This chapter focuses on father-child wellbeing arguing that fathers are emotionally transformed by having a child and that children have a beneficial influence on father’s health and positive engagement in work. Previous research described how involved fatherhood offers men the opportunity to resist practices of risk-taking, denial of treatment, expression of anger, which are harmful to their health. However, studies on the relationship between fathers and children often overlook the mutual beneficial effects that these family members have on each other. Based on findings from 47 qualitative interviews and 6 observations with Scottish and Romanian involved fathers and their children, I show how children were described by fathers as re-energizing them for work and helping them let go of negative health habits, such as smoking, drugs, and reckless driving. Fathers in turn, adopted a long-term perspective for their health and wellbeing brought on by planning for the future. Conclusively, children seem to play an important role in counteracting the toxic aspects of masculinity, as children were described as helping fathers shift emotionally from stoicism and control to increased nurturance and emotional openness, thereby affecting their wellbeing in positive ways.
