However, the Middleton’s could have a modest celebration at home as the couple spend lockdown away from Kate and their grandchildren, Prince George, Princess Charlotte and Prince Louis. Carole told her Instagram followers it was “down to husband Michael” to mark her 66th birthday in a special way during “the cold, dark days of winter”.
The honest insight was shared on her family business Party Pieces’ Instagram profile.
In the post, Carole wrote: “If, like me, your birthday falls during the cold, dark days of winter, your loved ones can still make the day full of surprises.
“Our customers have been transforming their surroundings with our sparkly backdrops and bright balloons for small ‘at-home’ parties for their household.
“It may not be how we imagined we would be celebrating, but a little effort can still lift the spirits and bring some joy.
“This year it’s down to my husband to help me mark my day – no pressure!”
The post comes as a new documentary claimed the Middletons will spend the most time with Prince William and Kate’s children.
In Channel 5’s When the Middletons Met the Monarchy, royal commentators Jennie Bond and Tom Quinn predicted the royal children will have a strong influence from her maternal family.
Mr Quinn said: “I suspect everyone thinks that in terms of the children, the royal family will inevitable have the most influence, but that is entirely wrong.
“It will be the Middletons that have the influence, because the royal family is too formal, it’s too stuck in its ways.”
Ms Bond added: “I suppose there is a little tension at times between who gets to see the grandkids the most.
“Kate will always turn to Carole for help, advice guidance, and just get together and romping around with the kids – possibly before she would get together with Camilla and Charles.”
Royal author Richard Kay also weighed into the discussion highlighting Carole and Michael Middleton’s importance in Prince William’s life.
He said: “Prince William has said, ‘Look I am not always going to be available for the Royal Family, I have another family and that is Mike and Carole Middleton and that is very important to me and Kate and my children’.”
Royal commentator Ashley Pearson explained that the Cambridges were giving their children a “modified” upbringing, that will resemble more the Duchess’ own childhood as an upper-middle class person.
