The Duke and Duchess of Sussex have encountered numerous hurdles as a couple - but last week it was clear they’re set to face their toughest challenge yet: the future safety and wellbeing of their children. Prince Harry and Meghan gave insight into their concerns as they marked World Mental Health Day during a visit to New York – their first time in the city since their “near catastrophic car chase” back in May.Taking to the stage alongside her husband at the Archewell Foundation Parents’ Summit: Mental Wellness in the Digital Age, Meghan looked close to tears as she passionately told the audience how she’s “frightened” about the potential consequences of Prince Archie, four, and Princess Lilibet, two, using social media as they grow up.
