The married actors, who share daughters Lincoln, five, and Delta, four, have teamed up with U.S. retail giant Walmart for Hello Bello, a range of affordable plant-based items, including diapers, wet wipes, shampoo and body wash, baby lotion, and bug spray.
"As a mum of two, I know how beautifully messy parenthood can be, and that's why we created Hello Bello - a line of premium, super-effective baby care products to take care of your kids from head to butt to toe," Kristen shares in a press release.
"Our products are fresh and fun. More importantly, we use plant-based ingredients and organic botanicals that are better for our kids and better for our world."
Her husband Dax adds, "We know parenting is hard enough as it is. Parents shouldn't have to choose between what's good for their baby and good for their budget."

The couple also promoted Hello Bello on the "Parenthood" actor's Armchair Expert podcast on Monday, revealing the stars had been "working for two years" on developing the goods.
"(It's) the stuff we would use on our babies - and do," Kristen explained, adding that she was the main driving force behind the project: "I'm really anal about (product) ingredients."
Pricing for items in the collection range from just under $2 (£1.50) to $24 (£18.50).
They aren't the only celebrity parents to establish baby products free of nasty chemicals - Jessica Alba has found huge success with her Honest brand, which began with baby goods and household items, and has since expanded to include cosmetics and skincare.
