Serena Williams: I can't figure out a stroller!

She might have won 23 Grand Slam singles titles on the tennis court, but aspects of motherhood are proving a challenge for Serena Williams.

Grand slam titles? No problem. Olympic gold medals? Too easy! Using a stroller with your new-born baby? Yep, that's the greatest challenge Serena Williams has ever faced.

The 23-time singles' major champion gave birth to her first child in September, having won last year's Australian Open while in the early stages of pregnancy.

Williams is not at Melbourne Park to defend her title, as she regains full fitness after a difficult birth in which she revealed she suffered blood clots after daughter Alexis Olympia was born on September 1 last year via emergency C-section.

Serena has done, and won, it all in the world of tennis, but it seems some aspects of motherhood are proving tougher to master.

She posted on Twitter: "I've conquered a lot of things... blood clots in my lungs- twice... knee and foot surgeries... winning grand slams being down match point... to name just a FEW but I found out by far the hardest is figuring out a stroller!"

Williams is expected to return to the court in a one-day tie-breaker event at New York's Madison Square Garden in March, ahead of entering the BNP Paribas Open in Indian Wells.
