Separation anxiety is normal in very young children (those between 8 and 14 months old).
Kids often go through a phase when they are “clingy” and afraid of unfamiliar people and places.
When this fear occurs in a child over age 6 years, is excessive, and lasts longer than four weeks, the child may have separation anxiety disorder.
Some children also develop physical symptoms, such as headaches or stomach aches, at the thought of being separated.
The fear of separation causes great distress to the child and may interfere with the child’s normal activities, such as going to school or playing with other children. [2]
