At what age do children typically express stranger anxiety?

1. 4 months

2. 6 months

3. 8 months

4. 10 months

The correct answer is: 8 months

Stranger anxiety usually develops around 8 months of age. During this time, infants begin to recognize familiar faces and exhibit distress when encountering unfamiliar individuals. This emotional response indicates a developing attachment to caregivers, as children become more aware of their social environment and those who are part of their everyday experiences. The emergence of stranger anxiety is an important milestone in social and emotional development, reflecting a growing understanding of security and trust. Infants around this age may also demonstrate separation anxiety, leading to discomfort when separated from their primary caregiver. This behavior typically peaks between 8 to 12 months and gradually diminishes as children become more secure in their relationships and develop better social skills. While some children may show signs of wariness toward strangers as early as 6 months, the majority experience a more pronounced form of stranger anxiety beginning at 8 months. It’s a significant aspect of normal development as children learn to differentiate between known and unknown individuals, enhancing their emotional growth and attachment behaviors.
