Wozniacki, who returned to professional tennis in 2023 in an awaited comeback after a short retirement, has effortlessly combined her sports career with motherhood.

To mark Olivia’s special day, Wozniacki posted a series of adorable photos in her Instagram stories. The photos captured Olivia snuggling with her little brother James, hanging out with her mother, and just being her lively, confident self.
Each picture was paired with a loving caption: “This beautiful girl is 4 today!”, “The best big sister to James!”, “Competitive like her parents,” and “Happy birthday my sweet girl.”

Wozniacki Opens Up About Balancing Tennis and Family Life
During a press conference at the 2024 US Open, Wozniacki revealed how she balances the requirements of professional tennis with being a wife and mother. The Danish tennis player observed that her marriage and sporting ambitions comfortably coexist.
“Of course, marriage is a big thing, and I’m very happily married, but when you get married, it doesn’t really change your preparation for training or matches or days off,” Wozniacki said.
Wozniacki also reflected affectionately on her children, highlighting how they’ve enhanced her life and given her a newfound reason for being.
“Having kids makes a big difference. Obviously, my kids are there every day, and I’m so grateful for that. It’s the best job in the world, and I love it. I try to make sure that I’m still a 100 per cent present mum whilst also trying to balance being the best tennis player I can be. I think that’s where it can get a bit tricky sometimes,” she added.
After her US Open campaign, Wozniacki stepped away from the tour for an extended break and had planned to return at the 2025 Australian Open. However, she later pulled out, explaining that she wasn’t feeling physically well and was dealing with challenges related to her rheumatoid arthritis.
