Kate Middleton is said to have had such a great influence on her husband, Prince William, that she treated him “like the fourth child.”
The claim was proposed by royal writer Tom Quinn, who wrote a new book, “Yes Lady: The Secret Life of Royal servants.” Quinn spoke with hundreds of former and current palace staff to learn what it feels like to watch Windsor House.

“Sometimes, if you don’t do things the way he wants to do, William will lose his temper and excitement [as heir to the British throne],” Quinn claims to be a Fox News digital number.
“But Kate is very good at managing, just like she manages her tantrums of three children, Prince George, Princess Charlotte and Prince Louis.

A former employee claimed: “‘They both were quick to get angry’, adding that the king and his heirs were used to doing things for them, making them “very picky.”
“Everything that you do for them from childhood is often spoiled and susceptible to irritation because they don’t know how much work they involve in washing and ironing, ironing, polishing and sewing when they have never done anything themselves.”

“In many ways, William has an emotionally destructive childhood,” Quinn explained to Fox News Digital. “I’m not just about it,” he said. His mother, Princess Dianawhen he died at the age of 15, this itself is huge. Everyone can understand that it is very harmful to him.
“But before that, the division between his parents was very public. All the unpleasantness between his parents played a role on the world stage. At the same time, he was cared for by paid employees.”

“For the most part, it created an adult in William, and he really needed it,” Quinn claimed. “He loved spending time with Kate’s family because unlike him, they were very warm, very close to each other, and very emotionally aware.

“When Kate and William first got together, William tended to lose his temper, if things didn’t go because he was still the emotionally needed kid, growing up, adult.”
As far as Kate is concerned, they are “not that right now” for those who are allegedly tantrums.

William reportedly witnessed the importance of being a personal parent through Princess William.
According to Quinn’s book, Kate “vowed to remove many of the work (if not all) related to nursery.” She hopes her child has a close connection with her parents despite the royal title, not the paid caregiver.

“Although many old guards of the Palace don’t approve, she spent many royal insiders considering the shocking time, which is engaged in normal parenting tasks that have been paid to paid employees in the past,” Quinn wrote. “But Kate also acknowledged If you join the royal family, You have to follow some (even if not most rules).

“A very entrenched tradition that Kate doesn’t like is the common rule that you don’t care for your own children,” Quinn explained to Fox News Digital. “From the earliest babies and toddlers, others, usually nannies and nursery maids, do all the work for the children. Royal children have traditionally not connected with their parents.
“Once the boys reach a certain age, they’re sent to school,” Quinn continued. “But as babies, they connect with someone who pays and leaves. Then, another person comes. It’s a very harmful tradition, and Kate sees it from the beginning. Kate said, Kate said, ‘I won’t do that.’ She was able to do it because she got William’s support.”

But as expected, Kate did have to learn some important rules about royal etiquette earlier in William.
“At Kate realized that as a senior royal, you had to dress with caution…she once bought clothes that William thought were not suitable,” one of the prince’s advisers claimed to be Quinn, as quoted in the book.

Former Kensington Palace also claimed Quinn: “Kate was always happy to accept advice from lower staff, with courtiers who got along better with her.
Quinn also claims in his book that despite all the royal classes, the Princess of Wales did not allow her three little kids to attend “Blood”. The long-term ceremony calls on royals to apply blood to the face of the first murder during a fox or buck hunt.

“Catherine, the princess of Wales, let go and insisted that her children would not have blood,” Quinn wrote. “The king himself went through the ceremony as a child, as did his two sons, William and Prince Harry.”

Quinn claimed to the Fox News numbers: “Kate certainly said that this wouldn’t happen to her kids.” “I think Kate was shocked because that could happen to the kids.”
Kate is not the only royal wife who opposes the ancient traditions involving the royal family.

“King Charles worshiped stalking when he was young and loved hunting (i.e., fox hunting),” Quinn wrote. “When Diana, who is actually always more comfortable in the city, said she hates shooting, fishing, stalking and hunting – all the major states pursued the Royals were loved by the Royals, and he was shocked.
