For mother of two Elle Walker, coping with the chaos of motherhood has become her brand.
She's the creative force behind "What's Up Moms," a YouTube channel with more than 150,000 subscribers devoted to helping moms learn — and laugh.
"I just want to be part of every new mom's experience," Walker told NBC's Maria Shriver.
Her recent pregnancy-themed parody of Iggy Azalea's hit song "Fancy" went viral, with over 7.7 million views.
"Humor is everything," Walker said. "When both my kids are screaming at once, I have to consciously stop and laugh, because otherwise you just start crying."
Walker produces three videos a week, many of them sponsored, from her "production office" — a closet in her bedroom — while also caring for 3-year-old daughter Presley and her 10-month-old son Ford. "I consider myself first a mom, then an entrepreneur, then a wife," Walker said. "Oh, my poor husband!"
In the spirit of sharing the mom knowledge, Shriver made her own "What's Up" video with Walker, offering some of her hard-won wisdom from raising four children.
Shriver's advice? Keep it simple, take time to do nothing, and value yourself as a mother.
"I wish someone had told me to keep it simple. Don't do so many activities, just kind of hang with your children," she told Walker. "I got caught up in, 'I gotta go to this class and that class and this thing and that thing."
Elaborate birthday parties for children? Pass.
"You're stressing, and the kids just want to have cake," Shriver said.
She said she has no regrets about being a working mom, and wants women everywhere to value their roles as mothers. "Women come up to me and say 'I’m just a mom,'" Shriver said. "I say, lose the 'just.'"
