William has previously spoken out about their family unit, where he too described them as "very normal," and that there was a time and place to tell George he will be King – making it clear that right now, the Cambridge children are not aware of their royal position.
Talking to the BBC in April 2016, William said: "As far as we are concerned, within our family unit, we are a normal family."
The dad-of-three continued to explain that they are waiting for the right time to tell George that he will one day be a king.
He explained: "I love my children in the same way any father does, and I hope George loves me the same any son does to his father. We are very normal in that sense. There'll be a time and a place to bring George up and understand how he fits in, in the world. But right now it's just a case of keeping a secure, stable environment around him and showing as much love as I can as a father."
