Serena Williams has been nothing but honest about motherhood since giving birth to daughter, Alexis Olympia.
And one of the things in particular she's been open about is feeling guilty when she's not with her daughter. This was even more apparent when Serena tweeted that she'd missed Alexis' first steps because she'd been training for Wimbledon.
And even more recently, Serena admitted that leaving her daughter to go to work is more difficult on some days than others.
Taking to Instagram, Serena wrote about the struggle of feeling like a bad mom, and how she copes with the guilt of balancing motherhood and work.
In a lengthy caption, Serena wrote: "Last week was not easy for me. Not only was I accepting some tough personal stuff, but I was just in a funk. Mostly, I felt like I was not a good mom."
Serena then said that she'd been doing research and discovered that "postpartum emotions can last up to three years if not dealt with."
But revealing that she'd spoken to her family and friends, she continued: "It's totally normal to feel like I'm not doing enough for my baby."
Opening up about being with her daughter every day but still feeling like she isn't around as much as she'd like, Serena said, "Most of you moms deal with the same thing. Whether stay-at-home or working, finding that balance with kids is a true art. You are the true heroes."
She ended the caption with a lovely sentiment, saying: "If you are having a rough day or week, it's OK – I am, too! There's always tomorrow!"
