Prince George and Princess Charlotte are apparently too young and energetic to focus on one thing for too long!

During the royal family's highly-publicized Canada tour, Prince William admitted his two kids have very short attention spans!

On Friday, Sept. 30, the Duke of Cambridge and his wife, Kate Middleton, chatted with new moms at Haida Gwaii Hospital and Care Health Centre. While there, one mother brought along her three-year-old daughter, who adorably played with toy bricks while the adults spoke. Kate, 34, watched the little girl and said, "George would love those," according to Us Weekly.
