Even being prime minister can't stop you from making a mistake every parent dreads - leaving your child behind.
It's been revealed that David Cameron and his wife Samantha left their daughter Nancy in a pub after having Sunday lunch.
Downing Street said the couple were "distraught" when they realised eight-year-old Nancy wasn't with them.
They realised the mistake when they got back to their nearby country home and Mr Cameron returned to collect her.
The incident happened two months ago. The pair left the Plough Inn in Cadsden, Buckinghamshire, in separate cars - and both thought the other had Nancy.
The Camerons had been out with their three kids and two other families.
It's thought Nancy was in the pub without her parents for about 15 minutes, but she kept herself busy by helping out the staff!
