Jedi youngling

Youngling" was a term for any child of any species. Force-sensitive younglings who were taken to the Jedi Temple to be trained as Jedi were known as Jedi younglings.

Children needed adult supervision, as they could not take care of themselves on their own. When Din Djarin left the Child aboard the Razor Crest all by himself, Peli Motto admonished the Mandalorian, saying that he couldn't leave a child alone like that and that he had a lot to learn about raising a young one.

As a child, Ben Solo coined a new name for himself but later dismissed it as "stupid." Snoke encouraged Solo to discard his old identity by taking the name that he invented during his childhood. He believed that children did not practice self-deception; therefore, they had only pure thoughts and were true to their nature.
