Stranger anxiety
Stranger anxiety is a form of distress that children experience when exposed to people unfamiliar to them. Symptoms may include: getting quiet and staring at the stranger, verbally protesting by cries or other vocalizations, and hiding behind a parent. Stranger anxiety is a typical part of the developmental sequence that most children experience. It can occur even if the child is with a caregiver or another person they trust. It peaks from 6 to 12 months but may recur afterwards until the age of 24 months. As a child gets older, stranger anxiety can be a problem as they begin to socialize. Children may become hesitant to play with unfamiliar children. Children develop such strong bonds to their primary caregivers, that they are likely to feel uneasy around someone who has an unfamiliar face. Foster children are especially at risk, particularly if they experienced neglect early in their life.
