Which is a typical gross motor milestone in early childhood?

• A. Scribbling
• B. Walking by 12 months
• C. Stacking blocks by 2 years
• D. Drawing a circle by 3 years

Answer: (B)

Gross motor development covers large-muscle movements like walking, running, and jumping. Walking by about 12 months is a classic example of a gross motor milestone because it shows the child has gained upright balance and mobility, laying the foundation for later big-movement skills. Scribbling, stacking blocks, and drawing circles are mainly fine motor tasks that rely on precise hand and finger control and drawing or manipulating small objects, and they typically emerge a bit later or alongside other fine motor skills rather than as early gross motor leaps. So walking by 12 months best fits a typical gross motor milestone in this developmental window.
