Kristen Bell shared a photo of her and Dax Shepard's two daughters, Lincoln and Delta, wearing the "RBG dissent collars" that she gave them so that they could share when they're feeling particularly disagreeable. In the caption, she wrote: "I'm very proud to be a mother to these two. Thank you @daxshepard for being the magic ingredient to their recipe. I'm forever grateful. Happy mothers day to all the moms out [there] with disagreeable kids. We are gonna be so grateful for their confidence the day they start to run the world."
