Orgain, Diana. The Maternal Instincts Mysteries: Bundle of Trouble, Motherhood is Murder and Formula for Murder.
Each of the three books in the series is juxtaposed with a month in Laurie's development. Kate is a charming and determined heroine, who truly believes that both she and her daughter will suffer if she has to return to her office job.
Page, Katherine Hall. The Faith Fairchild Mysteries.
Faith has trouble settling into the small community, as she just doesn't fit into the villagers' idea of what a minister's wife should be. Her discovery of a young woman's body, stabbed with a kitchen knife, in the church's belfry does not aid this perception, especially when the bored Faith, who has a very well-developed sense of curiosity, decides to find out what happened.
By the end of book three, The Body in the Bouillon, Faith is making arrangements to take over a local catering company, and also discovers that she's expecting. Daughter Amy first appears in book five, The Body in the Cast.

During the course of the series, Juliet has another child, the family moves into a bigger house, and she hangs out a shingle as a private investigator with former cop Al Hockey. Juliet is a wonderful character who struggles with her weight, and tries to stay sane while being a stay-at-home mom.
