Duchess Kate and Prince William were keen on their mirroring their own childhoods and always planned on keeping their children close in age, it has been revealed.
According to sources, Kate's only a year older than Pippa. William is Harry's elder by just two years and the Royal couple always planned their own family on the same lines, the Mirror reported.
The 32-year-old, who believes her continuing close relationship with sister Pippa is down to the fact that they were born just a year apart, hopes her first son George, now 13 months, and the new baby will have the same strong bond that she has with her own sister.
The insiders also said that Prince William also believes his own rapport with Harry has been helped by their relatively close ages.
