“I realize that a lot of the conversation right now surrounds my work ethic, and I feel like I need to just make one thing clear: raising children is a job as well,” she wrote. “In fact, it’s the hardest and most rewarding job that I have ever had.

She added, “I don’t judge anyone who chooses a different route, and I hope that everyone can appreciate my choices as well.”
