Background: Postpartum treatment is an integral part of being a healthy mother and baby. However, neglecting the quality of care during this period can lead to maternal illness or infant death. Complications can be avoided if postpartum care is used properly. The study identified postpartum care practices among mothers of newborns in selected areas of the hilly region of Bangladesh. Method: A cross-sectional study was performed on 556 postpartum mothers. A semi-structured questionnaire was used to gather relevant information through a convenient sampling method for study subject in a hilly region of Bangladesh. Result: A total of 36.2% of mothers received PNC services only. In bivariate analyses, many variables showed strong associations; however, in the multinomial logistic regression study, only a few variables remained significant for post-natal care groups. Mothers with little or little education (1-5 years of schooling) had a significantly lower probability of receiving postnatal care, whereas higher education seems to have a strong and significant connection with the postnatal care practices in the hilly areas of Bangladesh. Women who watched TV had a significantly higher likelihood. Socioeconomic status had a strong relationship with receiving postnatal care services. Cultural beliefs and local perspectives on neonatal care practices predominate there. The study also found that PNC has a significant relationship with ANC. Conclusion: Government and community leaders should work together to strengthen maternal health care and raise health awareness considering their unique way of life and geographical location.
