While Prince William and Kate Middleton are fearful about the scrutiny all three of their young children will receive as they grow up as royals, they are particularly “nervous” about what their eldest son Prince George will face, as he is destined to be king someday.

“Of course, William and Kate are nervous about what the future holds for George,” a source told US Weekly. “He’s growing up in a different era to his parents. Times have changed since then. There wasn’t social media or internet trolls when William and Kate were children.”

This shift in the world is why William and Kate have chosen to prioritize giving George and his younger siblings, Princess Charlotte and Prince Louis, a private upbringing out of the public eye.

“The Cambridges feel it’s necessary to shield George, Charlotte and Louis from the spotlight and have become cautious about the appearances [they] make,” the insider explained. “Kate and William are being more selective about the events he attends.”

While George is going to be king someday, William and Kate want him “to have a normal life” as a child.

“He’s not called Prince George at school and is simply known as George,” the insider said. “He mixes with children his own age. Kate and William don’t shower him with expensive gifts nor do they over spoil him. Despite his future role, they don’t want him to grow up too quickly.”

“He engages [in] activities similar to any other 8-year-old — playing board games, horse-riding lessons, swimming, baking with his brother and sister, playing football and he can’t wait to start rugby too!” the source continued.

William and Kate “want their kids to be kids, but they’re raising their kids to be well-mannered and not take their status for granted.” For example, George is already interested in philanthropy, and “has been helping William and Kate behind the scenes on some of their projects, especially those involving children.”

“He’ll put ideas forward,” the source said. “You can already tell that he wants to make the world a better place! It’s super sweet!”

George celebrated his eighth birthday earlier this month, and his younger siblings Charlotte and Louis are 6 and 3 respectively.
