1. During a routine developmental assessment of a 4-month-old infant,

which milestone would the nurse expect to observe?

 A) Sitting without support

 B) Rolling from back to stomach

 C) Babbling and cooing

 D) Pincher grasp development

 Answer: C) Babbling and cooing

 Rationale: By 4 months of age, infants typically engage in babbling and
