Although Meghan Markle and Prince Harry have enjoyed watching baby, Archie Harrison Mountbatten-Windsor grow before their eyes, the couple is reportedly in a rush to expand their family, and give their son a sibling.

Following Archie’s birth in May, Meghan and Harry have gushed over the joys of being parents. Bookies believe the couple is so happy that they could announce Meghan’s second pregnancy before the end of the year.

According to Express UK, bookies have slashed the odds of the couple welcoming a baby in 2020 from 2/1 to 4/6.

“Harry and Meghan have made it clear they want to add to their family, and the odds suggest the pair are in a hurry to give Archie a brother or sister,” Alex Apati of Ladbrokes Gambling company revealed.

Although Prince Harry claimed the couple only plans on having a maximum of two children, royal expert, Katie Nicholl believes the Duke and Duchess of Sussex will have a big family.

“I think it’s probably a little premature to be speaking about a second baby. That said, sources close to the couple told me that they really would love to have a big family,” she told Entertainment Tonight.

Although Nicholl claimed Meghan and Harry are “amazing parents” to Archie and are “loving parenthood,” the 38-year-old may need some time before she gets pregnant again.

“They absolutely want siblings for Archie, so possibly we will have a pregnancy announcement for Meghan and Harry sometime next year,” the royal expert revealed.

In the past, medical experts have advised Meghan to allow her body time to recover before she considers getting pregnant again.

In April, Julie Jomeen, a professor of midwifery at the University of Hull, told Express UK that women over the age of 35 should wait at least a year before getting pregnant again to decrease their chances of having a miscarriage.

“The issue is, of course, that older mums are more likely to plan to have babies closer together as they don’t have the same luxury of time in terms of their fertility, as women still in her twenties would have,” the professor revealed.

“However, the general health of the mum is an important factor here in risk. Ultimately, it has to be a woman’s choice, what is important is that they are aware of the evidence around birth spacing, and that they make their choice based on good evidenced-based information.”

While there is no telling if or when Meghan and Prince Harry will make another baby announcement, it appears the couple is content being a family of three.
