The Royal Palace in Stockholm will certainly be busy.
Princess Sofia (32) and Prince Carl Philip of Sweden (37) have announced they're expecting their second child together, just 11 months after welcoming little Prince Alexander.
The couple, who wed in a lavish ceremony in 2015, welcomed their first child last April and shared the news of their new arrival on Instagram on Thursday.
"We are happy to announce that we are expecting a child, a sibling to Prince Alexander. We are looking forward to welcoming a new little member to our family," they said in a statement.
Sofia is set to welcome the new arrival in September. They won't be short of playdates as the next generation of Sweden's royal family is already growing with Crown Princess Victoria's children Princess Estelle and Prince Oscar and Princess Madeleine's children Princess Leonore and Prince Nicolas.
The couple, who have been together for eight years, have been vocal about their appreciation for parenthood.
Prince Carl held a press conference to confirm the birth hours after and he said he "couldn't stop" crying during his son's birth.
"Yes, actually. Of course. Couldn't stop," he told PEOPLE magazine.
"For me and my wife, this is obviously a great day with a lot of emotion. Words cannot describe."
Sofia, a former model and reality tv star, described motherhood as "amazing".
"He is very sweet and well-behaved. He’s a mixture of us both," she told Swedish publication Svenskdam last summer.
"The first time does take some adjustment. But it’s still absolutely amazing and wonderful. It changes your whole life."
