Serena Williams' daughter steals the show walking & playing with baby doll in recent video

The tennis star welcomed her daughter almost a year ago, and has formed an incredibly close bond with the adorable tot since her birth, even revealing she hasn't spent a day without her.

Serena Williams and her then-fiance, Reddit cofounder Alexis Ohanian, welcome their daughter, Alexis Olympia Ohanian Jr., on September 1, 2017. Since then, they've shared plenty of updates on the adorable little girl.

Olympia - as her parents are calling her - is already quite the jetsetter, having taken her first trip on a private plane when she was just 10 weeks old. Since then, she has crossed the ocean to the UK for the royal wedding and for Wimbledon.

And even on two legs she appears to be quite the busy bee. A recent video posted to Instagram of the tot has her running about a kitchen, carrying a doll with her.

She was wearing a light pink dress, and toddling about the wooden floors with her doll in hand. At one point she contemplated testing out the stairs, before evidently deciding that was still a bit beyond her reach and dropping her doll.

Olympian then did an about turn and headed back towards the kitchen, where she dropped her doll under a cupboard and continued on on her own.

Williams recently shared on Twitter that she has not spent a single day away from her daughter, despite a busy training and competition schedule.

But even though she has seen her baby girl every day since her birth, she did miss one major milestone that absolutely devastated her.

While in the UK, she was practicing for a match at Wimbledon when her daughter took her first steps. She quickly took to Twitter again to share how heartbroken she was by this.

Fortunately for her, plenty of twenty-first century working mothers decided to step in and offer her some much needed words of comfort.

Williams was so grateful for the outpouring of support that she publicly thanked everyone for the kind words during a press conference at Wimbledon.

"It was so positive. So many people, basically everyone in the mentions was like, 'Oh, so did I. It’s no big deal'. Or, 'I was at work, I was here.' I was just like, 'Wow.' I didn’t know that was a common thing. I felt really glad that I posted that. I instantly felt better from all the moms and dads that were posting that it’s totally normal," she said during a press conference at Wimbledon.
