The Duke and Duchess of Sussex welcomed their first child, son Archie, just over a month ago.
However, fans are predicting the royal couple will have another little tot next year.
Bookmaker Coral has revealed they have been "inundated" with bets and have slashed the odds on Meghan and Harry having a second baby in 2020.
Odds of the couple adding another baby into their family next year are now 10/11.
Coral spokesperson John Hill told The Sun: "We have been inundated over the last few days with bets on Harry and Meghan having a second baby in 2020, and as always with gambles of this kind, there is seldom smoke without fire."
Meanwhile, Ladbrokes have also slashed their odds on another royal baby being welcomed into the world next year to 6/1.
Spokesperson Alex Apatis added: "Baby fever could soon be taking over the Royal Family once again and despite only giving birth a matter of weeks ago, we wouldn't be surprised if Harry and Meghan have the bug."
Archie Harrison Mountbatten-Windsor was born in the early hours of Monday, May 6.
Meghan and Harry then introduced their little boy to the world in his first photocall inside St George's Hall at Windsor Castle two days later.
We have been inundated over the last few days with bets on Harry and Meghan having a second baby in 2020.
However, royal fans haven't seen much more of the royal tot since.
It's been said that Meghan and Harry could share new photos of Archie this weekend to celebrate a special occasion.
According to Hello! magazine, Meghan and Harry could treat the public to new photos of Archie to celebrate Father's Day on Sunday (June 16).
Prince Harry will mark his first Father's Day this weekend and it's likely the couple could release a new snap or multiple pictures of Archie.
Last month, Meghan celebrated her first American Mother's Day by posting a sweet snap of Archie's tiny feet.
The caption read: "Paying tribute to all mothers today - past, present, mothers-to-be, and those lost but forever remembered.
"We honour and celebrate each and every one of you. Today is Mother’s Day in the United States, Canada, Australia, New Zealand, South Africa, Kenya, Japan, and several countries across Europe.
"This is the first Mother's Day for The Duchess of Sussex."

Earlier this week, it was revealed that Meghan and Harry will travel to Africa later this year.

Meghan and Harry's tour will also include a visit to South Africa and Malawi.
It's been reported that palace aides are checking whether it's safe for Meghan and Harry to bring their baby son Archie on the trip.
