When does separation anxiety typically peak in infants?

Separation anxiety typically peaks in infants between 10 to 18 months of age. During this developmental stage, children become more aware of their surroundings and form strong attachments to their primary caregivers. As they begin to understand the concept of permanence—realizing that their caregivers exist even when they are not present—they may experience increased anxiety when separated from them. This is a normal part of their emotional growth and indicates that they are developing secure attachments.

At this age, children may exhibit distress when a parent leaves the room, and they can become highly dependent on their caregivers for comfort and security. Understanding this peak period can help caregivers and healthcare providers support children as they navigate these feelings, offering strategies to help ease the transition during separations. Recognizing that separation anxiety is a common phase supports parents in managing their child's emotional needs during this time.
