The little prince seemed a little nervous but put tried to put on a brave face as he walked hand in hand with his father and met with Head of Lower School Helen Haslem outside of the campus.

His mother, Duchess Catherine, who just announced her third pregnancy, was noticeably absent from George’s big day, as she was not well enough to take him to school.

The Duchess suffers from hyperemesis gravidarum, or severe morning sickness, which also afflicted her in her first two pregnancies. She was forced to cancel an appearance on Monday along with the pre-planned trip to George’s first day of school.

When he arrived at the school, George politely shook hands with Haslem before taking her hand and continuing into the campus.

Thomas’s Battersea reportedly costs $23,000 a year and is known as a “a big, busy, slightly chaotic school for cosmopolitan parents who want their children to have the best English education money can buy,” according to The Good Schools Guide.
