Qai Qai, the doll of Serena Williams’s daughter, is one of the early headliners of the Australian Open coverage. "I was just thinking I want her first doll to be black," said Ms. Williams. "Her heritage--obviously she’s mixed, she’s Caucasian and black, but I feel like that was her first doll, and her second doll would be Caucasian. I always want to teach her love.... Humans should always have love for each other, no matter what color they are.”
