The id is the combination of pleasure-seeking desires and we are born with it. The ego develops later and controls the desires of the id. The superego is the moralistic part of the personality that develops when a child interacts with significant others such as his parents. The Superego can be seen as the conscience. It is the ego's job to maintain a balance between the id and the superego. Freud believed that children go through five stages of development, known as psychosexual stages because of Freud's emphasis on sexuality as a fundamental drive in development. These phases are: the oral phase, the anal phase, the phallic phase, the latency period and finally the genital phase. The phallic stage, from three to five years of age, was the stage in which the child's sexual identification was established. During this phase Freud hypothesized that a boy would experience what he called the Oedipus complex. This would provide the child with highly disturbing conflicts, which had to be resolved by identifying with people of the same sex.
