Her parents escorted her to Campus Manilla in Stockholm. They took her to a red-and-yellow tram, which took her off to school with classmates and a teacher. And Princess Estelle appeared to fit right in with her new classmates.

The Swedish royal family posted pictures of Estelle in class on their official Instagram page.

According to The Local Sweden, Campus Manilla is a school funded by the Swedish government, but has become a “go-to school for Stockholm’s super-rich.” Over the summer, the school has dealt with some controversy, as the school’s founder and headmistress resigned after conflicts with the board and parents.

Estelle, who is next in line for the throne after her mother, is starting at a preschool class there this year. "It's a decision the Crown Princess couple has taken," royal spokesperson Margareta Thorgren told Expressen in May. "Nobody in the royal family has gone there before, it's a relatively new school.”

Prior to her first day of school, Princess Estelle enjoyed an idyllic family vacation with her two-year-old brother, Prince Oscar, and their parents. Photos from their trip were released earlier this week.

The images were taken in July at Solliden Palace in Öland, where the family of four often retreats for the summer, People reports. The sweet moments include hikes in the woods, boat rides, and walking through a field of flowers. One photo even features Oscar on a white horse—and he's really enjoying it.
