Researchers have a limited understanding of how men become ready for fatherhood, especially among young, low-income men in the transition to fatherhood. The present study draws a diverse sample (n = 53) enrolled in fatherhood programs in Midwestern cities. Life history interviews were conducted with the participants and grounded theory was employed to identify common themes among the narratives. Four cognitive dimensions of fatherhood readiness were identified by the current investigation: presumptive paternity and acknowledged paternity that one is a father, fatherhood vision, maturity, and men's perceptions of their provisional capacity. These contributed to the construction of narratives that describe fatherhood--trial readiness and decided readiness. Implications for social policies and programming are discussed.
