A 9-month-old girl from Delhi is brought to the pediatric clinic by her mother for developmental assessment. The child was born at term with an uneventful perinatal history. On examination, the child sits without support, transfers objects from one hand to the other, says 'mama' and 'dada' non-specifically, and shows stranger anxiety. She pulls herself up to standing by holding furniture but does not cruise. The mother reports the child feeds herself with a spoon with some spillage. What is the MOST appropriate developmental assessment for this child?
