Sesame Street is included as an example of suitable viewing for small children
The American Academy of Paediatrics AAP has announced new screen time guidelines for children aged up to two.
It had recommended that children have no screen time before the age of two.
But it now says children aged over 18 months can use video chat with family, and 18-month to five-year-olds can watch "high quality" programmes with parents.
It named programmes such as Sesame Street as examples of appropriate TV shows.
"Families should proactively think about their children's media use and talk with children about it, because too much media use can mean that children don't have enough time during the day to play, study, talk, or sleep," said Jenny Radesky, the lead author of the AAP report Media and Young Minds.
