Prince George has just accomplished a milestone, as he went to his first day of prep school in southwest London.

In a moment that mimicked one of Princess Diana and Prince William 30 years ago, George was escorted to Thomas's Battersea by his father, The Guardian reported.

Missing in the first-day-of school moment was Catherine, Duchess of Cambridge, who was absent due to her severe morning sickness from her third pregnancy.

Well wishers jammed the fence outside the school to watch as the princes arrived.

The school is said to be teaching George, who will be going by the name George Cambridge, how to be kind, gain confidence, leadership and humility, The Guardian reported.

Like any 4-year-old, George looked a little unsure as he walked up to greet the head of the school. His father, despite being second in line to the throne, carried his son’s bag.

Thomas's Battersea costs $23,000 a year, CNN reported.
