Screen use among toddlers and preschool children.

It is common to see young children playing with a mobile phone or a tablet. However, the decision about the availability of an electronic device and how and when to use it depends on adults. The concern is the increase of such practice at the expense of activities and social interaction by talking and being in contact with others, as well as other aspects of children's health (overweight and sleep disturbances). It is yet unclear how the generalized use of screens affects development. The physical and psychological mechanisms of such effects are also unknown. The purpose of this article is to provide a current view of the effect of early exposure to screens on the comprehensive development of children and parents' perceptions. It would be conducive to implement education projects for parents and legal guardians that promote an adequate child stimulation at home.
