The aim of this article is to describe the experiences of children whose mothers suffer from postpartum depression. Population studies show that although depression affects about 6% of people in the population, pre-natal and post-natal depression affects 12-20% of women. This means that, at present, in Poland depression and subdepression is experienced by about 48 to over 73 thousand women. Studies show that maternal depression has long-term consequences for cognitive and emotional development, both in infants and pre-school children. In addition, studies show that the mothers' own treatment, both psychotherapeutic and/or pharmacological, while contributing to the reduction of depressive symptoms, is not sufficient to improve the relationship between mother and child. The article presents a review of research of effective interventions with depressed mothers and their infants. It also presents a description of therapeutic work with children whose mothers were depressed in the first 3 years after childbirth.
