It's a big moment for Prince George, who arrived at Thomas' Battersea for his first day of primary school Thursday morning.
Dressed in a navy V-neck pullover, matching Bermuda-style school shorts, and black shoes, there were a few signs of first-day nerves from the hesitant four-year-old.
Although it's safe to say he's mastered the handshake...
The Prince was accompanied by his father on the school run, but the Duchess of Cambridge, who is pregnant with her third child, was not well enough to join her son.
A spokesperson from Kensington Palace said: "Unfortunately, the Duchess of Cambridge remains unwell, and will not be able to accompany Prince George on his first day of school. The Duke of Cambridge will drop off Prince George this morning as planned."
Prince William and George were welcomed by the Head of Lower School, Helen Haslem, who escorted the new pupil to the reception classroom where he'll start his full-time education.
The independent school, where fees cost from £17,604 a year, was recently reviewed by The Good School's Guide as: "A big, busy, slightly chaotic school for cosmopolitan parents who want their children to have the best English education money can buy. That is what they want and, to a large degree, that is what they get."
However, the guide also added there were "plenty of opportunities for pupils to excel but withdrawn types might find it all somewhat overwhelming."
The school has 543 pupils aged four to 13, and according to the guide, it has "all the facilities for a broad curriculum." It is said to have "great science labs," a new music center, two art studios, lots of sports and "outstanding" drama classes with "huge productions by each year group being put on over the year." Who's betting young George will be the star of the show?
George's first day at school marks a fresh new start for the Cambridge family, who are settling full-time in Kensington Palace.
William will be supporting the Queen by carrying out a full program of engagements throughout the autumn in his new role as a full-time royal. And Kate will, no doubt, be helping George settle into school and preparing Princess Charlotte for nursery, as well as continuing with her charity work.
