Serena Williams asks Twitter followers for breastfeeding advice

On the tennis court, Serena Williams is a formidable, world record-holding champion.

But when it comes to raising children, there’s plenty she’s still uncertain about - which makes her just like any other first-time mum.

The athlete and her husband, Reddit co-founder Alexis Ohanian, became parents in September with the arrival of their daughter Alexis Olympia Ohanian, Jr.

“I nursed my older daughter until she was almost 2. Still going with my 1 year old right now. You’ll know when it’s time to stop. Enjoy! She is beautiful!” another posted.

Many encouraged Serena to be guided by her daughter - and by her own instincts.

“You'll know when. Trust your instincts. You will miss it (the convenience, the bonding) but I found there was a point where I wanted my body back,” one mum shared.
