Certified Pediatric Nurse (CPN)

A child who knows his first and last name, speaks in 3-4 word sentences, and knows his age is at least how old?

1. 3 years old

2. 4 years old

3. 5 years old

4. 6 years old

The correct answer is: 3 years old

The correct answer is that a child who knows his first and last name, speaks in 3-4 word sentences, and knows his age is at least 3 years old. Developmentally, by age 3, children are typically able to express themselves with simple sentences and start to understand basic concepts about identity, including knowing their full name. At this age, many children can articulate their thoughts using short phrases and are beginning to engage in more complex conversations. Knowing their age is also a common milestone reached around this age, as children develop a sense of self and begin to understand their place in the world. As children grow older, their speech becomes more complex and they begin to handle longer sentences and concepts with greater understanding, but the skills mentioned in the question align with typical development for a 3-year-old.
