a rubber ball overhand.
• C. The child is unable to build a tower of eight blocks.
• D. The child cannot walk downstairs using alternating feet

Answer: (D)

Grasping how young children coordinate movement helps identify when something isn’t developing typically. By about 3½ years, many children can descend stairs using alternating feet, which shows balance, leg strength, and the ability to sequence movements smoothly. If a child cannot walk downstairs using alternating feet at this age, that difference points to atypical gross motor development because it reflects a specific, age-expected coordination skill that should be emerging around now. Other options describe skills that are either more advanced for this age or vary widely among children. Skipping across the room is usually mastered a bit later, so not skipping isn’t as strong an indicator at this age. Not throwing a rubber ball overhand and not building a tower of eight blocks can be delays in fine motor skills or early motor planning, but these don’t as clearly pinpoint a broader gross motor coordination issue as difficulty with descending stairs using alternating feet.
