A 2-year-old demonstrates a typical developmental milestone. Which behavior indicates appropriate development?

• A. Rides a tricycle
• B. Reads simple words
• C. Runs easily
• D. Builds a tower of several blocks and uses two-word phrases

Answer: (D)

At age two, development is most evident when language is expanding and fine motor skills are showing through simple construction. Using two-word phrases demonstrates expressive language growth—putting two words together to convey meaning shows the child is moving beyond single words. Building a tower with several blocks reflects advancing motor planning and coordination, as well as a growing ability to manipulate objects with purpose. Together, these milestones—two-word speech and stacking blocks—best reflect appropriate development for a toddler. Riding a tricycle is more typical a bit later, reading simple words isn’t expected until school age, and while many two-year-olds can run, the combination of language growth with a block tower is the clearest indicator at this age.
