The research was conducted between 2010–2012. The participant group consisted of 972 children aged between 1 to 41 months and their parents of different socioeconomic status, inhabiting different parts of Poland. The research was carried out in their home space – the most natural environment for children. The IT-HOME/PL Inventory, a Polish adaptation of the American IT HOME Inventory (Infant/Todler Home Observation for Measurement of the Environment) by Betty M. Caldwell and Robert H. Bradley, was used. The results show that the social development environment differs visibly depending on the age of a child, which is coherent with the characteristics of the developmental phases presented in various concepts of human development. The first developmental period – infancy – finishes at the age of about one year, followed by early childhood in the second and third year of age. Each of these periods is characterized by different developmental needs of a small child requiring different organization of the developmental environment. However, according to the results achieved, the sex of the child is not a diversifying factor for the quality of social circles in which the child  develops in the period of early childhood.
