Kate Middleton

A new PSA released by Place2Be, a UK organization that supports children's mental health in school, features the Duchess of Cambridge.

In the video, Kate Middleton speaks out in support of children who may be facing stress or anxiety as a result of issues such as bullying, family violence, or tragedy. This week, from February 16-22, marks the UK's first Children's Mental Health Week (in the U.S., it's May 3-9).

"Without support, the effects of these challenges can be traumatic, leading to serious issues such as anxiety, depression, addiction and self harm," Middleton says. "The stigma around mental health means that many children do not get the support that they so badly need ... We need to help young people and their parents understand that it's not a sign of weakness to ask for help. A child's mental health is just as important as their physical health."

Middleton is very involved in charity work related to children. When the Duke and Duchess visited New York City for the first time in December, Middleton toured a children's development center in Harlem with Mayor de Blasio's wife, Chirlane McCray.
