your theory, while thinking it obvious, it actualy a part of Erikson's theory of devolpment for young children. (Erikson was a psychologist much like Freud). he had a much different approach to development than others, as his was based more on the functional rather than the theoretical.

during a certain age a child learns trust/mistrust from their parents - usually between infancy and toddler (according to Erikson). much of this comes from the mother's ability to mother. is the child fed and cares for etc. these are the basic building blocks of trust and will form a childs reaction to demands and expectations of people it depends on for survival and coping.

again all according to Erikson.
