If Prince Harry and Meghan Markle do decide to attend King Charles' Coronation - then it appears they will have to find a babysitter.
The Duke and Duchess of Sussex have received an invitation to be part of the 2,000-strong congregation at Westminster Abbey, but are yet to confirm whether they will be part of the momentous day.
Despite being the grandchildren of the new King, it is believed that Prince Archie and Princess Lilibet have not been invited, with sources citing that the children are "very young".
A major issue is that Archie's birthday falls on May 6th - the same day as the Coronation.
If the Sussexes do take part in the Coronation, they will need someone to look after their two young children.
There is no official rule that states children under a certain age are forbidden from attending the Coronation of a monarch - but those royals who are very young usually stay at home.
Meghan's mother, Doria Ragland, has helped with child care in the past, so is the strong candidate to be looking after her grandchildren.
Doria is reportedly a very hands-on grandma to Archie, three, and Lilibet, one, and was indispensable to the couple when they first became parents.
The grandmother temporarily left her home in California in April 2019 and flew to London to be with her heavily pregnant daughter for a month.
Doria lives in California so isn't too far away from Harry and Meghan, and they reportedly have a guest quarters where she can stay over.
Harry and Meghan also have a nanny to look after Archie and Lilibet - and Lorren Khulamo was hired to look after Archie in the months after he was born.
The paediatric nurse and consultant, who no longer works for the couple, explained how they immediately put her at ease.
"When I got there, the way he opened his arms 'Hello Lorren!' and gave me a hug," she explained in an interview in January.
"[I thought] 'Wow, what a gentleman, what a gem', oh my goodness, I couldn't believe it."
She continued: "And when I walked in and saw Meghan I thought 'My God, what a beautiful woman'.
"I just felt so comfortable, it wasn't so formal as I expected it to be, it was just a normal home."
Aside from the kids' grandmother or nanny, another option could be to leave them with a close friends, such as tennis ace Serena Williams or chat show legend Oprah Winfrey.
Obviously, none of the Royal Family will be there to lend a hand as they will all be in attendance at the Coronation.
Archie and Lilibet may have new royal titles, but it doesn't look like they will be appearing at the Coronation along with their older cousins, Prince George, Princess Charlotte and possibly Prince Louis.
An insider told OK! that a major sticking point was how the Sussex children Archie, three, and one-year-old Lilibet were to be included on the day.
But the source explained that their inclusion in the ceremony has "never been a bone of contention" because small children don’t attend royal events of this scale "due to restlessness and tantrums".
However, one of the couple's alleged 'demands' is that Archie's fourth birthday is recognised at some point during the special day.
"Archie's birthday falls on May 6th, coronation day and the Sussexes want the family to recognise that," a source told OK!.
"The Sussexes have asked for some kind of celebration or acknowledgement to be factored into the day's plans to ensure that his fourth birthday won’t get lost during the momentous day."
However, numerous people have pointed out that Harry was playing polo on his son's birthday last year.
Harry was riding horses with pal Nacho Figueras, the Argentinian actor who appeared in the Sussex's Netflix documentary and was also thanked in the acknowledgements in autobiography Spare.
Their team, 'Los Padres', won their match at the Santa Barbara polo club against rivals Mokarow farms.
"#PrinceHarry went to polo on #Archie's 3rd birthday…don't tell us you NOW want to celebrate it…on #KingCharlesCoronation," wrote on person.
Another added: "Considering last year Prince Harry, Archie's father, played polo on his birthday, I can't quite understand the upset."
"Given that Prince Harry played polo on Archie's birthday this year, I don't think they place too much importance on dedicating the whole day to celebrating their son's birthday," said a third.
Archie and Lilibet became prince and princess earlier this month, with their new titles were revealed in Lilibet's Christening announcement.
The Duke and Duchess of Sussex's spokesman said: "I can confirm that Princess Lilibet Diana was christened on Friday, March 3 by the Archbishop of Los Angeles, the Rev John Taylor."
The christening took place privately at the Sussexes’ home in California but no other members of the royal family attended the intimate ceremony 'despite being invited'.
