During which period are sexual feelings dormant as children focus on other pursuits, such as school, friendships, hobbies, and sports?

This period is called the "Latency Period".

The period of latency is the fourth stage of psychosexual development in psychoanalytic theory of Sigmund Freud. This occurs from about five years of age until puberty. This period is characterized by a child repressing sexual urges and chooses to associate with other children.
