Charlotte gave a small wave to the cameras as William told Haslem: “First day, very excited.”
Kate, who was still sporting a summer tan, added: “How are you? Did you have a nice summer?”
The royal parents then took Charlotte to her classroom of 21 students to meet her new teacher and settle in. The young royal will be known as Charlotte Cambridge in school, just as her big brother is known as George Cambridge.
Kate and William are navigating a path that allows their three children — Prince George, Princess Charlotte andPrince Louis— to grow up as normally as possible while also preparing them for their roles within the royal family.

“George is more reserved, and Charlotte is more outgoing,” an insider tells PEOPLE. “Maybe it’s because he’s the heir and one day he might be King.”
George, 6, and Charlotte, 4, are already displaying personality traits that mimic their dadPrince Williamand their unclePrince Harry’s dynamic.
“It’s the same difference between William and Harry,” the insider adds. “Harry is much more laid-back and William is the more serious one because he will be King one day.”

The children’s varying personalities were on display at their parents’ charity sailing race earlier this month, with Charlotte playfully sticking out her tongue at one point.

“They are close in age, and they spend so much time together,” the source adds. “Playdates [with outsiders] can be tricky, so they learn to lean on each other.”
After a fun-filled summer, Charlotte was eager to join her brother at Thomas’s Battersea.
“She can’t wait to be with George at big school,” an insider previously told PEOPLE. “She is so excited about it all.”
