In this study, we focused on the period before the transition of children from home to kindergarten life. We aimed to describe the consciousness of the parents of the children, who interacted with the children of the kindergarten into which they were planning to enroll, as part of a child rearing program (hereinafter referred to as “the program”). We also considered the effects of the program and the various considerations of implementing it. The parents were asked for their impressions of the program via a questionnaire, which was analyzed by Steps Coding and Theorization (SCAT). The results indicated that parents were able to confirm the validity of their choice of kindergarten by participating in this program. It also became clear that the parents were able to form and update their views on their own children’s development through comparison with the kindergarten children, and that these experiences were intertwined with their anxiety about their children’s current situation and their expectations of kindergarten life.
