The sportswoman has been candid about the reality of motherhood since the birth of her eldest daughter, Olympia Williams Ohanian, in 2017.
And following the birth of her second child, Adira River Ohanian, in August 2023, Williams has made it clear that when it comes to motherhood, some days can be a struggle.
Watch this clip of Serena Williams introducing her daughter Olympia to the world. Post continues after video.
Earlier this week, the 42-year-old athlete painted an honest picture by sharing a mental health message to followers, writing, "I am not ok today."
"And that's okay not to be okay. No one is okay every single day. If you are not ok today, I'm with you. There's always tomorrow."
The transparency around mental health and her candid storytelling surrounding her birth, pregnancy and motherhood journey has been far removed from the perfect curation of motherhood with which we are regularly presented on social media.
