In an effort to get Anna-Kat invited to a popular girl's birthday party, Katie dresses up like other Westport mums and spends time at the yoga studio.

When Oliver reveals that he's so embarrassed by his parent's modest house that he'd rather not have a birthday party at all, Katie decides to teach him a lesson by throwing him a surprise party at home with all of his wealthy friends.

Katie's efforts to get more time for herself backfire; Oliver proves to Katie that his passion for ballet is genuine; Taylor and Greg disagree over whether or not she needs to go to college.

Although Katie receives a lot of pressure about the spring gala, she insists on doing it her own way; Greg throws a barbecue.

Katie's scheme to get out of mandatory volunteer hours and the kids' school by pretending to be pregnant gets out of hand when the other mums plan a baby shower for her.

When Doris insists that Katie attend the charity polo match she's organising, Katie invites her best friend from college.
