A nurse in a clinic is assessing a 7-month-old infant. Which of the following indicates a need for further evaluation?

A. Babbling one-syllable sounds is appropriate for a 7-month-old infant and indicates typical language development. B. Using a unidextrous grasp (using only one hand) could indicate a preference that needs further evaluation. At this age, infants should use both hands equally, and a strong preference for one hand might signal neurological concerns. C. Fear of strangers is a normal developmental milestone that typically appears around 6-8 months of age. D. Showing preferences towards foods is typical as infants begin to develop tastes and preferences during the introduction of solid foods.
