The aim of this study was to determine the effectiveness of follow-up care and health counselling provided by midwives and nurses in maternal-infant attachment level and relationships between sociodemographic factors. The study was designed as a quasi-experimental pattern with a control group on pretest-posttest. The sample size was determined using a power analysis and a total of 90 people were included in the study. The study demonstrated that the mean PAI score was high both in experimental and control groups and there was no difference between the groups (p > 0.05). In both groups, the mean MAI score was above the average scale score, but it was significantly higher in the group receiving health counselling and follow-up care compared to the score of the other group (p < 0.05). The study demonstrated that health counselling and follow-up care contributed significantly to the mother-infant attachment.
