Today, the media is a very widespread means of communication who is easily accessible to children, and the aim of this work is to explore how animated films affect preschool children. In preschool age, children acquire knowledge best and most by observing their environment and the actions of other people (most often close people). Very often, children find substitutes for close people in animated films and their favorite characters. Preschool children are increasingly exposed to the influence of the media and animated films. Animated films have positive and negative effects on children's behavior. More and more subliminal messages appear in animated films, which also have an impact on children's behavior. It is essential that parents and kindergarten teachers give their children selected animated films that have a positive impact on development and behavior and that they talk with children about what they have seen. Animated cartoons are an essential item in a child's life and development. We must not forbid children from watching animated films, but we should direct them to adequately understand what they are watching and draw positive lessons.
