Kensington Palace also announced that Meghan and Harry will attend an awards night for Well Child on September 4, a charity which works on behalf of seriously ill children and their families and caretakers. The awards celebrate the inspiring qualities of the young people and the dedication of those who 'go the extra mile to keep children healthy and happy, including the outstanding health, social care and education professional.'
