(NewsNation) — Prince William has revealed how he and Kate Middleton spoke to their three children about her cancer diagnosis.

In an interview with Brazilian television host Luciano Huck, William, 43, spoke openly about how the past two years have been “very tough” amid the dual cancer diagnoses of Kate, 43, and King Charles, 76.

The Prince of Wales told Huck that keeping things from Prince George, Princess Charlotte and Prince Louis isn't something that works, and he and Kate "chose to communicate a lot more with our children,” according to People magazine.

"Now, that has its good things and its bad things. Sometimes you feel you're oversharing with the children you probably shouldn’t," William said. "But most of the time, hiding stuff from them doesn’t work."
