The anal stage, in Freudian psychology, is the period of human development occurring at about one to two years of age. Around this age, the child begins to toilet train, which brings about the child's fascination in the erogenous zone of the anus. The anal stage coincides with the start of the child’s ability to control their anal sphincter, and therefore their ability to give or withhold gifts at will.
