Since 2007, when Apple released the first iPhone, a generation of teenagers have grown up with a phone almost constantly in their hand. According to one Facebook executive, millennials look at their phones on average more than 150 times a day.

Mariella Frostrup is joined in the studio by Giles Dilnot from the Office of the Children's Commissioner, child psychotherapist Julie Lynn Evans, social media guru Ben Anderson from the Self Esteem Team, technology evangelist turned tech addiction campaigner Belinda Parmar and Andy Robertson - a journalist specialising in video games and families, to discuss how to parent in the smartphone age.
