Royal children grow up amid palaces, travelling on private jets. They attend the most prestigious schools and have high trained nannies.

With The Royal Foundation, the pair have founded Heads Together.

It “combines a campaign to tackle stigma and change the conversation on mental health with fundraising for a series of innovative new mental health services,” according to the initiative’s website.

A parenting expert told Express.co.uk about the Cambridge couple: “Kate and William have always shown an interest in mental health and wellbeing, and their honesty in talking about their own struggles is refreshing and, in some way, unheard of for the Royal Family.

“Kate never shies away from talking about uncomfortable topics and her parenting style reflects this.

The royal helps his two small children ascend the stairs to the aircraft.

It prompted a number of fans to post their own praise. “A beautiful, loving family,” one wrote.

Another said: “William is a natural at being a father.”

“Such a good Dad,” one wrote. “The children are precious, bigger now but always precious.”
