Lerner, C.; Barr, R. (2014) Screen Sense: Setting the Record Straight. Research-Based Guidelines for Screen Use for Children Under 3 Years Old Zero to Three: Washington, D.C.
This resource—developed in partnership with leading researchers in the field of media and young children — describes what is known about the effect of screen media on young
children’s learning and development. Rich, interactive experiences between parent and child are the most beneficial for babies and toddlers. The report warns that many of the the "2-D" experiences provided by TV, tablets, and smartphones don't provide the kind of social interaction and real-world learning that proves especially beneficial to infants and toddlers — unless parents are engaged in that activity.
