At the tender ages of 9 and 7, Prince George and Princess Charlotte joined their parents, the Prince and Princess of Wales, and other family members in following Queen Elizabeth II’s coffin into Westminster Abbey Monday for her globally televised state funeral.

William and Kate are said to have thought long and hard about whether to bring their two oldest children to the funeral, where they would be in the presence of world leaders and seen around the world.
