Season 3

After spending years as a full-time mom, Katie goes back to work as a party planner, which brings new challenges of balancing home and work life into the mix.

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.

When Katie's mom, Kathryn, comes to town, Katie and Kathryn encourage the kids to make less than favorable decisions: Oliver cheats in shop class and Katie helps him try to get out of it, while Kathryn reassures Taylor that she doesn't need to go to college.

Anna-Kat runs for the Green Chair position in the school election against Chloe Brown Mueller's daughter, which results in Katie and Chloe turning their kids' election into a feud of their own. Meanwhile, Greg becomes concerned that Taylor's new friend Pierce is trying to steal her away from Trip, causing Greg to intervene and scheme to prevent it.

When Taylor decides she wants to go to a Halloween party, Greg and Katie disagree on whether or not Taylor can be trusted. Oliver and Cooper anxiously try to prepare for playing a game of Seven Minutes in Heaven with their dates at a separate Halloween event. A pregnant Viv follows Katie around, trying to get help preparing for her baby before it arrives.

After the previous “fattest housewife” in Westport gets plastic surgery to lose weight, Chloe Brown Mueller rubs it in Katie’s face that Katie has now assumed that title. In order to get revenge on Chloe, Katie goes through great lengths to dig up bad photos of Chloe from high school.

After discovering that the four digit pin code the Otto family uses for everything spells out Greg’s ex-girlfriend’s name, Katie gets upset and retaliates by dragging out old gifts from past boyfriends. Meanwhile, the kids’ current love lives take a hit as Taylor and Trip argue over her relationship with Pierce; and Oliver and Gina’s relationship goes south when they both apply for a ballet scholarship that only one of them gets.

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.

As Oliver and Taylor stumble through their love lives, Katie begins to miss the spontaneity and unpredictability of being young and in love. Meanwhile, Kathryn’s plan to soothe Oliver’s heartbreak backfires when she tracks down an old boyfriend, Dan, and he is not as she remembers. At the same time, Anna-Kat makes strides at school when Franklin is stuck at home with the chickenpox, forcing her to make a new friend.

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. Meanwhile, Oliver's attempt at a rebellious streak ends in disaster; and after letting Anna-Kat down, Taylor comes to the realization that she needs to step up and be a better big sister.

Viv asks Katie to take Violet for the night so she and Alan can discuss reconciling but is caught off guard when Greg is hit with a bout of baby fever. Meanwhile, Taylor tricks Oliver into helping her when Luther eats an expensive pair of earrings.

While Greg enlists Oliver and Anna-Kat’s help to drum up new recruits for the Westport Historical Guild, Katie does her best to support Taylor’s dreams of becoming the next American Idol.

Katie feels left out and slightly jealous when Greg becomes fast friends with the newest member of the Westport Historical Guild. Meanwhile, Oliver fears Cooper is ditching him when he sees on social media that Cooper lied about his weekend plans.

When Katie forgets Greg’s birthday, she attempts to make up for it by pulling together a last-minute dinner party; but when the evening falls flat, Katie gets caught up in a series of lies, leading her friends to believe that she and Greg are in marriage counseling.

In order to avoid buying Anna-Kat a cellphone, Katie makes a pact with the girls that she and Taylor can go an entire day without using their phones. Meanwhile, disappointed with Greg’s advice, Oliver seeks the guidance of an old friend.

When Katie gets sick, Greg enlists Kathryn's help in taking care of the kids, but Kathryn leaves the kids to fend for themselves while she entertains an old high school boyfriend. Meanwhile, Taylor gets a taste of her own medicine when she tries to help an unruly Katie.

Fearing she’s spending too much time at the office and away from the family, Katie volunteers to chaperone Anna-Kat’s school field trip to make up for lost time. Meanwhile, Greg takes a creative approach to parenting when he catches Taylor and Oliver in a lie.

Much to Katie’s dismay, Anna-Kat becomes best friends with Chloe Brown Mueller’s daughter, Penny. When Katie takes extreme measures to avoid Chloe and keep the girls apart, Anna-Kat and Penny are forced to take matters into their own hands. Meanwhile, Greg encourages Oliver to be honest with his girlfriend and not hide his passion for ballet.

With the kids away at the school dance, Katie and Greg look forward to a romantic evening alone; but Anna-Kat is crushed when the boy she likes doesn’t ask her to the dance, and Oliver begins to panic when the town psychic’s predictions begin to come true.

Frustrated by the lack of appreciation for all she does, Katie decides to go “full Westport” and leaves the family to fend for themselves. Katie’s plan quickly backfires when the kids seem to be doing just fine, leaving Greg to suffer the brunt of her absence.
