Kristen Bell recently sat down with Parents.com and shared one of her proudest parenting moments, which featured a sweet moment of sibling affection between her daughters.

American actress Kristen Bell's open honesty about the unique challenges of parenthood has made her one of the most relatable and inspiring moms in Hollywood. She is the proud mother of two daughters-- Lincoln, 6, and Delta, 4. Bell is more than willing to share some of the most joyful highlights of motherhood with the world.

Bell was hosting "A Perfect Night In" event for the American Express Blue Cash Preferred Card in West Hollywood, California on May 9, when she told Parents.com about a sweet interaction between her two adorable daughters. "A couple of days ago, I think that [Lincoln] had been grumpy to [Delta] right when she woke up and it hurt my little one's feelings," Bell explained. Bell explained that later she was surprised when the situation quickly turned around by Lincoln's unexpectedly sweet gesture: "When I walked in the kitchen, they were eating cereal," Bell shared. "And there were love notes all over the table that said, 'I love you, Delta! I love you, Delta! Love, Lincoln,' because my older one was apologizing with love notes. It was pretty cute." Bell shared how happy she was that the girls have each one other and that one of her greatest hopes for them is that they will always support one another. "Seeing them hug, I imagine it's what heroin feels like," she says. "It makes your heart feel like it's going to explode. Because you're like, 'Oh yeah, I'm going to die someday, but all I want is for you guys to know you're on the same team!'" The Good Place star also revealed that one of her daughters made her really proud as she helps a little boy in her class who struggles with English as it's not his first language. The boy also has some behavioural problems, and the teacher told Bell she looks to her daughter to help calm him down: "I actually really rely on her when he's having some sort of panic, that I call her over, and I ask her if she wants to speak to him, and she speaks to him tenderly, and she gets through to him."

Bell had a conversation with her daughter about it later on. "I said, 'Do you help him when he's having problems at school?'" she recalls. "And she was like, 'Oh yeah! Yeah, I'm there if he needs me!' And it really made my heart swell. I was like maybe we're doing something right!"
