Paternal time spent caring for children alone is qualitatively different from time together mediated by the presence of the mother and may be particularly relevant to father-child relations. Many fathers spend minimal time alone with their children. Indeed, it is still commonly referred to as "babysitting". We explored the concept of Solo Care as a conceptually discrete dimension of father involvement. Fathers and mothers in families (n = 110) with children aged 3-12 years provided qualitative and quantitative data separately in a structured interview. Several variables were considered as potential correlates of Solo Care, with parental occupation and hours of work, perceived maternal support, perceived barriers and paternal efficacy and satisfaction proving significant. Themes describing fathering satisfaction included father-child bond, pleasure in watching children grow and father-child interaction. Important benefits of Solo Care were relationship-focused along with the opportunity to demonstrate equal competence and fathers' differences from mothers. (Contains 1 table.)
