London, UK - Britain's Prince William on Friday said his wife Catherine, popularly known as Kate, was "edging herself back into doing more" overseas trips following her cancer diagnosis in 2024.

William (43) told Heart radio's breakfast show that the Princess of Wales was "buzzing" after her visit to Italy earlier this month, her first foreign visit since the diagnosis.

"She's been through so much in the last couple of years, particularly, and she'd been looking forward to the Italian trip a lot, and so I'm really glad it went really well."

Kate (44) announced she was in remission from cancer in January 2025 and has gradually returned to public duties since then.

"She's an amazing mom, an amazing wife, and literally our family couldn't cope without her," William told the radio show, speaking from the Isles of Scilly off the Cornish coast in southwest England.

The father-of-three spoke about parenting as well, including the school run for his children, which he said "can be" chaotic.

"Charlotte, Louis, if you're listening, make sure you're on time, please make sure [you're] not fighting over who's listening to what this morning," William said, addressing his two youngest children.

His eldest son, George (12), was "boarding" on Thursday night, William said.

The heir to the throne revealed that jam sandwiches were kept in the car for the youngest Louis (8) to snack on.

"He'll leave jam fingerprints throughout the car, which is really helpful," said William.

William has been giving more personal interviews recently, and last year revealed that he and Catherine have a phone ban to protect their children.

The prince, who admitted he is "definitely not a morning person", said his breakfast of choice is "eggs on sourdough".

He said he enjoyed "motivational" music and "loved dance music."
