Why Serena Williams' daughter Alexis teething is breaking her heart

Even with the joys of motherhood, there can be a few frustrations along the way.

Serena Williams shared one of those on her Instagram on Sunday, where she detailed the painful teething process her baby daughter, Alexis, is going through.

"Teething -- aka the devil -- is so hard. Poor Alexis Olympia has been so uncomfortable. She cried so much (she never cries) I had to hold her until she fell asleep," the tennis star wrote in the caption alongside a sweet photo of three-month-old Alexis.

Williams went on to detail the various remedies she's tried to ease her daughter's pain. 

"I've tried amber beads... cold towels.... chew on mommies fingers.... homeopathic water (lol on that one) but nothing is working," she continued.

For the first dress When Anna Wintour asked me what I wanted to wear I said "a cape" I just want to wear a cape" she said: "well Sarah Burton with @alexandermcqueen is the one for you.” Thanks Anna. Thanks Sarah. I felt like a princess and superwoman all at once. 📸: @mistadubb @ericamelissa_

@serenawilliams: You are the greatest of all time, not just in sport--I’m talking about as a mother and as a wife. I am so excited to write so many more chapters of our fairy tale together. And my whole life I didn’t even realize it, but I was waiting for this moment. And everything that I have done, everything that I am so proud of in my career, and in my life, for the last 34 years, pales in comparison to what we’re doing today. And I am so grateful, and I am so in love. 📸 @melbarlowandco @allanzepedaphotography

The newlywed ultimately reached out for recommendations from her followers on the site.

"It's breaking my heart," she wrote. "I almost need my mom to come and hold me to sleep cause I'm so stressed. Help? Anyone??"

Luckily, teething is just a phase and Alexis looks like she's a toughie. Earlier this week, on her official Instagram, baby Alexis hit the gym with her dad, Alexis Ohanian, staring fiercely into the camera.

"Dad & I hit the gym hard today," the photo's caption read.
