Prince William reveals one ‘really tough’ question Prince George, Princess Charlotte and Louis ask him all the time

Prince William has revealed the one 'really tough' question his three young children ask him all the time.

Fans of the royals are always keen to hear what it's really like for the Prince and Princess of Wales when it comes to their family life, namely what it's like raising the likes of Prince George, 11, Princess Charlotte, nine, and Prince Louis, six,

Now, as many parents will know, children are inquisitive little beings who seem to love nothing more than constantly asking you questions and, for William, his brood are no different.

The father-of-three chatted with Aussie TV star, Robert Irwin, in Cape Town last week (5 November) with William over in South Africa for the fourth annual Earthshot Prize Awards ceremony. William founded the prize a few years back in 2020 and Irwin supports as a global ambassador.

During the chat, Irwin asked: "I have to ask — we’re in South Africa, one of the most amazing countries and continents for wildlife - do you have a favourite African animal?"

William responded: "It’s a really tough question.

"My children ask me this regularly. I think I’m going to have to say the cheetah."

Agreeing his choice was 'very cool', Irwin revealed: "It's chameleons for me. The unsung hero. I love 'em."

While Will and Kate, are fairly private regarding their personal lives, the former has reportedly opened up a little more about how he and his wife tend to sleep together.

It comes after William reportedly stopped to pet a wellwisher's dog during a visit to Duchy College in Cornwall.

Louise Harland told Hits Radio Cornwall that the 42-year-old stroked her dog, Jacks, and revealed to her that his family dog, a cocker spaniel named Orla, often sleeps on the bed alongside him and Kate.

"[William] said that his little dog sleeps on the bed with them at night, with him and Kate," Louise claimed.

"[He was] absolutely in love with my little dog. He asked what breed he was and he's never met one of those breeds, he's a Cockerjack, so he's a little bit of a unique combination."

According to the Sleep Foundation, sleeping with a pet can provide a variety of benefits, including comfort and security as service dogs can provide emotional support to people with post-traumatic stress disorder (PTSD) when they experience a nightmare.

Such dogs are trained to identify physical signs that indicate a person is having a nightmare, so they can disrupt the nightmare by waking their owner up.

Sleeping with your dog is also said to help ease symptoms of mental health conditions, help regulate emotions and reduce anxiety and loneliness.
