Adolescent fatherhood is often associated with negative stereotyping and deficiencies in the adolescent's situation or characteristics, which effect his investment in child rearing. Developmentally, adolescence is a time when parenthood is not conventional practice nor a well-accepted norm. Understanding how adolescent fathers make sense of transitioning to parenthood allows us to re-think our public representations of young fatherhood. This article seeks to examine the ways that adolescent fathers reconstruct their identity in the midst of becoming a parent. Social constructionism offers a critical approach to the consideration of this transition process. A discursive analysis, based on interview transcripts, looks at the talk of adolescent fathers, and suggests they have a significant investment in their changing identity. Through their language, they actively engage in a process of change that illustrates management of new responsibilities, which arguably develops an attitude of mastery in their lives, instead of ineffectiveness as suggested by stereotyping.
