An insider RadarOnline.com that Harry sees Christmas as the perfect opportunity to once again bring Markle and their children – Prince Archie, 7, and Princess Lilibet, 5 – to the U.K. The source shared: "He always gets very homesick at that time of year. He misses being a part of all their traditions, and he would love Archie and Lilibet to experience a proper royal Christmas." According to the source, Harry knows his brother will react badly to the idea – but Harry "simply doesn't care" what William thinks. "If he wants to be nasty about it and turn it into some sort of ugly confrontation, Harry can't stop him, but he's not going to let William dictate the terms of when his children spend time with their grandfather," the insider added.
