See Serena Williams’ cutest moments with her daughter, Olympia

Williams calls 4-year-old Olympia her "little twin," and they have the twinning pictures to prove it.

Serena Williams is a proud mom of one to her 4-year-old daughter, Alexis Olympia Ohanian Jr., whom she shares with her husband, Alexis Ohanian.

On Sept. 1, 2017, the tennis star and the Reddit founder welcomed their daughter into the world. (Olympia's birthday makes her a Virgo, if you're curious). When she was born, her father said in an Instagram post that she was already acting like her "mama’s perfect sidekick."

Over the years, Williams has shared moments from Alexis' childhood, like her forays into tennis (check out that backswing), her visits to the U.S. Open and red carpet, and the moments she's been there for her mom. They even created a popular doll together, Qai Qai.

When Williams announced her retirement from tennis in Sept. 2022 via an essay for Vogue, she cited wanting to grow a family as her primary reason.

Olympia is ready for a sibling — Williams said her daughter sometimes says she wishes to "be a big sister" under her breath. But for Williams, the choice to step back from her career to focus on family was a difficult one.

"Believe me, I never wanted to have to choose between tennis and a family. I don’t think it’s fair. If I were a guy, I wouldn’t be writing this because I’d be out there playing and winning while my wife was doing the physical labor of expanding our family," she wrote.

Until now, Williams, who was two months pregnant when she competed in the 2017 Australian Open, had balanced motherhood and tennis. "But I’m turning 41 this month, and something’s got to give,” Williams said. "I definitely don’t want to be pregnant again as an athlete. I need to be two feet into tennis or two feet out."

As for when the Williams-Ohanian family will welcome another little one? Williams shared that she and her husband were already trying for a baby.

“We recently got some information from my doctor that put my mind at ease and made me feel that whenever we’re ready, we can add to our family,” Williams wrote.

Stay tuned for more — but in the mean time, here are some of Williams' sweetest moments with her little girl.
