News of her third child's arrival comes five weeks after Kondo announced her new Netflix series, titled Sparking Joy, which is set to premiere this summer. "In this show, I take my teachings beyond the home to share how the life changing magic of tidying can transform our communities, too. I can't wait for you to see it!" she shared on social media.

Kondo's bestselling book The Life Changing Magic of Tidying Up was turned into a Netflix series in 2019. She also helms the lifestyle brand KonMari.

Kondo previously spoke to PEOPLE about parenting, specifically about giving "up on perfectionism" and how she reacts when her daughters act up.

"I take the time to listen. Once they've calmed down, I ask them what's bothering them and then, to let them know I understand, I say, 'So that made you sad,' or 'That's what you didn't like.' I try to honor their feelings," said Kondo, who also said chaos is part of parenthood and "it's quite natural for kids to have tantrums — when they do, they do!"
