We learned this week that Meghan Markle has a number of pregnancy rules she must follow, in the event she and Prince Harry start a family – including the rule that baby showers are not allowed.

Now, there’s another tradition the new Duchess of Sussex must get accustomed to, and it’s her new royal bedtime.

According to one of the Queen’s private secretaries, Sir William Heseltine, whenever members of the royal family stay with the Queen, they must wait until Her Majesty herself retires to bed before the rest of the royal family members may also call it a night.

If anyone did go to bed before the Queen, Sir William explained it would be considered “bad form”, revealing in an interview for a book called The Royals In Australia that “nobody felt it right to go to bed before the Queen did”.

It’s yet another royal rule in a long list of traditions that Prince Harry’s new wife Meghan must become accustomed to, and it was one particular rule that her late mother-in-law Princess Diana struggled with.

Sir William revealed, “For Diana the long royal evenings were agony.”

He continued, “There’d be an hour or so in the sitting room of everyone sitting around making conversation, and nobody felt it right to go to bed before the Queen did.

“And Diana was driven to such extremes that she’d excuse herself and go to bed, which was thought to be rather bad form, going to bed before the Queen.”
