Gender non-conforming children are children who do not behave or present in ways that are typical for their assigned gender. A gender non-conforming child may prefer to dress in clothes deemed appropriate for the opposite sex, surround themselves with opposite sex playmates, and shun toys typical of children of their gender. They may also state that they are or wish to be the opposite sex.
The term "gender non-conforming" can be used to encompass other terms such as transgender, transsexual, and genderqueer.
