Restroom(Toilet training)
Toilet training, or potty training, is the process of training a young child to use the toilet for urination and defecation, though training may start with a smaller toilet bowl-shaped device (often known as a potty). Cultural factors play a large part in what age is deemed appropriate, with the expectation for being potty trained ranging from 12 months for some tribes in Africa[1 ] to 36 months in the modern United States.[2 ]

2 About the anal stage

The anal stage, in Freudian psychology, is the period of human development occurring at about one to three 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.
