James Middleton has revealed that his son Inigo is using hand-me-downs from his sister Kate Middleton's three children Prince George, Princess Charlotte and Prince Louis –exclusive interview

Princess Kate and Prince William are parents to George, 11, Charlotte, 9, and Louis, 6, while Pippa and her husband James Matthews share son Arthur, 5, and daughters Grace, 3, and Rose, 2. James wrote that while the outfits seemed "enormous" for the baby, he didn't realize that Inigo would quickly grow and "fit them in a blink."

Kate Middleton may be a member of the British Royal Family, but she remains extremely close with her own clan. Case in point: the Princess of Wales shares her children's old clothes with brother James Middleton 's baby son, Inigo.

James Middleton says his big sister gave his son Inigo “suitcases” full of gently worn royal duds from her own kids.

Carole and Michael Middleton “saw it as a challenge” because they wondered “where they had gone wrong,” he says

James Middleton has praised Princess Kate for giving him a platform to speak about mental health as he cannot "ever avoid or hide away" from who his sister is. In his latest book, the 37-year-old explained that he first confided in his family - including Kate - about his struggles in 2017.
