Serena Williams is known for being a powerful force on the tennis court, but these days, the competitive sports player is channelling her softer side, thanks to motherhood. The 36-year-old Grand Slam champion and her daughter, Alexis Olympia Ohanian Jr. [1] are the cover stars of American Vogue's February issue, and to say they're both serving up cuteness would be an understatement. Serena has shared glimpses [2] of how her life has changed since giving birth in September, and now she's opening up about why she's "so glad" she's raising a baby girl.

"I think sometimes women limit themselves," Serena told the fashion magazine [3]. "I'm not sure why we think that way, but I know that we're sometimes taught to not dream as big as men, not to believe we can be a president or a CEO, when in the same household, a male child is told he can be anything he wants. I'm so glad I had a daughter. I want to teach her that there are no limits." Preach, Serena!
