Introduction: Patronage nurse care has an independent role in the health and well-being of mothers and newborns. After leaving the maternity hospital, the health care and upbringing of the mothers is carried out by a patronage nurse. One of her roles is to help mothers with the establishment and maintenance of breastfeeding, and help with the care for the newborn. Aim: The aim of the research is to examine the mother's experience of sufficient assistance of a patronage nurse in caring for a newborn and in establishing and maintaining breastfeeding. Methods: The research is a cross-sectional prospective study conducted through an online questionnaire in the Facebook group "Moms and pregnant women 2020/2021" in June 2021. The study involved the first 100 random adult mothers who voluntarily decided to complete the questionnaire after its public announcement, and who gave birth at least 6 weeks before accessing the study. Underage mothers and mothers who didn’t gave birth at least 6 weeks before accessing the study could not participate in the study. A validated Generic Short Patient Experiences Questionnaire (GS-PEQ) was used for the study. The questionnaire was translated into Croatian and minimally modified for research purposes. Results: The obtained results show that mothers are generally satisfied with the help received by the patronage nurse, although they are still more satisfied with the help received by the patronage nurse in caring for the newborn than with the help received in establishing and maintaining breastfeeding. Conclusion: Based on the obtained results, the hypothesis that mothers are more satisfied with the assistance provided by the patronage nurse in caring for the newborn than with the assistance received in establishing and maintaining breastfeeding was confirmed and areas where further improvements are possible were identified.
