The four-year-old royal - who is the oldest child of the Duke and Duchess of Cambridge - started Thomas Battersea institution last week, and the youngster has taken to education like a duck to water and has not complained about student life just yet.

Speaking about his son's first few days at school to patients at Aintree University Hospital, which has been reported on Yahoo! New Zealand's website, Prince William said: "It's been an interesting week.

"George has been really easy. He hasn't said, 'Have I got to do this for the rest of my life?'"

But the 35-year-old parent is waiting to see how long George's positive attitude towards school will last, as he thinks it won't be long before he complains he doesn't want to go to class.

William added: "We are all seeing how long that lasts before he doesn't want to go!"

This news comes a few days after a suspected stalker, who is believed to be in her 40s, was arrested after she allegedly tried to break into George's private school.

Despite the commotion, the children dealt with the ordeal perfectly fine, and it was the pupils' parents who were left in "floods of tears".

William added: "Most of the parents were in floods of tears. The kids were all fine."

However, it is understood that the woman did not have contact with any of the children at the school and, although motives are currently unclear, no one was said to be in danger.

And it is believed George was not present at the time of the incident as he finishes at 12pm due to reception only attending mornings.
