Serena Williams on the moment her daughter 'humbled' her

Serena Williams is a living legend. She has been named number one in tennis eight years in a row. She holds the most Grand Slam titles in singles, doubles and mixed doubles. She is the world's highest paid female athlete.

She's arguably one of the world's most impressive people.

This is exactly what happened to the tennis champion on a recent flight with her daughter.

LISTEN: The latest episode of the Honey Mums podcast touches on moody teens and navigating divorce.

Williams shared the story in a post on Twitter, writing, "Kids humble us. The other day on a flight home Olympia insisted on running up and down the aisle and when I finally got her to sit still, she threw up all over me."

Oh no.

Encouraging other parents to come forward and share their experiences, the tennis champion wrote, "#ThisMama would love to hear your stories of motherhood… even ones like this! Share and tag them with #ThisMama."

Mums and dads alike responded to Williams' callout with their own hilarious misadventures in parenting.

Megan wrote, "My daughter and I planted some seeds together, hoping to grow flowers. I went outside to water them and told her to watch. She locked the sliding glass door on me. #ThisMama got locked out of the house by her two year old."

Another mum, Josie, wrote, "I took my kids to work with me every day. My husband and I would discuss work at home. One day my oldest walked around the office and told one of my employees “my mommy is going to fire you”. From that day on we talked in code words. #ThisMama."

Kids certainly humble you, that's for sure.
