A Little is a person who plays the role of a much younger person, sometimes, but not always, a version of themself, in a consensual age play relationship or scene.
Incorporating child-like attitude and behavior, a little will often identify as a specific age—anything ranging from infant to teen (also referred to as “middles”). Some littles adopt physical mannerisms and activities of children, including changing their voices, playing with toys and dolls, and wearing clothes in the style of the age they’re portraying.
Anyone of any age can be a little and the role is not limited to gender or sexuality. The complementary role in an age play relationship is a Big, someone who plays the Daddy, Mommy, or Caregiver, depending on the “relationship” to their little.
