What behavior might you expect to observe during the evaluation of a 2-year-old child?

A 2-year-old child typically demonstrates developmental milestones that include the ability to drink from a cup. At this age, children are refining their fine motor skills and are often able to handle a cup more independently. This achievement is part of their growth in self-feeding and coordination.

In contrast, other behaviors listed may not align with the typical developmental capabilities of a 2-year-old. For instance, following complex instructions usually requires a more advanced level of understanding and cognitive development that is typically seen in older children. Similarly, engaging in cooperative play, which necessitates social skills and the ability to negotiate with peers, generally emerges later in development. Recognizing colors and shapes might be developing, but it is more common for children slightly older than 2 to confidently identify these without assistance. Thus, using a cup to drink is the behavior you are most likely to observe in a child at that age.
