In our research, we tried to find a quantitative answer to the question about the role of society and family in the individual development. As part of the review, the prevailing views on this matter have been singled out. The question was also narrowed down to the relationship of family policy and child development using the methodology of grounded theory. We have formulated the hypothesis that state and society intervention into intrafamily relations can be monitored by the percentage of children's time spent in the family and outside the family, as well as by the government incentives offered to families with children. Based on the literature review, it was hypothesized that society would not benefit from large-scale public intervention into the affairs of families with young children. The hypothesis was later confirmed however, it remains implicit. At the same time, the effect becomes more obvious in the historical perspective. The analysis of the family policies of developed countries at the end of the last century showed that the scale of public intervention into family affairs was smaller and the effect was positive. The scale is increasing now and the positive effect of public intervention into intrafamily relationships is being lost.
