Duchess of Cambridge in mental health appeal for children

The Duchess of Cambridge has recorded a video message to mark the start of Children's Mental Health Week.

In the message, she says the stigma around mental health means that many children do not get the help they badly need.

"Both William and I sincerely believe that early action can prevent problems in childhood from turning into larger ones later in life," she says in the recording.

The duchess is patron of Place2Be - a national children's charity providing counselling and emotional help for children in schools.
