The paper presents the results of the psychological research on interaction of mothers with preschool children with intellectual disabilities.

The basic idea of the scientific research is optimization of emotional interacting of mothers with preschool children who have intellectual disabilities by means of psychological training which is aimed at developing emotional-sensual, empathy-behavioural and cognitive-reflective components of parenthood. The data mentioned above describe the emotional side of mother’s interaction with the child as a disjunction, i.e. most of the mothers manifest low sensitivity to the condition and needs of the child, lack of understanding the causes of child behaviour, inability to empathize to the child when he/she is in a predicament. In order to improve mothers’ understanding of their own children, characteristics and regularities of child development, to enhance the ability to understand the experiences, states and interests of the child, to change attitudes of parents to the child and themselves a training program has been implemented. The results of the control phase of the experiment conducted show the positive effect of group work on peculiarities of parent-child emotional interaction. The number of mothers who are able to understand the reasons for the child’s moods, sympathize with child, set him/her calm attitude increased. Mothers’ impression that they are controlling the development of their child has appeared. Mothers were more likely to seek physical contact with a child. A larger number of mothers began to provide emotional support to their children and to take into account the mood and interests of the child in leisure activities planning.
