Supernanny star Jo Frost has made a public plea to the U.K. government to raise the minimum age for social media use to 16. "This is a message to [Sir Keir Starmer, the Prime Minister of the U.K.]," Frost, 55, said in an Instagram video on Tuesday, April 14. "You are a father, a father of two children, so you know what it is to protect them, to look at them and to understand what they are ready for and what they are not." Frost continued, "I'm speaking to you now as a British citizen and as someone who has spent nearly four decades inside family homes, guiding them and educating them.
