"Working and being a mum is not easy. I'm often exhausted" Serena Williams says

Serena Williams shared a new photo of her cradling her sleeping daughter as she opened up about how hard it is balancing motherhood with a career.
 The professional tennis player wrote: "I am not sure who took this picture but Working and being a mom is not easy. I am often exhausted, stressed, and then I go play a professional tennis match. We keep going. I am so proud and inspired by the women who do it day in and day out. I’m proud to be this baby’s mama @olympiaohanian. #nofilter#nomakeup #nohairbursh lol #justme."
This comes after Serena's coach, Patrick Mouratoglou said  Serena's team might have to change their strategy because she hasn't won a Grand Slam title since returning to tennis after childbirth.

 "We have to accept the fact that it is not working," said Mouratoglou.
 Speaking to BBC Sport, he added: "Maybe come back with a different angle, a different strategy and different goals so she can make it.
 "She does feel positive, she feels negative too because it is a failure when she doesn't win a Grand Slam.
 "We have to face reality, but she is positive that she can make it otherwise she probably wouldn't be on a tennis court anymore.
 "She believes she can make it and I believe it too. She's not that far, but we have to change a few things."
