1. Development of trust versus mistrust – (0 to 18 months):

The first developmental stage in Erikson’s theory occurs during birth to until child is 18 months old (in some articles says it is between birth to one year old (Cavanaugh & kail, 2010)). During this stage of development the basic strength of a child is hope. The child has full hope that, he or she will get anything the whenever they wants. The main interaction of a child during this stage is with his or her mother and family members. Through these interactions the child learns both trust and mistrust but should be in right proportion (Fleming, 2004). According to Passer & Smith (2007), this phase is depends on how well the needs are met and how much love and attention are receiving and develop a basic trust and mistrust of the World.
