There are endless opportunities for toothy grins, from the very first shots we're bound to see following the baby's birth, to the christening, royal engagements and (fingers crossed!) a few candid Instagram snaps on the new Sussex account!
Could Kate and William be the royal baby's godparents?
The duke was a last-minute addition to the royal line-up in Westminster Abbey, where he joined his sister-in-law the Duchess of Cambridge on Thursday afternoon.
American-born Duchess Meghan Markle will reportedly not be in attendance due to maternity leave, though insiders speculate whether that is perhaps a convenient excuse to avoid meeting the man whom she openly criticized before marrying Prince Harry.
Jessica is Meghan's best friend, and recently shared a sweet snap of her and the Duchess at her wedding to Prince Harry past year.
Earlier this month, The Duke and Duchess of Sussex released a statement via royal correspondent, Rebecca English, stating that they have chose to keep Meghan's pregnancy and details of the royal baby's birth private.
Harry was able to travel to central London for the hour-long service, from his new home Frogmore Cottage in Windsor.
The duchess's mother Doria Ragland is said to have flown from Los Angeles to stay the couple as they await the imminent birth of the baby, which will be Doria's first grandchild and an eighth great-grandchild for the Queen.
Punters are still predicting a girl, while Coral has also seen a flurry of bets on Meghan giving birth to twins, with odds of 4-1. The publication also noted that although the royal family does not normally comment on cheating and divorce rumors, some lawyers from the palace denied the reports this time by calling them "false speculations".
"Grace continues to be the most popular selection in our name betting and it is the girls' names which are seeing the most money".
The child is unlikely to ever become king or queen, but the presence of a half-American child who may choose to hold dual nationality could shake up the royal family, just as the arrival of Meghan has had a modernizing effect on the stately but sometimes stodgy House of Windsor.
