It’s safe to assume that Prince William and Kate Middleton are – just like the rest of the Royal Family – currently busy preparing for King Charles and Camilla’s coronation. When the couple follow the procession to Westminster Abbey, their three children, Prince George, Prince Charlotte, and Prince Louis will be there with them.
While George will likely get a more significant role at the coronation, Charlotte and Louis can be expected to be relegated to the background given their ages. That said, the coronation could mark a historical moment for Charlotte as she might wear a crown of sorts for the first time – which would actually go against royal protocol.
