Children experience anxiety as they begin to understand some of the realities of the world, which may be frightening or disappointing. From the point of view of a small child, the feeling of being afraid and out of control is probably a practical definition of anxiety. It is particularly common between the ages of two and six. Young children may have short-lived fears, such as fear of the dark, storms, or animals. Natural developmental fears include fear of being left alone and fear of strangers. Life transitions, such as the start of daycare, being away from home, moving to a new location, and separation from parents or caregivers are stressful events for children.

Children may express stress differently according to age, maturity level and previous experience. Adults should pay attention to the following symptoms and behaviors that children may exhibit due to stress.

Young children react in these ways when the stability and security of their life is violated. Don't confuse this type of regressive behavior with other types of moment-to-moment inappropriate behavior. This behavior is a reaction to stressful events with which the child feels unable to cope. It is a cry for help from a child who is not feeling safe. When he/she is not acting lovable, that’s when he/she feels the least safe.

It is important not to blame or punish these children, who are in particular need of being cared for and protected. Children under stress need help in expressing their feelings and concerns. Their fears need to be addressed because they are certainly real to the child.
