George and Charlotte are increasingly accompanying their parents on public outings now that they are older. Younger brother,Prince Louis, 3, often comes along, but he was deemed too young for Tuesday’s memorial service.

The Cambridge kids are “all very polite children,” added the family friend, “but they have a little twinkle in their eyes. They have all the right ingredients.”

According to a royal source, William “is conscious of making sure the children have as normal a relationship with their parents as they can.”
While Kate rightly gets plenty of credit, some of those close to the couple say William’s role as co-parent should not be underestimated. The Duke of Cambridge is “pretty grounded as well,” said a source who knows them.
