While it can't hurt that the four-year-old princess will have a familiar face at her school, the seemingly-bubbly Charlotte should have no trouble making friends.
However, Thomas's Battersea school will discourage Princess Charlotte from having best friends, due to a spirit of inclusion at the private school.
"There's a policy that if your child is having a party, unless every child in the class is invited, you don’t give out the invites in class," said British talk show host Jane Moore (who has friends with children at the school).
"There are signs everywhere saying be kind, that's the ethos of the school. They don’t encourage you to have best friends," she added.

The school costs just under $24,000 a year and accommodates children between ages four and thirteen.
The Good Schools 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."
According toYahoo, Thomas's Battersea boasts impressive alumni such as Cara Delevingne and singer Florence Welch from Florence and The Machine.
Located just five kilometres from Kensington Palace, the school is a perfect fit for the children ofPrince William and Kate Middleton.
"It's a really great little school actually for the reasons I think that it really focuses on kindness, it's a really big thing in that school and the pastoral care is amazing," Moore said.
"It's a school that really expects parental involvement. The parents are very heavily involved in the school so (William and Kate) will be as well."
Princess Charlotte is about to begin her first day of school, joining her older brother Prince George at Thomas's Battersea.

At school, the young royals will be referred to as George and Charlotte Cambridge, due to their parent's royal titles: the Duke and Duchess of Cambridge.
"There won't be any special treatment," Ben Thomas, former headmaster of Thomas’s Battersea, toldPeoplereporters at the time.
"In fact, what his parents would like for him, as any parent would like for their child, is they have a wonderful, fulfilling and private childhood."
