Bell, who appeared on the 'Say Yes with Carla Hall' podcast, revealed that Lincoln, seven and Delta, five, love drinking non-alcoholic beer because it makes them feel closer to their dad, who has been sober for 16 years.
"I'm going to get a lot of flak for this. And let me start by saying I don't care," the Frozen actress said.
"You're welcome to tell me I'm a terrible parent. I don't care. I'm a great parent, I think. I'm learning every day… and let me stress that it's non-alcoholic."
The Good Place star explained that when they first had kids, Shepard would walk around the neighbourhood with the baby and a non-alcoholic beer.
"The baby would paw at it and put the rim in her mouth," she said. "It's a sentimental thing for my girls, right? It makes them feel close to their dad."
Bell says her and her husband use their unusual choice of drink as an opportunity to teach the girls about sobriety.
"We talk to them very much about [Dax's] sobriety and the importance of it and why Daddy can't drink," she explained.
Bell added that her daughters love the drink so much they've even 'ordered' it at restaurants, and she's even walked in on them drinking it during their online classes for school.
"They have 15-minute breaks where they're allowed to jump around and grab a snack and wiggle it out," Bell said. "And I walk in to check on them at 9:30 and both of them are drinking an O'Doul's on their Zooms!"
"They're both just sipping their Doulies. And I'm like, 'What must these other parents and teachers think of me?'" she exclaimed, saying she has to remind her herself not to care what other people think.
"If anything, it opens up the discussion for why Daddy has to drink non-alcoholic beer because some people lose their privileges with drinking. Drinking's not always safe."
Today is my husband's 16th sobriety birthday. My daughter woke him up with this sign, and a sketch of the one and only Ronald Weasley(absolutely random, and also perfect). Happy birthday Daxy. Thank you for dedicating your life to the hard and wonderful work of sobriety, so that we could share it with you. Xo K, L & D
