The couple have not been afraid to remind parents and teenagers that they too would seek help if their children needed it. William and Kate used the opportunity at the helpline calling center to remind those coping with the stress of growing up that there should be no shame in asking for help.
Kate added: “As a parent and as a mother, having that feeling that there is somebody there that is non-judgmental, that can provide the professional support, and that can really provide helping hand at a really difficult time.”
Duchess Kate looked regal in a scarlet red LK Bennett dress, the second day in a row she wore the designer to an engagement.
Prince William was also moved by the stories he heard on the helpline and the parents he and his wife spoke to.
"It is important that parents understand that you can’t be brilliant at everything. It is totally fine to talk about it and to seek help and to speak out because we’re not all superheroes. There is a lot of pressure on parents, and most of it is self-made by parents themselves, where you feel you have to be able to handle everything. You have to show strength and resilience to everything. But there are some times when it all gets too much and you need to reach out, and that’s totally fine," he said.
"I know how you feel, I miss my mother every day," he said, adding: "It's OK to feel sad."
While the future King and Queen listened to both the teenagers and parents they met over their two days of engagements there were some lighter moments also.
Prince William was asked by one young mother for Harry's phone number for her daughter. He joked "Oh no, you don't want that."
Kensington Palace said in a statement: "Through the Heads Together campaign, Their Royal Highnesses are keen to build on the great work that is already taking place across the country, to ensure that people feel comfortable with their everyday mental wellbeing, feel able to support their friends and families through difficult times, and that stigma no longer prevents people getting help they need.”
