The Cambridge children were all at Lambrook School in Berkshire today for a “settling-in afternoon” with their parents. 
This is a new school for Prince George, Princess Charlotte, and Prince Louis. The settling-in afternoon welcomes new students and family members to the school. Classes start tomorrow. Here you see Headmaster Jonathan Perry shaking Princess Charlotte’s hand as the family arrives. 
More about today’s events from The Mirror’s coverage.
“Welcome to Lambrook,” the headmaster told the children. “It’s lovely to have you with us. We’re very excited for the year ahead.”
Shaking them each by the hand in turn, he asked them: “Are you excited?”
All three piped up “yes!”
William said: “We’re looking forward to it”, adding the children had “lots of questions”.
And a video of the family as they arrived at the school.

Many readers will recall that Prince George and Princess Charlotte attended Thomas’s Battersea. Below, Prince George and Princess Charlotte as they arrived for their first day of classes in September 2019.  
And Prince Louis as he was about to leave for his first day at Willcocks Nursery School in April 2019. 
Lambrook is set on more than 50 acres of property near Ascot in Berkshire; students are ages three through thirteen. 
Lambrook notes it is “…keen to encourage our children to develop their interests and explore the things that they are passionate about, whether it be the outdoor environment and its ecosystems, the digital world, the history of cricket, a love for singing, a passion for science or an interest in the world of outer space! Each pupil is unique and our priority is that we recognize and nurture their intrigue, providing time and opportunities to develop their passions.”
Russell Myers of The Mirror reports the school “has its own orchard, 9-hole golf course, 25-meter swimming pool, and a cricket pitch.” The school uniforms include basics in blue and navy. 
Here you get a good look at the dress worn by girls. 
The school’s uniforms are available online through Billings and Edmonds and at the retailer’s store in Eton. 
Prince Louis appeared to be wearing the nursery uniform with its short sleeve blue/green tattersall check shirt and navy Bermuda shorts. It looked like Princess Charlotte was in the Lambrook Summer Dress in navy gingham with belt, and Prince George sported the school’s short sleeve blue and green check shirt with navy Bermuda shorts.
Here is one more look at the Cambridge children today. I can’t get over how tall Prince George is already! 
It’s really sad when you realize that their great-grandma died the next day. I barely even knew either of the great-grandparents who were alive when I was born. Louis is the same age I was when my great-grandpa died.
