Ahead of the U.S. Open, tennis superstar and new mom Serena Williams sat down with NBC’s Stephanie Ruhle to open up about recent challenges facing her as an professional athlete and first-time parent to daughter Alexis Olympia. Williams said she seeks comfort in knowing she’s not the only one facing hardships in motherhood, referencing the moment she missed her baby’s first steps and many fans came to her support. “I didn't realize that it was almost more normal to miss it than to make it,” she said. “So I really rely on everyone's help out there.”
