Serena Williams reaches out to other moms for help with baby Alexis' teething pain

— -- Even 23-time Grand Slam singles champion Serena Williams was at a loss over how to help her baby, Alexis, through teething pain.

Admitting she was "stressed," the new mom reached out to fellow mommies on social media Sunday.

"Teething- aka the devil - is so hard. Poor Alexis Olympia has been so uncomfortable," the tennis star wrote alongside a photo of her daughter. "She cried so much (she never cries) I had to hold her until she fell asleep. I've tried amber beads... cold towels.... chew on mommies fingers.... homeopathic water (lol on that one) but nothing is working. It's breaking my heart. I almost need my mom to come and hold me to sleep cause I'm so stressed. Help? Anyone??"

Responses from fans ranged from rubbing whiskey on the gums to using baby Orajel to letting the baby gnaw on a Milk-Bone biscuit for dogs.

Williams, 37, and husband Alexis Ohanian, the co-founder of Reddit, welcomed their first child in September. Together since 2015, they wed in a star-studded ceremony in New Orleans last month.

Sunday was not the first time that Williams has reached out to other moms for parenting advice.

Earlier this month she tweeted, "Fellow moms: How long did you breastfeed? Is it weird that I get emotional when I even just think about when it’s time to stop?"

One of the responses came from Broadway star Audra McDonald. "I nursed my older daughter until she was almost 2. Still going with my 1 year old right now," she tweeted. "You’ll know when it’s time to stop. Enjoy! She is beautiful!"

Though she may be enjoying motherhood, Williams is already training to return to the court. She is registered for the January competition to defend her title, according to the organizers of the Australian Open.

She beat sister Venus Williams last year while pregnant.
