Cynthia and Todd are having marital difficulties. Cynthia decides to have a baby, hoping parenthood will improve their relationship. What advice can you offer them?

Accepted Answer

Deciding to have a baby in hopes of improving a troubled relationship is a serious mistake. The most important preparation for parenthood takes place in the context of the parents' relationship. Expectant couples who are unhappy in their marriages and who have difficulty working out their differences continue to be distant, dissatisfied, and poor problem solvers after childbirth. In a distressed marriage, pregnancy adds to rather than lessens family conflict. Only when a couple's relationship is faring well and both partners want and plan for the baby, is the excitement of a first pregnancy likely to bring the husband and wife closer.
