In infancy, around what age does separation anxiety begin?

• A. 3 months
• B. 6 months
• C. 9 months
• D. 12 months

Answer: (C)

Separation anxiety emerges when a child has formed a strong attachment and understands that a caregiver continues to exist even when out of sight. By about nine months, infants commonly start showing distress when a caregiver leaves, cling to the parent, or become upset with unfamiliar people. This reflects the child recognizing that the caregiver’s absence is temporary and that they will return. Earlier ages, like three months, are typically too early for these clear signs, and around six months some beginnings may appear but are less reliably observed. By around twelve months, the pattern is well established and can continue as the child approaches toddlerhood.
