During a routine health examination, a parent expresses concern that their 15-month-old child is not yet walking independently. Based on knowledge of typical developmental patterns, how should the medical assistant BEST respond?
Suggest that the parent engage the child in structured walking practice sessions daily.
Reassure the parent that it is within the normal developmental range for a child to begin walking independently by 18 months of age.
Advise the parent that the child is showing signs of a developmental delay and needs intervention.
Recommend immediate referral to a pediatric orthopedic specialist to rule out any underlying conditions.
