Meghan and Nick decide to celebrate their anniversary by spending a night away from their children.

Beth is accused of lying to the group, leading Stefanie and Leah to come to her defense. Meanwhile, therapist Jill helps Meghan with her daughter's potty-training woes; Leah hosts an etiquette party; and Jen goes on an online date.

Leah's party continues with rising drama. Meanwhile, Jen shows no mercy toward Beth at mommy group; Stefanie faces her fear of singing; Beth confronts her own fears; and Stefanie presides over a girls' night to heal the group's wounds.

Meghan invites a psychic over to prove to Nick that their fourth baby is written in the stars. With her love-life stalled, Jen contemplates having a baby on her own. Jill pays a visit to Leah’s house to assess whether Leah’s fears of turning into her mother with her own daughter Jade are true.

Will she come home with a new baby-daddy?
