Prince Louis is keeping Prince William and Kate on their toes

Cape Town - Little Prince Louis may only be a year old, but he is already keeping his royal parents on their toes.

During a visit to Bletchley Park - a secret WWII spy base - on Tuesday, Kate admitted that Prince Louis gave them quite a scare recently when he climbed up a high slide when she turned her back for a moment.

The duchess added that when she gave birth to George, she was "naive" about how important "childhood development" is.
