The knowledge, attitudes and intentions of health professionals about breastfeeding are important not only because of their personal decisions but also for their professional approach to the future or young parents regarding initiation and maintenance of breastfeeding. This study aimed to determine intentions, attitudes and knowledge about breastfeeding among students of nursing at the University of Bjelovar. Data were collected by a validated questionnaire. Differences in outcomes by study type (full-time and part-time students and students motivated for additional breastfeeding education) and gender were analysed by t-test and MannWhitney test. The worst results on the BIAKQ questionnaire on the particles of intent were achieved by students in terms of breastfeeding after the age of two and breastfeeding in the workplace, on the particles of attitudes regarding father’s help to the mothers who are breastfeeding in their workplace, breastfeeding for more than two years, equivalent food and breast milk, and legal regulations on the right to breastfeed in a public place. The worst result on the knowledge particles was achieved in terms of nutrition and quality of substitute food in relation to breast milk. The results of the students did not differ statistically significantly according to the way of studying or gender, the closest significance was the difference in the attitudes of female and male respondents (p=0.06). In conclusion, the knowledge of students is insufficient, and a much bigger problem is their attitudes and intentions that deviate from the instructions of the profession. This leads to the realization of the necessity of structured continuous education on breastfeeding in order to update knowledge about the importance of breastfeeding and breast milk with recent knowledge and practice individual and group techniques aimed at correcting unhealthy and undesirable intentions and attitudes about breastfeeding. The results of such education cannot be measured by school grades (because they do not respect intentions and attitudes), but by specialized validated questionnaires
