The 'critical detail' that helped Prince William and Kate Middleton make this huge decision for their children

Kate Middleton and Prince William are set to send their three children to Lambrook School when they move to Windsor for a very specific reason, according to a royal commentator.

•  Rachie Bowie and Roberta Fiorito, hosts of podcast Royally Obsessed, claim that the Cambridges chose Lambrook because of some 'critical' details. 
• The Cambridge children will start at the prep school in September, reportedly costing Kate and William around £53,628 annually for Prince George, Princess Charlotte and Prince Louis. 
• In other royal news, Lady Louise Windsor is set to to face 'intimidating' tradition at St Andrew's university.

Speaking about Kate and William's decision to send their children to Lambrook school, Roberta Fiorito said, "There's a lot of conversation about why the Cambridges chose Lambrook. When they could have chosen Ludgrove, or St Andrew's at Pangbourne, which is where Kate went to."

She added, "Lambrook is known for these values, which are kindness, courtesy, curiosity and creativity."

The royal expert added that this is a school that allows all three kids to be in the same place", which she describes as a "critical detail".

"It gives them that orbit that is very close to home and I can imagine that was a really key detail," she concluded.

Lambrook School - a co-educational Prep School for 615 boys and girls aged 3-13 - is set in 52 acres of countryside, has its very own Orchard complete with bees, chickens, and even pigs. 

There is also woodland for the little ones to explore, a nine-hole golf course, a 25-metre swimming pool, a cricket pitch, squash courts and a dance studio.

Prince George and Princess Charlotte have previously attended Thomas's Battersea in London, with the family expected to be relieved that they no longer have to take on the 'nightmare' school run.

It's also been reported that Prince William will be taking on a key role when his children start at their new school next month.

The proud dad will be taking on the morning school run, taking on the 14-mile round trip every day with his three children, when he isn't off on royal duties.

Kate and William will be relocating their family to Adelaide Cottage - a property that will be much closer to the Queen than their apartment in Kensington Palace. But although the move will be a big change for the children, especially with starting a new school, they will be much closer to their family. 

The Queen spends a great deal of time at her Windsor home, and Kate Middleton's parents live in Bucklebury in Berkshire, which means the children will be able to see their grandparents and royal great-grandmother whenever they please.
