In the final decade of the 20th century, reproductive behaviour in the Czech Republic underwent significant changes, which were manifested in, among other things, a decline in the birth rate. Views on the ideal number of children in a family have, conversely, remained consistent in the population over time, and the ideal of the two-child model has been repeatedly identified in sociological studies over the long term. Given the currently very low fertility rate and the continued postponement of childbirth to a later age, it is important to ask whether the proclaimed aspirations for a two-child family will be fulfilled and whether the tendency will be for women to actually have a second child. This article focuses on values associated with children and especially selected factors connected with the decision to have a second child, including an evaluation of the factors that women take into consideration when deciding to have more children. The analysis is based on data from the survey Men and Women in the Czech Republic: Life Courses and Inter-generational Relationships (GGS: Generations and Gender Survey), the first wave of which was conducted in the Czech Republic in 2005, and for the analysis focusing on a second child in the family selected generations of women were chosen.
