AbstractFathering activities of 16 fathers of firstborns were surveyed via questionnaire to assess their involvement in physical caretaking, affective interaction and support of mother through participation in household tasks. Results indicated that student fathers who had previous infant care experience, whose infants were unplanned and whose wives were either employed or attending school spent the most time interacting with their infants. Other variables explored which had little effect on father's interaction time included: formal education, attendance at prenatal clases, infant's sex and method of feeding, family isolation. Fathers spent more time in affective interaction than in physical caretaking. Time spent by fathers in affective interaction was nearly equal to that of mothers, while time spent in physical caretaking was much greater for mothers.
