This thesis work is based on the assumption that fatherhood has undergone major changes in the last three decades. More and more appears the so-called new fatherhood which replaces the traditional pattern of fatherhood. By applying a qualitative analysis of the life course of fathers, the goal was to contribute to the understanding of practice and attitudes about transitions to marriage, transitions to parenthood and involvement in upbringing. In the research, semi-structured interviews were conducted, and the selection of participants was carried out partly through acquaintances, and partly using the snowball method. Although the participants in the oldest age category have a traditional pattern of fatherhood, the other participants show a shift in parenting. The pattern of new fatherhood is present in the participants of the youngest age category. The participants' views on the division of household chores, as well as child care point to the dominance of an egalitarian family, except for the participants in the oldest age category.
