Meanwhile, Anne receives unwelcome news, which leaves her grappling with a life-changing decision. And Frankie tries – and fails - to keep her postpartum depression from affecting her work.

Kate tries to juggle it all: motherhood, work, exercise, baby classes, date night… and packs it in to the point of nearly jeopardizing a performance review at work. Luckily for Kate her reputation precedes her – and she’s one of two candidates being considered for a promotion. Can Kate continue to pursue her career to the highest level? Meanwhile, Anne tries to reign in her sexually explicit nine-year-old daughter. And Jenny reluctantly returns to work where she reconnects with an old friend: her sex drive.

Kate has difficulty letting go and embracing a softer side; both at work and when she entrusts her dramatic mother with nanny duties. But Kate must call upon her “mama bear” instincts, when she is forced to help Frankie out of a dangerous situation. Meanwhile, Anne tries tough love with her wild child daughter, and Jenny attempts to attract the interest of her new manager, but fails — confusing him, and sending her further down a reckless road.

Eleanor quickly takes over babysitting duties; running Kate’s household and Charlie’s schedule her way. Now that Kate’s hired her, can she actually fire her own mother? Meanwhile, in an attempt to shut down her daughter’s wild nature, Anne hires a “mean nanny” who can keep Alice in line, but also threatens to keep Anne in line too.
