Katie and Greg struggle to help the kids accept loss as a family friend suddenly passes away and as their pet pig, Hans Gruber, must be returned to his natural habitat.

Katie goes to great lengths to appease Principal Ablin in order to ensure Taylor graduates high school. Meanwhile, Greg finishes ghost writing the final chapter of Lonnie's book. And while Oliver is devastated to learn Cooper's family will be moving out of Westport, Anna-Kat tells Franklin she is ready to venture outside her comfort zone and plans to attend sleep-away camp during summer break.

With Anna-Kat and Franklin home with mono, Katie seizes the opportunity to use them as the backdrop for her mommy vlog. And when Taylor's first college paper comes back with an A, Greg questions her TA's intentions. Meanwhile, Cooper helps Oliver renovate the basement.

Katie tries to fit in with the other Westport moms in order to get Anna-Kat invited to a popular girl's birthday party. When Anna-Kat still isn't invited, Katie vents to Angela and Doris, and realizes her daughter doesn't need a bunch of friends, just a couple of close ones. Elsewhere, Greg tries to convince Taylor that she can't get by on her athletic ability alone, while Oliver complains about a flawed polo shirt that his mom bought at an outlet store.

Greg comes down with the flu and Katie battles exhaustion trying to take care of him and the kids. Her exhaustion leads to a confrontation with the school's overbearing school crossing guard.

Katie's holiday spirit, never great to begin with, is soured even further when Viv corners her into helping out with the school Christmas pageant. Greg, determined to teach Taylor and Oliver the true meaning of Christmas, takes them to a local nursing home to cheer up the residents, but things don't quite turn out the way he planned.

The Ottos face the prospect of leaving Westport when their house is put up for sale. No one wants to leave except Katie, who seems determined to move on despite some fun memories of her family's time there.

Katie's least favorite holiday is Valentine's Day, but her desire for a low-key approach is overridden by Greg's over-the-top romantic gestures.

Greg befriends fellow history buff Stan, but Katie is less than pleased, especially considering he is married to her nemesis, Chloe Brown Mueller.

Katie has been avoiding the mandatory volunteer hours at her kids’ schools all year.

But things soon get out of hand after her former frenemies plan a baby shower for her.

Greg plays dirty to convince Katie to let them keep Anna-Kat's beloved pet pig; Oliver and Viv compete for the attention of a new neighbor; Taylor considers leaving her boyfriend.

After feeling like their whole world and all of their conversations revolve around kids, Greg and Katie are ecstatic to meet new friends Zach and Courtney, a couple without children. Meanwhile, Anna-Kat coerces Taylor and Oliver into helping her with a storytelling project, which turns out to be a little more grisly than anticipated.

Katie and Greg dislike Taylor's new boyfriend, so they attempt to use reverse psychology to drive a wedge between them, which later backfires. After Spencer's over-the-top vision for Oliver's first date with a girl from his ballet class bombs, Greg helps Oliver make up for it with a romantic gesture.

The Otto children are beginning to experience struggles in their love lives after jumping into the dating world: Oliver is forced to choose between his girlfriend and his friend Cooper who come from two different worlds; Greg must play the “bad cop parent” to halt the PDA between Taylor and Trip; and Anna-Kat tries to make her relationship with Franklin official, without his consent.

With her new job taking up more of her time, Katie and Greg try to split up parenting duties. Katie over-involves herself in Taylor's social life by trying to keep some distance between Taylor and her boyfriend, Trip, to make sure Taylor is her own person aside from him. Meanwhile, Greg tries to convince Oliver to be honest after overhearing Oliver lie to his friends about his less-than-luxurious summer vacation.

Katie lands the perfect pawn to play on the insecurities of the Westport housewives when she convinces a hot young trophy wife named Harper to volunteer as room mom for Anna-Kat’s class, but she quickly shifts gears when Harper rejects Anna-Kat’s idea for movie night. Meanwhile, Greg enlists the help of the kids to get Katie’s mom, Kathryn, to take an interest in someone other than herself.

Katie strives to keep her long-separated parents apart when her father, Marty, arrives in time to surprise the Otto family for Christmas. Anna-Kat does her best to help Trip win Taylor back but has a hard time getting past a very persistent Pierce. Meanwhile, Oliver thinks no one will remember him as the mask-wearing villain in the school’s production of “The Nutcracker” but quickly takes center stage when a series of mishaps damages his costume.

Greg’s insistence on doing the family’s taxes prompts Katie to take matters into her own hands. Meanwhile, Oliver and Anna-Kat join forces in an attempt to win a popular radio contest; and when Taylor finally sees Pierce’s true colors, the family bands together to help her pull off an over-the-top apology for Trip.

Katie plans a “friend date” in hopes of reconnecting with Taylor and encourages Greg to attend self-help guru Johnny Diamond’s seminar with Oliver. Meanwhile, Anna-Kat takes extreme measures to secure her place as Katie’s favorite child.

After coming to terms with the fact that she must share her work bonus with Greg, Katie encourages him to live a little and the two decide to splurge on an overnight getaway.
