The study focused on a jewish boy from Vienna, Austria known as Little Hans who, at the age of 3, had developed an interest in his "widdler". Naturally, his mother was concerned and threatened that the doctor would cut it off if he didn't stop touching it.
Around the same time, Hans' mother gave birth to a baby girl, Hanna. Initially, Hans was jealous of her for taking all his mother's attention but this wore off in a few months
Hans had a considerable interest in other children, especially girls and formed emotional attachment with them. When he was around 4, a phobia of horses developed - it was discovered that he had witnessed a horse falling over and it was "possible" that Hans thought of his father when this happened

Freud realised that Hans had developed the phobia shortly after he had anxiety dreams about losing his mother and this was also the time he was warned about playing with his "widler" - he had a repressed longing for her. His father told him If you don’t put your hand to your widdler any more, this nonsense of yours’ll soon get better

He spoke a lot about this as well as the colour of his mother's underwear and loving going to the toilet with the maid or his mum. Hans also had an imagery friend, "Lodi" after saffalodi meaning German sausage. His phobia began to decrease and he had two fantasies
