The results of the present study showed that fear of Covid-19 was not a significant predictor of BSE, while spouse postpartum social support and having the intention of breastfeeding were positively associated with BSE. Depression and simultaneous use of formula in feeding the infant was negatively associated with BSE during Covid-19. Overall, breastfeeding can be encouraged through counseling to improve receiving spousal support, increasing breastfeeding intent, and reducing depression.
