The Prince and Princess of Wales are "acutely aware" of future problems that their two youngest children could face, according to one royal expert. Princess Charlotte, 9, and Prince Louis, who will turn seven later this month, are so-called "spares" to their older brother, Prince George.

George, 11, is the oldest child of Prince William and Princess Kate and will, one day, become King. Praising the couple's approach to parenting, royal expert Jennie Bond said that Kate and William strive to give their two younger children as normal of an upbringing as possible. As reported by the Mirror, Ms Bond said: "William and Kate must be acutely aware of the problems for a royal spare. They have already shown that they have a different and modern attitude to bringing up royal children and I'm sure they will do everything to make Charlotte and Louis feel every bit as special, loved and valued as George.

Speaking of Louis - their second son - in particular, Ms Bond added: "I imagine they will encourage Louis to explore life outside the royal fold... it could be the military, but it could also be working in the charity world or whatever he finds appealing after his education is finished.

"I'm sure they will encourage him to go to University, which they both enjoyed and where, of course, they found love.

"And from there they will want him to find a life that is meaningful to him as well as appropriate for the son of a future King.

"They will try to ensure that he feels he is living a life of value, irrespective of his place in the line of succession and that will probably involve service of some kind as they have emphasised from the start that they want their children to understand that having empathy with others is not only a kindness, but is rewarding as well."
