Princess Charlotte arrived on her first day of school at Thomas's Battersea with parents Prince William and Kate Middleton.

The second child of the Duke and Duchess of Cambridge is joining her older brother Prince George who has been attending the school for two years already.

Thomas's Battersea is a private preparatory school near Kensington Palace that houses hundreds of students. 

In a clip shared by Kensington Palace on Twitter, Princess Charlotte could be seen shaking the school official’s hand bashfully and ruffling her hair ponytail after.

Prince William held George’s hands and Middleton held Charlotte’s as both kids walk to the school in their complete dark-colored school attire.

Despite her royal lineage, the princess will not be addressed as “Her Royal Highness Princess Charlotte” in school but, instead, will be called “Charlotte” by her teachers and classmates. She follows her older brother who has been simply known as “George Cambridge” in the school.

Close friends of the princess might also call her Lottie if she permits after Middleton revealed the sweet nickname, People reported.

Back in the school days of Prince William and Prince Harry, the two were known as “William Wales” and “Harry Wales” in line with Prince Charles’s title as the Prince of Wales.

While going to a big school for the first time might intimidate kids, Princess Charlotte was simply excited to join her brother.

 “She can’t wait to be with George at big school. She is so excited about it all,” a royal source told People.

In the past events, Princess Charlotte has exhibited her outgoing and friendly character in many instances such as waving to crowds and adorably greeting officials during royal tours.

 “Charlotte has got a real character, she is very excited about starting school,” another insider told Vanity Fair.

The school curriculum waiting for Prince George and Princess Charlotte is no piece of cake.

Their holistic curriculum for Prince George’s Year 2 includes core subjects English, math, science, geography and history but also includes the following subjects: art, ballet, drama, French, music, P.E. and I.C.T.

“The curriculum presented in Year 2 reflects the increased ability of the children, both academically and socially,” Head of Lower School Helen Haslem said on the website via People.

“It sees the completion of the basic skills in literacy and numeracy in Key Stage 1. Individual strengths and talents begin to emerge, which you will undoubtedly begin to see.”
