According to a heartfelt post shared by Bell, Shepard awoke to a sign made by 7-year-old daughter Lincoln reading, “Happy Sobriety Birthday Dady.” The young artist also drew and attached a picture of “Harry Potter” actor Ron Weasley, which Bell called “absolutely random, and also perfect.”

“Happy birthday Daxy,” the proud wife continued. “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.”

Shepard, 45, and Bell, 40, also share 5-year-old daughter Delta.

Last fall, the “Armchair Expert” podcast host spoke to The Huffington Post about sober parenting, revealing his occasional jealousy of buddies who can indulge themselves, especially while on vacation.

“We vacation almost exclusively with three other families who all have kids, and certainly at night, I’m super jealous of them because I’m like, f–k yeah I would love to drink something that turned down the volume of everyone in this house,” Shepard said. “So I’m a little bit jealous in the evenings.”

Come daylight, however, things always seem to balance out.

“At 6:45 when we’re all up, I’m like, ‘Oh I’m crushing right now,’” he added. “I feel great. And they’re miserable. And those voices are three times as loud with a hangover. So I just have to focus on when the win is, which is always the morning.”
