When Prince Harry and his wife Meghan Markle stepped down as senior members of the royal family and relocated to America, they sought a very different life to the one they had in the UK. Harry and brother Prince William may have many differences of opinion - exacerbated by the Duke of Sussex's tell-all book Spare in which he laid open many family secrets including alleged physical fights between himself and his brother.
However there is one area in which the pair are in agreement - the way in which they are bringing up their kids. Both brothers benefited from their mum Princess Diana's insistence that her royal sons were raised to live as normal a life as possible - and both William and Harry are on the same page when it comes to continuing her legacy with their own children.
Here are the major parallels with how William's three children, Prince George, Princess Charlotte and Prince Louis and Harry's two children, Prince Archie and Princess Lilibet are being brought up…
A 'normal' life away from the media
Prince William and Princess Kate relocated to Adelaide Cottage in Windsor last summer, reportedly seeking a life away from the 'goldfish bowl' of London. This gives their children a chance to roam a little more freely than they could in the city when they resided at Apartment 1A inside Kensington Palace.
Prince Harry and Meghan Markle have made no secret of the fact that they made their US move in order to live a more private life away from the spotlight, not happy with how the British press treated them when they lived in the UK.
A rural upbringing
Both families have a strong connection to nature and the great outdoors, possibly due to William and Harry's many childhood years spent on outdoor pursuits at Balmoral Castle. The Wales family often get stuck into bike riding, sailing, hiking and skiing with their children.
Over in Montecito, the Sussexes' estate is also perfectly positioned for them to embark on many outdoor activities such as hilltop hiking. Their Netflix docuseries also showed other outdoor pastimes like feeding the chickens, playing football and touring their seemingly never-ending gardens.
Quality time with their kids
As working royals, William and Kate have busy work schedules, but they try their best to work their official engagement schedule around school drop-off and pick-up where possible.

HELLO's royal reporter Emily Nash explains: "Whenever possible, William and Kate time their engagements to allow them to take their children to school and put them to bed, even on tours."
Similarly, Harry and Meghan have a focus on spending quality time with their kids. When the Duchess penned an open letter to members of the United States Congress in support of a comprehensive paid leave program for new parents, she revealed their dedication to raising their children.
The Suits actress wrote: "In June, my husband and I welcomed our second child. Like any parents, we were overjoyed. Like many parents, we were overwhelmed. Like fewer parents, we weren't confronted with the harsh reality of either spending those first few critical months with our baby or going back to work.
"We knew we could take her home, and in that vital (and sacred) stage, devote any and everything to our kids and to our family. We knew that by doing so we wouldn't have to make impossible choices about childcare, work, and medical care that so many have to make every single day."
A focus on manners
There is no doubt that the royal cousins will be brought up with the most impeccable manners. We've recently seen Prince William prompt his youngest son Prince Louis to shake hands with staff during a visit to the Royal International Air Tattoo in Fairford.
In Meghan Markle's interview with The Cut, she revealed that manners were also a key parenting focus for them.

Allison joined the family on the school run, and wrote: During the ride, she wrote: "If he [Archie] forgets to say please or thank you, Meghan reminds him of the manners that make the man."
Sweet family time with grandparents
Both the Wales children and the Sussex kids are fortunate enough to have their grandparents around to help. Carole and Michael Middleton live really close to William and Kate, in nearby Berkshire and so they are heavily involved in raising the young royals. It is believed the three children also spend time with King Charles and step-grandmother Queen Camilla.
Meghan Markle's mother Doria Ragland also plays a major part in her grandchildren's life, as was evident in the Netflix show when we saw her join in with lots of family fun. However, given their location, Archie and Lilibet do not get to visit their UK grandparents often.
