A nurse is assessing a 6-month-old infant during a well-child visit. Which of the following findings should the nurse report to the provider?

A. The infant does not exhibit fear of strangers: Stranger anxiety typically develops around 6–8 months, so not showing it at exactly 6 months is not immediately concerning. B. The infant does not roll over from their abdomen to their back: By 6 months, an infant should be able to roll over. Failure to achieve this milestone suggests a delay in gross motor development and needs evaluation. C. The infant does not pick up objects from the floor with their fingers: Fine motor skills such as using fingers to pick up small objects (pincer grasp) develop around 8–9 months. D. The infant does not sit on the floor unsupported: Sitting unsupported typically develops between 6–8 months. At 6 months, it may not be fully achieved yet, so it’s not necessarily abnormal.
