"Preteen" is a term that refers to a boy or girl who is less than 13 years old. A preteen is sometimes called a preteenager.
The term "preteen" is typically used to describe a boy or girl who is 11 or 12. The first known use of the term was in 1952. During preteen years, kids tend to become more independent and try to expand their limits. It is important for parents of preteens to help their children understand their boundaries and unacceptable behavior. At the same time, parents should encourage preteens to accomplish great things in their lives and show pride in their kids' accomplishments.
