On Max's block building - The Phallic stage or maybe I'm reading too much into this...

The Oedipus complex is an important concept in Psychoanalysis and Freud believed that this case study of Little Hans supports this idea. Freud believed that children pass through five stages of development, known as the psychosexual stages because of Freud's emphasis on sexuality as the basic drive in development. These stages are: the oral stage, the anal stage, the phallic stage, the latency period and finally the genital stage. It is the first three stages which take place in the first five years of life of a child.
