A young boy recently adopted from an international orphanage is brought to the clinic for a comprehensive initial evaluation. The adoptive parents do not possess his birth certificate, but the adoption agency estimated his age to be "around 2 years old." The parents are anxious to know if his development is appropriate for his estimated age.
During the assessment, the physician observes the child exploring the exam room. He runs stiffly and falls occasionally. He is able to walk up the clinic's step-stool when holding the physician's hand. When given wooden blocks, he successfully builds a tower of exactly 4 cubes before it topples. He is also given a crayon and spontaneously scribbles on the exam paper. His parents report that he uses a spoon to feed himself, though he often spills.
Based on the child's demonstrated motor and adaptive skills, which of the following communication or social milestones is most consistent with his current developmental age?
- ACombines vocabulary to formulate two-word phrases
- BFollows a two-step verbal command without gestures
- Engages in simple pretend play, such as feeding a toy dollAnswer
- DEngages in parallel play alongside other children
- EIdentifies his own age and gender when asked
Answer
This patient's developmental age is 18 months based on objective clinical findings, despite the historical estimate of being 'around 2 years old'. Developmental assessment requires cross-domain correlation, and physical exam findings must supersede unconfirmed historical estimates.
At 18 months, expected milestones include:
- Gross Motor: Walking independently, running stiffly, and walking up stairs with a hand held.
- Fine Motor: Building a 4-cube tower, scribbling spontaneously, and using a spoon/cup with some spilling.
- Language: Speaking 10-25 words and pointing to one or more body parts.
- Social/Cognitive: Engaging in simple pretend play (e.g., feeding a doll, 'talking' on a toy phone) and pointing to show shared interest (joint attention).
Because his motor and adaptive skills firmly place him at an 18-month developmental age, the expected social milestone is simple pretend play.
