The aim of our investigation was to find out how do pre-school aged children felt themselves in kindergarten and what factors their well-being depended on. The survey was carried out in 1999 and 2000. A sample of 631 children aged 6-7 years was interviewed in 12 randomly selected kindergartens of Kaunas. The children were divided into two groups. The children who said that they liked to be in kindergarten more than at home belonged to the first group (n = 361 or 57.3%). They answered that they liked their group mates, like to speak with their teacher, to learn, to sing, to play quiet games, they heard good words about themselves in kindergarten more often. The children who enjoyed to be at home more than in kindergarten belonged to the second group (n = 269 or 42.7%). They said that they did not like to obey the tasks of their teacher, to sleep after dinner more often in comparison with the first group.
