This research addresses caregivers and infants in the infant class in the day-care centre. It focuses on an intervention programme with the goal of getting to know the attitudes of caregivers and examining their influence on infants. In the programme, the caregivers will be given the possibility of sharing with peers and of learning contemporary knowledge. The chosen research approach is the mixed methods approach, in which both quantitative and qualitative strategies are used. The sample included 23 caregivers of the 'Smart Start' Chain. All the participants filled out questionnaires before and after the intervention programme. Some were interviewed, and the data of the intervention programme itself were collected and analysed. The research presents the change caregivers experienced. The intervention programme can constitute a basis for an instruction programme that will increase the quality of the solutions provided for caregivers and thus for infants under their care.
