The family is the smallest unit of society. According to the classical, ideal interpretati on of family it consists of a father, a mother and at least of one child. According to the traditi onal model the father id the breadwinner, he supports the family; whereas the mother runs the household, she brings up the children; the children’s task is studying, perhaps helping the mother with running the household. On hearing the word ‘family’ ‘unity’ and ‘harmony’ come to mind, whereas each family member has diff erent personaliti es with more or less sameness. They try to solve the problems arising in the family together, but every family member can have their own problems. Family members infl uence one another’s decisions, which can involve economic decisions, too. The number of children exercises the greatest infl uence on economic decisions. In our fast, modern, consumer society children wield the most signifi cant purchasing power. Their needs usually defi ne the family’s purchasing habits. Today children demonstrate their own needs in the market.
