What’s almost as cute as Prince George playing with bubbles? Hearing a proud Prince William talk about his three-year-old son. The Duke of Cambridge, who is currently on a solo trip in Vietnam, got candid about parenting the Royal Family’s biggest stars George and Princess Charlotte in an interview with Talk Vietnam.

“George is a right little rascal sometimes, he keeps me on my toes, but he’s a sweet boy. And Charlotte, bearing in mind I haven’t had a sister, so having a daughter is a very different dynamic.”

As for his take on parenthood? “There’s wonderful highs, and wonderful lows. It’s been quite a change for me personally…I’ve struggled at times,” he told the show’s host. 

At least he has his wife, DoC Kate Middleton, to help him out.  Watch the full interview below.
