Despite the alleged rift between the Sussexes and Cambridges, Prince Harry is said to be closed to his sister-in-law, Kate Middleton, and nephew, Prince George. Meghan Markle's husband treated the wife of his brother, Prince William, like a long-lost sister, while he had a heartwarming reaction upon meeting his eldest nephew.
In Angela Levin's 2018 biography, Harry: Conversations with the Prince, the author revealed that Prince Harry was happy upon the birth of his first nephew in 2013, via Express. At the time, the Duke of Sussex was only 28 years old, but often talking about the new addition to their family even if he was at the photographic exhibition in London, documenting the work of Sentebale, which is one of his charities.
Prince Harry said that he had to cuddle the little prince, who was crying his eyes out when he met him. However, he hoped his Prince William knew how expensive his babysitting charges were at the time.
As an uncle, Prince Harry said that he would make sure Prince George would have a good upbringing, would be happy, keep him out of danger, and the rest would be up to his parents. Prince Charles and Princess Diana's youngest son was heavily regarded as a "fun uncle" due to his mischief reputation.
However, this changed when Michelle and Barack Obama visited the royal family in 2016. In an interview at the Invictus Games launch, the former First Lady said that the most precious thing upon their visit was seeing Prince Harry and Prince George.
Prince George kept on asking Prince Harry why he was so quiet, as he was trying to be on his best behavior when the Obamas visited. The young prince thought something was wrong with his uncle because he would normally throw the child around the room when no one was around.
Meanwhile, aside from Prince George, Prince Harry was also close to Kate Middleton. The two used to be very close as they spent a lot of time together before he got married to Meghan Markle in 2018.
Prince Harry and Prince William formed a "tight-knit" bond after the death of their mother in 1997. The two brothers, along with Kate Middleton, started to work together when Kate and William got married in 2011.
The Duchess of Cambridge joined their charity, The Royal Foundation. They also spearheaded the Heads Together initiative to spread awareness about mental health. Hence, Prince Harry started to see Kate Middleton as his big sister.
No one filled the hole that Prince Diana left after the tragic accident that claimed her life. Prince Harry looked for someone to lean on, and Kate Middleton helped to fill that gap. When she got engaged to Prince William, Harry called her as the big sister "he never had."
