Meghan Markle and Prince Harry’s fans are positive that the couple will welcome their second baby next year.

The Duke and Duchess of Sussex have welcomed their firstborn in May. However, their fans are already talking about their next bundle of joy. Bookmaker Coral said that fans are “almost certain” that baby Archie will have a sibling soon. Bookmakers are offering 2/1 on the baby announcement coming in 2021 and 5/1 for 2022.

“It’s almost certain that Meghan and Harry will add to their blossoming family in the next few years and we think a second pregnancy is most likely to come next year,” Harry Aitkenhead of Coral’s said. “It’s 8-1 for Meghan to announce she is expecting again by the end of the year and whilst the odds may be long you can’t rule it out.”

Aitkenhead said earlier that the couple is still in the very early days of parenthood but they are convinced that baby Archie won’t be their only child. Their favorite year when the couple will make their next baby announcement is 20/20.

“We make 2020 the favourite for the year that they announce they are expecting a second child,” Aitkenhead said earlier. “The new Royal arrivals have been arriving thick and fast over the last few years and it is 8-1 that Meghan announces before the end of the year that baby number two is on the way.”

Markle is already 37 years old and moms at that age are advised to not get pregnant so soon as women over 35 who conceive just six months after their previous birth have a 1.2 percent risk of maternal mortality compared to their younger counterparts. Thus, the new mom should wait for a year before having another baby.

However, the mother’s general health is an important factor in the potential risk during pregnancy. It is still the woman’s choice to be aware of birth spacing so they can make their choice “based on good evidence-based information.”

Aside from Markle, royal fans are looking forward to hearing Kate Middleton and Princess Eugenie’s pregnancy announcement. In April, Sarah Ferguson’s youngest daughter was photographed with what looked like a baby bump, but Princess Eugenie hasn’t confirmed the pregnancy rumors yet.
