Background: Breastfeeding is process by which human milk is fed to infant, may be from breast, or expressed by hand or pumped and fed to the infants. Breastfeeding is natural process that seems to have been adversely affected by the “modernization” of society. Several factors affect initiation, continuation, and cessation of breastfeeding among Indian women which includes various maternal factors, infant characteristics and socio-demographic factors. The aim of this study was to identify issue related to breastfeeding and study the various factors that affect the exclusive breastfeeding. Methods- cross-sectional observational study conducted at postnatal care ward of a tertiary care centre. Result: This study included 803 mothers and 811 neonates which were not admitted in neonatal ICU. Out of 811 neonates 577(71.15%) were exclusively breastfed while 234(28.85%) were not, from that 60.9% male neonates and 81.07% female neonates were exclusively breastfed. In twin pregnancy exclusive breastfed were 25% while in singleton pregnancy 72.08%. According to mode of delivery in vaginal delivery 86.20% and in caesarean 55.53% were exclusively breastfed. Around 71.48% term neonates were exclusively breastfed compared to 62.07% preterm neonates. Breast problems in mother that led to non-exclusive breastfeeding contributed around 18.38% while problems in neonates around 4.70%. Conclusion: Twin pregnancy and caesarean section delivery were associated with significant fall while there is no effect of gestational age of neonates, parity of mother, maternal education on rates of exclusive breastfeeding. So, we need to focus on a community based educational programme to promote antenatal counseling about benefits of early and exclusive breastfeeding.
