Kate Middleton won't accept gifts during royal visits

It's pretty important

We're pretty clued up when it comes to all things royal. From what goes on behind the scenes Buckingham Palace, to following protocol, we'd say we're in the know when it comes to their very interesting secrets.

For example, did you know that the Queen has banned this ingredient from the royal kitchens? Or why Meghan Markle often wears black for official duties?

And then there's the real reason that Prince William and Kate Middleton don't hold hands in public, but Meghan and Prince Harry do.

But just when you thought you knew all there was to know, we've got another nugget of royal wisdom for you.

Kate Middleton won't accept gifts from members of the public during royal visits.

Why?

When the Duchess of Cambridge returned to work after giving birth to her third child, Prince Louis, she attended Sayers Croft Forest School and Wildlife Garden in Maida Vale, London, where she met local school children - and had the sweetest answer when one asked by one child why the photographers were taking snaps of her.

However, royal protocol states that when it comes to receiving presents things can get pretty complicated.

The Royal Family website reads: "Gifts offered by private individuals living in the UK not personally known to the Member of the Royal Family should be refused where there are concerns about the propriety or motives of the donor or the gift itself."

Reportedly, the royals are only allowed to keep hold of gifts sent by the public if their value is less than £150, and items like flowers and certain foods are permitted.

According to the BBC, all gifts must be used by the Royal Family, used for displays, or given to charity or members of staff.

Just imagine the number of teddy bears they must have collected over the years...
