At what age do the first signs of separation anxiety typically appear?

The first signs of separation anxiety generally begin to emerge around six to eight months of age, as infants develop a stronger attachment to their primary caregivers and start to understand the concept of object permanence—recognizing that people and objects continue to exist even when they are not present. Therefore, it can be said that the age of five months, while not the most common onset period for separation anxiety, falls into the timeline of infancy when infants are starting to form attachments.

The onset of true separation anxiety is often more noticeable at around six to eight months when children become more mobile and aware of their surroundings. This developmental stage typically coincides with the child’s growing cognitive abilities, leading to increased distress when the caregiver leaves the room. Understanding this timing helps caregivers provide appropriate support and reassurance to children as they navigate their emotional development.
