Princess Charlene of Monaco is often seen with her toddler twins on her official engagements and doesn’t shy away from putting her children in the public eye. Now, Charlene has opened up about how she raises her two kids.

For Charlene, a former Olympian swimmer, raising the toddler twins is a “sport.” In an interview with Paris Match magazine, she said that 2-year-old Prince Jacques and Princess Gabriella “are at an incredible age where they make demands on you without stop.”

“They want to know everything, understand everything, they ask me thousands of questions. ... They’re at an age when what they live and learn prepares them for the rest of life. They also want to try everything and bump into things all the time,” Charlene said.

“One day, Gabriella had a huge bump. And while I was caring for her, I saw Jacques banging away with tight little fists on the desk where she’d hit head, shouting, ‘Bad table!’ He’s very protective of his sister. And nothing is ever either one’s fault. They support and comfort one another. I can spend hours watching them play. They’re adorable and inexhaustible, which sometimes leaves me exhausted.”

Charlene revealed that the twins are also training with her for an upcoming July 4 charity challenge. The 39-year-old said: “At 2 years, they already know all the swimming pools in the principality where they train with me regularly.”

On Sunday, Charlene launched a new charity event to help raise money for a series of local charities she supports.

"There was a wonderful atmosphere at the track and it was exciting to watch the race down at the rail," Charlene, the wife of Prince Albert II of Monaco, told Hello! magazine. "It is great to see so many local charities who work tirelessly to support animal welfare, children and people in need benefiting from the Charity Mile."
