In a recent interview in the UK Prince William has shared how he's been getting his young kids, Princess Charlotte, Prince George and Prince Louis to bed on time.
"Last night we started watching one of David Attenborough newest documentaries." Prince William said.
"It's amazing at bedtime when I can crowd the children, just shouting 'we're going to watch one of David's documentaries' and they come herding in."
"It's the easiest way to catch my children and get them ready for bedtime."
So if you're struggling to get your kids to bed on time, this could be a good way to get them all in one room and get them to bed!
