The Duchess of Cambridge has recorded a special video message to raise awareness of children's mental health.

Kate is an ambassador for the children's charity Place2Be, and thinks more needs to be done to help kids with their mental health.

She says the "challenges facing children here in the UK can often feel overwhelming".

At the start of Children's Mental Health Week, the Duchess doesn't think all kids get the help they need.

She and the charity want people to talk more openly about their problems this week.
