Accurate assessment of developmental domains is critical for identifying delays that warrant early intervention. Match each of the following documented developmental profiles to the chronological age at which a typically developing child is expected to achieve these specific milestones.
- Profile: Uses a spoon with some spilling, stacks 4 blocks, walks up stairs with one hand held, and speaks approximately 15 words.18 months of age
- Profile: Hops on one foot, copies a cross, engages in cooperative play, and speech is completely intelligible to strangers.48 months (4 years) of age
- Profile: Copies a triangle, skips with alternating feet, draws a person with 6 distinct body parts, and dresses independently.60 months (5 years) of age
- Profile: Rides a tricycle, copies a circle, speaks in 3-word sentences, and begins taking turns during play.36 months (3 years) of age
- Profile: Sits with pelvic support (tripod position), transfers objects between hands, rolls from back to front, and babbles using consonants.6 months of age
Answer
The 18-month profile stacks 4 blocks; the 4-year profile hops and copies a cross; the 5-year profile skips and copies a triangle; the 3-year profile rides a tricycle; and the 6-month profile sits with support.
Each chronological age corresponds strictly to a classic constellation of gross motor, fine motor, language, and social milestones. Recognizing the synergistic development across all four domains allows for accurate age matching.
