Young friend
In a relationship between a child and a childlover, the child is sometimes called a young friend.
Whilst some reserve the term for the younger friends who are closest to them, ongoing friendship with, and others use it more liberally to describe any child they have contact with. To avoid this ambiguity the variant special young friend is sometimes used to refer to a close friend. Neither term necessarily refers to a sexual relationship.
Many childlovers continue to consider a person their young friend long after they have grown into a adult.
The term "young friend" evolved as a play on the terms boyfriend and girlfriend and is usually abbreviated as yf (or syf for "special young friend") in writing. Online, it has mostly replaced the older terms "boy" and "girl" because many felt the phrases "my boy" and "my girl" sounded more possessive than "my young friend."
