At 16 months of age, which developmental milestones should a child typically be demonstrating?

At 16 months of age, it is typical for a child to be developing fine motor skills and self-feeding techniques. Using a spoon and cup with occasional spilling is a common milestone at this stage as children are becoming more adept at handling utensils and managing drinks. This skill indicates a growing understanding of how to manipulate objects and reflects the child's increasing independence in feeding themselves, which is a crucial aspect of development during infancy and toddlerhood.

Using 10-12 words consistently is generally expected a bit later, around 18-24 months, as language development accelerates during this period. Following complex commands is typically observed after 24 months, as it requires a higher level of cognitive and language skills than a 16-month-old usually possesses. Riding a tricycle is a skill that usually develops around 3 years of age when children have gained the necessary coordination and balance. Thus, the correct answer highlights a developmentally appropriate achievement for a 16-month-old child.
