Today's children are born and raised in media-saturated environments, surrounded by televisions, computers, tablets, smartphones, and other portable electronic devices. Because these devices have become an indispensable part of everyday life, they have a significant influence on children's entertainment and leisure, as well as their education. This study, therefore, examined the media environment in young children's homes (from 0 to 6 years of age), how early and how much they use television, computers, and tablet/smartphones, and the media environment in their homes and the parents' rules and regulations for their children's electronic media use. The sample for this study consisted of 412 parents of 0- to 6-year-old children who brought their children to the Social Paediatrics Department of the Faculty of Medicine in Ankara, Turkey, for developmental check-ups. The data for this study were collected through a questionnaire that was prepared by the researcher. The findings indicate that almost all children live in homes with different types of electronic media devices and they start to use them at an early age with longer time than recommended and parents try to use some rules in order to regulate their children's usage.
