A Child under five constantly in public with Jam on his or her face. Jamtart's are often slathered with jam as they are temperamental children and Mom is too tired to fight the child by washing the face area, parent gives up the 'pressure' of presenting child in public.
Sally never knew that washing a child's face could be such an ordeal, instead to ease her mental pain, she let him run free around town as a Jamtart Baby.
