The libido now becomes focused on the anus and the child derives great pleasure from defecating. The child (from 1 to 3 years) is now fully aware that they are a person in their own right and that their wishes can bring them into conflict with the demands of the outside world (i.e. their ego has developed). Freud believed that this type of conflict tends to come to a head in potty training, in which adults impose restrictions on when and where the child can defecate. The nature of this first conflict with authority can determine the child's future relationship with all forms of authority.Early or harsh potty training can lead to the child becoming an anal-retentive personality who hates mess, is obsessively tidy, punctual and respectful of authority. They can be stubborn and tight-fisted with their cash and possessions.
