Prince William and Kate Middleton just revealed their biggest parenting nightmare

We don't blame them.

We spend so much time talking and obsessing about the royal family. What they wear, where they go and what they do - it all seems so interesting to us common folk. However, sometimes we forget that at the end of the day, the royals are just humans, like us. Take Prince William and Kate Middleton for example. Sure, they are destined to be the King and Queen of England sometime in the future... but they're also parents. And anyone who has children knows that this is not an easy job. During the week, the Duke and Duchess of Cambridge visited the BBC, to attend an engagement for Anti Bullying Week. The couple spoke about how they worry about their children, and spending time online. Obviously they don't have to worry about social media just yet, but kids of all ages are spending more and more time online these days. The Duke of Cambridge admitted working out a balance for online time was “quite difficult”. Prince William said: “We still haven’t worked out what the right balance is for online time."
