Sometimes Kate Middleton's work is child's play!

The 34-year-old royal toured a newly-opened medieval playground called The Magic Garden on Wednesday, May 4 in England — the only thing missing from the fun event were her two kids, Prince George, 2, and Princess Charlotte, 1!

Eight-year-old Elodie from St. John the Baptist Church of England Junior School was one of the young children spotted enjoying the 25-foot creature in the outdoor recreational space during the Duchess of Cambridge's visit. "[Kate] asked us what lessons we were missing and how school is," she told People. "She said George would love the dragon, but he would be a bit scared." Aww!
