During a 9-month well check, which finding should the nurse report?

A. Crawls on hands and knees: Crawling is a normal gross motor milestone typically achieved between 7–10 months. This indicates age-appropriate neuromuscular development and does not require reporting. B. Does not respond to own name: By 9 months, infants should consistently respond to their name as part of social and language development. Failure to respond may indicate hearing impairment, delayed communication skills, or developmental disorders, and warrants prompt referral and further evaluation. C. Pulls to a standing position: This is an expected gross motor milestone for a 9-month-old, reflecting muscle strength, coordination, and balance. It is within normal developmental limits and does not require reporting. D. Develops stranger anxiety: Stranger anxiety commonly emerges between 6–9 months and is a normal social-emotional milestone, reflecting attachment to caregivers. It does not indicate a developmental problem and does not need to be reported.
