Royal experts are certain that the Duke and Duchess of Cambridge will add another baby to their family.
British betting company Ladbrokes is so convinced that baby #3 may soon be conceived that they've slashed the odds.
Jessica Bridge of Ladbrokes told the Daily Mail that "the sight of Kate and Wills with George and Charlotte has sent royal baby watchers into overdrive.
"A 2016 announcement seems unlikely but if the money's to be believed 2017 looks like a certainty.
"Fans of the Duke and Duchess are hoping the couple make an addition to their gorgeous brood sooner rather than later.
To that point, royal author Katie Nicholl told me that though Catherine is "definitely not pregnant at the moment, there will be another baby most likely next year."
Those close to the couple insist that they think three children would round out their family perfectly; Catherine herself is the oldest of three.
When they got engaged in November 2010, William and Catherine told ITV's Tom Bradby that they were looking forward to starting their own family.
"It's very important to me [to have a family]," Catherine said.
"And I hope we will be able to have a happy family ourselves."
Prince George was born on July 22nd, 2013, just over two years after the Cambridges got married.
Princess Charlotte came along on May 2nd, 2015.
William and Catherine raise the two children at their 10-bedroom home, Anmer Hall in Norfolk, England.
Though their "official" residence is at Kensington Palace, the Cambridges consider Anmer Hall their "primary residence" because it affords them much more privacy.
Last Saturday, the family wrapped their week-long tour of Canada's west coast. Though Charlotte and George traveled with their parents, they were only at one engagement - a children's party for military families.
Other than that, the royal children were only seen deplaning on day one, and leaving for England at the end of the trip.
Since brother and sister are so young, it made sense to bring them along on the royal tour.
This won't be the case for every tour, though.
"William and Kate are keen to keep the children in a regular routine at home," a royal source told Nicholl.
"Prince George starts school in September next year and so they knew this was really the only chance they would get to bring the children until they are much older."
