Aim of the study:
The aim of this study is to asses the relationship between postpartum depression and perceived social support, newborn temperament, and selected sociodemographic variables.

Subject or material and methods:
The sample consisted of 145 mothers, with an average age of 27, mostly married. The following instruments were used in the research: Questionnaire on sociodemographic characteristics, Neonatal temperament scale, Edinburgh scale of postpartum depression - EPDS and Scale of perceived social support.

Results:
The results showed that reduced social support from partners, friends, and family, difficult newborn temperament, and low socioeconomic status correlated with postpartum depression.

Discussion:
The practical implications of the research are reflected in the understanding of social support as a significant predictor of depression in the postpartum period and the implementation of the social component in the system of support and assistance to pregnant women and mothers.

Conclusions:
Recognizing the factors that cause mood disorders after childbirth is an important part of the diagnosis and prevention of postpartum depression. Postpartum depression is a non-psychotic postpartum mood disorder that can last up to 12 months postpartum. The etiological disorder is still not differentiated because it is differentiated through a bio-psycho-social basis.
