This study is to understand if the introduction of a newborn baby will cause any adaptation and change in couple relationship and their whole family. To achieve this goal, the researcher used qualitatively deep interviews with eight new parents whose first child was around one year old and who were yet to conceive the second child. Following are the significant findings: 1. Life focus reshuffle is obvious. From the beginning of the pregnancy, the mother-to-be is the focus the family. After delivery, taking care of the new mother and the newborn baby is the main point of family life during the first post-natal month. After that, family life revolves around baby caring. All these would influence each member of the family to a certain degree, and new role behavior emerges. 2. The newborn baby influences the family in three ways, including the inner change of the new parents, the change between the couple, and the change among generation relationship. 3. On the inner change of the new parents, the newborn will mainly affect its parents’ career planning and their jobs, particularly the mother’s. The other influences include stronger sense of responsibility, more gratefulness, concrete objectives, self-demanding, and setting good examples. 4. Between the couple, the involvement of the newborn baby also affects in three ways, including changes in family life focus, the couple’s interactive model, and the affection between the couple. Life focus turns around the child and the couple has to adapt themselves to house chores sharing and to the way they interact. During the process of transforming, the interviewees feel the mutual support between spouses is the most important. Most of the interviewees are grateful to the arduousness and support of their better half. 5. Though the support and assistance from the new grandparents now are not so much as those years ago, they still help a lot to relieve the burden of the new parents, and contribute to the better family interaction.
