Meanwhile, the school and Place2Be charity staff also couldn't help but gush over the duchess following her visit to Lavender Primary. Middleton was apparently very "engaging" and "wonderful," as well as eager to learn more about how Place2Be, which is one of her charities, fitted into the whole school community.

"[Kate] was wonderful with the children and was keen to speak to the parents about the whole helps with their mental well-being too," Matthew Kleiner-Mann, chief executive of the Ivy Learning Trust, told People. "I introduced Place2Be to the school because I realized the important of counseling and mental well-being but didn’t have the wherewithal to do it myself.”

“The Duchess was really interested in how it worked, how Place2Be worked in a school environment and how it helps all children, not just those specifically having dealings with them day to day,” he continued.

Duchess Kate's visit comes after her brother James' revelations about his own struggle with depression. In his op-ed for the Daily Mail, the 31-year-old confessed what he went through before seeking treatment a year ago, saying that even the simplest things became too hard to do.

“I couldn’t communicate, even with those I loved best: my family and close friends,” James wrote.

James explained in his essay that being privileged and blessed did not make him "immune to depression." He also said that he is following the lead of his sister Kate, as well as his brother-in-law Prince William and Prince Harry, who are mental health advocates.

“They believe we can only tackle the stigma associated with mental illness if we have the courage to change the national conversation, to expel its negative associations," James continued.
