Objective: We aimed to evaluate the proportion of parents who report having discussed the subject of their child's exposure to screens during a consultation with a health professional. We also aimed to assess preschool exposure to television and mobile media devices, and to explore parents' views on the benefits and risks of exposing their children under 3 years old.
