Harry and Meghan caused a global sensation in January when they announced their intention to step down as senior members of the Royal Family.
The couple took their son Archie to Vancouver, Canada, for an extended break in November 2019.
They spent Christmas in North America with Doria Ragland, Meghan’s mother.
Whilst Harry and Meghan did make two trips back to the UK in early 2020 they did not bring Archie.
In March the couple and their son moved to Los Angeles shortly before the city went into coronavirus shutdown.
Speaking to the Daily Mail a friend of Prince Charles revealed the heir to the throne regrets not seeing more of his grandson.
They said: “The Prince of Wales enjoyed popping into Frogmore Cottage to see his youngest grandchild and is sad that he hasn’t seen him for so long.
“He has missed much of his development since he is now growing up in the USA.

“Other members of the family are very sad at not seeing him.
“Everyone really misses Archie – they feel it’s particularly sad for the Queen and Prince Philip.
“Harry always said he looked forward to raising his family with William’s – which of course is not now happening.”
Archie was born on May 6 2019. The ongoing coronavirus pandemic has severely restricted travel between Britain and North America.

Harry and Meghan had been living at Frogmore Cottage, on the Queen’s Windsor estate, prior to stepping down from front line royal duties.
They have since repaid the British taxpayers’ money that was spent renovating the property before they moved in.
Recently the Duke and Duchess moved to a new £11.2million property to the north of Los Angeles.
The luxury property came complete with a swimming pool, tennis court and children’s cottage.
