The objective of this paper is to understand the emotional development of baby cared for in two different contexts: nursery and at home. This research was carried out in Brazil. As recommended by the Bick method, weekly visits were performed at home and in the nursery, always accompanied by transcription and discussion of cases in the supervision group. In this study, a 9-month-old baby was observed for four months. The results point to the construction of the autonomy of the baby, stimulated or not by the caregivers. The concern with care was observed more intensely at home, where the mother had difficulties in dealing with the acquisition of the autonomy of the child. In the nursery, autonomy is stimulated from interaction activities with other children. It should be noted that a good environment, once provided through care, enables new experiences and contributes to the building of emotional development.
