A growing number of researchers are warning about the dangers of watching TV when very young children are nearby. Recent findings suggest that even casual exposure to TV can harm their development and undermine parent-child interactions.
In addition to discouraging screen time for young kids, it warned against watching TV with them nearby, saying the practice hurts their language development. It pointed to several studies, including one from 2008 that found background TV reduced the length of time they played and caused their focus on play to stray. Recent surveys find that about one of three families leave the TV on most of the time.
