The family waited as the Queen's coffin departed the gothic church and began the procession to Wellington Arch, where the senior members of the royal family curtsied in unison. However, it appears young Prince George and Princess Charlotte didn't receive the royal memo, and bowed and curtsied moments later after Charlotte spotted Sophie at the last moment, swiftly dipping into an adorable curtsy, as Prince George followed suit with a head bow.

The royal siblings have been helping each other out as they accompanied their parents, the Prince and Princess of Wales, to their great-grandmother's funeral. In another moment at Wellington Arch, the pair were filmed exchanging words as they waited for the coffin to be placed onto the royal hearse, where Charlotte can clearly be seen saying: "You need to bow" to George, who appears to be listening to his sister intently.
