Prince William gives rare insight into sleeping arrangements with Kate Middleton in surprise confession

Prince William has revealed a super rare insight into his sleeping arrangements with Kate Middleton in a surprise bedroom confession.

Now, the Prince and Princess of Wales have been married for 13 years, celebrating their anniversary back in April, and currently reside at Adelaide Cottage near Windsor Castle alongside their three children, Prince George, 11, Princess Charlotte, nine, and Prince Louis, six,

While the pair are fairly private regarding their personal lives, William has reportedly opened up a little more about how he and Kate 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.

As well as potentially even heightening your immunity, cuddling up with your dog can help reduce blood pressure and heart rate.

However, there are some cons to dozing off with your doggo as Sleep Medicine Physician Dr Dustin Cotliar warns: "It may be tempting to snuggle up with your dog at night, but sleeping in bed can definitely disturb one’s sleep.

"They might move around during the night, disturb your body’s ability to regulate its temperature or exacerbate allergies."

And it's not just nighttime disturbances and allergy concerns as the Sleep Foundation also points out issues of germ exposure and territorial behaviour.

"It’s often best to get your dog used to sleeping in a bed next to you in your bedroom," Dr Cotliar adds.
