Introduction: Breastfeeding is a natural way of feeding the infant, in which the mother provides the infant not only with nutrients, but also with a sense of protection and bonding, as well as the emotional support necessary for normal growth and development. Although breastfeeding is considered an instinctive skill, many mothers experience difficulties in the first hours and days after birth, which can be overcomed with good support and advice from health care professionals (midwives, health visitors, lactation consultants - IBCLC consultants and peer support counsellors). Aim: The research objectives included investigating the most common reasons for discontinuation of breastfeeding of the last child among respondents, the duration of breastfeeding of the last child, the correlation between the duration of breastfeeding and the level of education, the source of support and help during breastfeeding, and the influence of respondents' satisfaction with family and social support on the duration of breastfeeding. Methods and Subjects: Data for the research were collected using an online questionnaire posted on the social media network of a group that addresses breastfeeding issues. 42 respondents were included in the research. Findings: The data obtained from this research showed that the main reason for discontinuation of breastfeeding among respondents was readiness to stop breastfeeding; respondents breastfed their last child for more than one year, and their husband/partner provided the most support during breastfeeding. The data obtained show that there is no statistical relationship between the duration of breastfeeding and the respondents' level of education, and the respondents' satisfaction with family support. Conclusion: The hypotheses of this research were not confirmed and the results of this research are in contrast with other research on the same or similar topic. Respondents were significantly more educated and supported by trained lactation consultants, which highlights the importance of education and professional support on breastfeeding success and duration.
