Kate Middleton and Prince William are dedicating themselves to a cause very close to their hearts. As the Duke and Duchess of Cambridge continue to promote children's mental health, the couple visited with representatives from YoungMinds in London on Thursday.

In a sweet video message posted by Kensington Palace, the Royals and several members of the organization opened up about the importance of parents seeking help when dealing with mental health issues in their children.

"We're parents ourselves. I'm sure we'll face worries. We do face worries because we've got small, young children," the mother of Prince George and Princess Charlotte said. "But if those worries escalate, having that feeling that there's somebody there that's non-judgmental that can provide the professional support and that can really provide a helping hand at a difficult time, I think, is really impressive."

Her husband mirrored the sentiment, praising the work of the employees at the hotline call center.

"You've got these caring, lovely people on the phone, who listen for as long as they need to build the picture of what's going on and provide extremely good advice," he said.

Both parents want to emphasize that there's no shame in seeking help. And they want to encourage fellow parents and young people to seek assistance whenever they need it.

"What we've taken away, I suppose, is just how normal it is," Kate said.

"It's totally fine to talk about it, to seek help, and speak out," William added. "Because we're not all superheroes and there's a lot of pressure on parents. Most of it is self-made, from parents themselves, where you feel you have to handle everything. You have to show strength and resilience to everything. But there are sometimes when it all gets to be too much and you need to reach out and that's totally fine."
