Williams will be spending part of her daughter’s day away from home, as the athlete will be competing in this year’sU.S. Open tournamentagainst Croatian player Petra Martić on Sunday afternoon.

In a recent interview withForbes, Williams opened up about how it’s often“painful” to be away from her daughterduring long tournament days.

“Now she’s a little bit better. I think I’m a little more upset. But at the same time, she definitely still takes it a little hard. She’s still super young,” Williams said.

Serena Williams – Mother’s Day

The mother of one went on to add that while “it’s hard” to be away from her daughter, it comes with the territory of being a working mother.

“Sometimes my heart literally aches when I’m not around her. But, you know, it’s good for me, I guess, to keep working and just — to all moms out there that it’s not easy,” she said. “It’s really kind of painful sometimes. Sometimes you just have to do what you have to do.”

Although Williams did commemorate her daughter’s birthday, the tennis pro and her husbandwon’t be throwing Olympia a birthday bash.

“Olympia doesn’t celebrate birthdays,” Williams said at a press conference last year. “We’re Jehovah’s Witnesses, so we don’t do that.”

According to theofficial website for Jehovah’s Witnesses, “although the Bible does not explicitly forbid celebrating birthdays,” followers of the church “believe that such celebrations displease God.“
