The presence and variety of mobile devices in Spanish homes, regardless of the social and economic con-text, has been widespread for years. Several studies focus on parental mediation in children's consumption of smart devices, however, there is a lack of scientific evidence about how the educational level and the professional profile of parents affect children's digital media consumption. This study analyzes the influence of the socio-educational level of families on the consumption of digital screens. The study deepens the understanding on the educational level of parents, as well as their professional category. A quantitative methodology was applied on a sample of 792 primary school children, between 5 and 9 years of age, in three Spanish cities. The consumption of television, smartphones, tablets, computers and videogames was analyzed. Results indicate that, the lower the level of education and professional category of the mother, the greater the consumption of content through smart devices by children. The study demonstrates, therefore, the importance of considering the educational and professional levels of mothers and fathers for a better understanding of the consumption of digital screens and, at the same time, as an opportunity for designing family strategies that encourage critical thinking and digital media education.
