With Maddie's baby on the way, David is concerned about there being so much to learn. Following Agnes' suggestion, he tries to enroll in a Lamaze class. When he is rejected, David tries to practice on Herbert. When that fails, he goes looking for an unwed mother. A woman comes to him and asks him to help her through the birth of her baby. So he does the class with her. When Maddie receives a package with childbirth books and later learns it came from David, she realizes that she wants to be home.
