Based on a child's ability to state her first name and express desire to leave during an assessment, what is her estimated age?

The correct answer reflects developmental milestones that are typically observed in children around 30 months of age. At this stage, children usually begin to exhibit more advanced verbal skills, including the ability to articulate their name and express desires or preferences verbally. This indicates a growing vocabulary and an increased ability for self-advocacy and social interaction.

By 30 months, a child is often capable of recognizing and stating their first name, as well as showing an understanding of basic concepts related to their personal environment and desires. The capacity to express a wish to leave during an assessment indicates a growing sense of agency and understanding of their surroundings, which is consistent with the developmental expectations for children in this age range.

Younger children, such as those around 24 months or even early 28 months, may still be developing these language skills and may not consistently demonstrate the same level of verbal expression or understanding. Meanwhile, children closer to 36 months would typically have a more advanced skill set, which may go beyond simply stating their name and expressing such desires. Thus, the age that fits best is 30 months, where these language and social skills begin to emerge more clearly.
