Prince William and Kate Middleton could have another baby next year. Announcement regarding the Duchess of Cambridge’s fourth pregnancy may be made sometime at the end of 2019.

Following the birth of Prince Harry and Meghan Markle’s son on May 6, Prince William and Kate expressed their excitement over the newest addition to the royal family. This led bookies Betfair to offer odds of 7–2 on the Duke and Duchess of Cambridge having a fourth child in the coming months.

Katie Baylie, a spokesperson for Betfair, told Express that the arrival of the Duke and Duchess of Sussex’s son could have left the parents of Prince George, Princess Charlotte and Prince Louis feeling broody again. The couple also celebrated the first birthday of Prince Louis last month, which means that it could be time for them to have another baby.

“A year on from the birth of Kate and William’s third child Louis, Harry and Meghan’s firstborn is the biggest story in the world right now,” Baylis said. “The Duke and Duchess of Cambridge have warmly welcomed the new arrival and now there are speculations that the little royal may have got the couple feeling broody again. We make it 7/2 that Kate and William will have a fourth baby which would excite royal fans who can’t get enough of royal babies,” she added.

Prince William and Kate first welcomed their eldest child, Prince George, in July 2013. Less than two years later after, Kate gave birth to Princess Charlotte, in May 2015. Prince Louis was born in April 2018.

All three pregnancies were difficult for Kate because she suffered from hyperemesis gravidarum or extreme morning sickness. But even though her pregnancies were challenging, a friend close to the mom of three said that Kate is willing to go through it again just to have another baby.

“Catherine would like another baby,” the Duchess’ friend told Daily Mail. “She loves children and is prepared to put herself through another pregnancy even though they have been complicated by severe morning sickness in the past,” the friend added.
