The spread of digital technologies in everyday life is increasingly affecting even childhood, changing the environment of development with an increase in virtual experiences. Epigenetic studies and Pnei legitimize concerns about a possible negative impact on the psychobiological development of the Self. The authors identify some critical characteristics in the use of video games, social networks and other platforms, with the potential to alter the natural process of development. The effects seem to affect mainly psychomotor skills, attention processes, and relational skills. The urgent need for rules of use is emphasized to avoid imbalances in children’s life experiences, which would affect the organization of the Self, influencing later adult life, reducing the ability to sustain allostatic loads and with the possibility of transgenerational transmissions. The assumption of norms calls on the adult figures to function as an auxiliary Self, constant but flexible, throughout the developmental age.
