Parents regularly use media to help regulate their childs difficult emotions, particularly for those with a more difficult temperament. However, no research has examined how this may be related to the development of problematic (or addictive-like) media use in early childhood. The purpose of the study was to examine associations between temperament, parental media emotion regulation, and problematic media use in young children, using both questionnaires and observational data. Participants included 269 toddlers (2-3 years old) and their parents, who completed several observational tasks and questionnaires. Analyses revealed that higher levels of media emotion regulation was associated with more problematic media use and more extreme emotions when media was removed in toddlers. Additionally, temperament (specifically negative affect and surgency) was related to problematic media and extreme emotions and was mediated by media emotion regulation. Parents should avoid using media as a primary way of regulating their childrens emotions as this may be related to the development of problematic media strategies during infancy.
