Serena Williams and her daughter, Alexis Olympia, are featured on the February issue of Vogue Magazine.

The tennis star shared the cover with social media followers on Wednesday and wrote, “This is a moment I will never forget.”

In the accompanying article, Serena opens up about the health complications she faced after delivering her baby girl, and the difficulties of motherhood.

“Sometimes I get really down and feel like, Man, I can’t do this,” she says. “It’s that same negative attitude I have on the court sometimes. I guess that’s just who I am. No one talks about the low moments—the pressure you feel, the incredible letdown every time you hear the baby cry. I’ve broken down I don’t know how many times. Or I’ll get angry about the crying, then sad about being angry, and then guilty, like, Why do I feel so sad when I have a beautiful baby? The emotions are insane.”
