"You learn to embrace the things that you maybe stopped enjoying as you became an adult," she explained. "So things become fun again."
"If you're getting a Christmas tree, that becomes a whole event. As a young adult in your 20s, you don't care about your Christmas tree. Christmas becomes just a time to drink… a lot," she added. "So having kids kind of moves it away from the drinking and back to childhood ideas of Christmas."
Wilde, who shares 2-year-old son Otis and 2-month-old daughter Daisy with fiancé Jason Sudeikis, also dished about how having kids has changed her mind about other things, like reproductive health.
"Throughout my pregnancy I became more and more involved in women's reproductive health as I became more acutely aware of how lucky I was to have the health care I needed, to have control of my choices I wanted to have," she shared.
"I became really involved in positions for reproductive health and Planned Parenthood, and… we need to protect those institutions now more than ever," she said. "Having a daughter has definitely focused my attention on what I want her rights to be long after I'm gone."
Speaking of Daisy, the newborn has become quite the star of her mom's Instagram; Wilde even shared a photo of herself breastfeeding her daughter in October.
