At Chuy’s insistence, Bill and Jo finally enroll Lulu in preschool only to discover she is a biter. While they navigate incident reports and overprotective parents, Sandy explores their family history with an ancestry DNA kit.

Bill and Jo reluctantly ask Sandy to babysit after Chuy and Brie convince them to join their weekly date night. And while Bill and Jo discover they’re a bit rusty at romance, Sandy discovers she’s a bit rusty at parenting.

In an attempt to get Emily interested in something other than her tablet, Bill and Jo enroll her in her uncle Chuy's soccer clinic. Sandy's infamous gift-giving habit gets out of hand.

Bill and Jo take their niece Marta in after she clashes with her father, while Bill regrets playing matchmaker when he gets wind of Dave’s plans to propose to Sandy.

On their 10-year anniversary, Bill and Jo decide to renew their vows, but their overzealous extended family and an approaching snowstorm threaten to ruin the event.
