Why does a psychologist need a child who has survived a traumatic experience?
In psychology, there is a concept of containment: when a child cannot cope with his emotions, his parents help him to live them. To calm, listen and explain feelings - parents use their emotional resource as a "container" for the child's emotions.
During the war, parents cannot accept the experiences and pain of their children to the same extent, because they are also overwhelmed with pain and suffering. When a mother worries, and cries, she becomes an unreliable object of attachment for the child.
