For Serena Williams, it takes a village to raise her nearly 2-year-old daughter, Olympia. And one of the most important influences she has in her corner? Her big sister, Venus. Recently, Serena opened up about her Olympia's relationship with Venus and aspects of her mom life as her daughter turns 2. 
"[Venus is] great," Serena told Today at the 2019 Palace Invitational at Lotte New York Palace. "None of us grew up! We're all just a bunch of kids having fun."
Although bringing a baby into the world can change the family dynamic, the sisters agreed that having Olympia didn't shake things up too much. "I feel like things should have changed more," said Serena. Venus added that she wasn't actually wasn't surprised that their relationship had pretty much stayed the same. "Our relationship was already spectacular, so nothing had to change."
