Prince Harry has reportedly realised there is "no plan B" other than patching things up with King Charles and the rest of the Royal Family, and he is keen for his children to get to know their cousins and grandparents.

A royal source told OK! magazine that the California-based Duke wants to "put an end to the feud" with his immediate family and that he "regrets the way that things have turned out".

This comes after Harry's whistle-stop tour of the UK following the King's cancer diagnosis. The 39-year-old spent less than 45 minutes with his ill father, and did not meet up with his brother. The Prince is now safely back in the US and recently appeared at the NFL Honors in Las Vegas.

On the Prince's apparent change of heart over his relationship with his family, the source said!: "I think there's no plan B for Harry, patching things up with his family is the only option. It's finally hit home how difficult it will be to repair the damage caused by the various swipes at his family over the years."

Leading royal commentator Jennie Bond shares the source's sentiment and speculated on whether recent events around the King's health has changed Harry's perspective.

She said: "Harry has spoken about wanting his children to understand their legacy and to feel equally at home in the UK as they do in America. By now, they must be proper little Californians with minimal understanding of their British heritage.

"Life events like this, though, focus the mind, and I'm sure Harry will be dwelling on the fact that his children have virtually no relationship with their paternal grandfather - or maternal grandfather - at the moment. Time and life are marching on, and scares like this will certainly make Harry think hard about the future."

However, the royal expert and author of The Platinum Queen, added that despite the 75-year-old monarchs illness, relations between him and Harry will not thaw easily.

She said: "We all hoped for some kind of fairy-tale reunion to come out of the shock news that Charles has cancer, but life is not like that.

"These are complex family relationships which are not going to be resolved with the wave of a wand."
