A nurse is assessing a 2-year-old toddler. Which of the following findings should the nurse expect?

A. By age 2, the chest circumference typically equals or slightly exceeds the head circumference (head circumference is larger at birth but becomes proportionate as the child grows). B. A protruding abdomen is normal in toddlers due to immature abdominal muscles. C. Deciduous teeth (baby teeth) are not naturally lost until around age 6 when permanent teeth begin to erupt. D. Fontanels should be closed by 18 months, so they should not be palpable in a 2-year-old.
