The rates of breast-feeding in the first 4 months in 3 areas (urban: Hanoi, rural: Hung Yen, and mountain: Bac Kan) were very low (30%). There are many reasons influencing these rate such as the mother did not have enough breast-milk, mother got disease, preferance of bottle-feeding..., accessing media information of breast-feeding and alternative foods decreased from urban to rural and mountain. In order to lower these rates, it is necessary to propagandize and update information of breast-feeding, especially for mothers in rural and mountain areas
