While the psychological world that the newborn confronts is complicated they possess a biological predisposition to create a sense of who they are or, as psychologists term it, a "sense of self" from the social experiences they encounter. Beginning in their second year a profound continuing struggle exists between infant and caretaker as the child battles to establish their autonomy apart from the people who controls their destiny. But because babies are not born with instructions and parents have their own childhood-based limitations, the "good-enough" parent-child interaction needed by a child is not always gained, to the long-term suffering of both. Which is where psychotherapy may enter their lives but that is another matter.
