The mothers who had a higher income and a higher academic career tended to prefer the bottle feeding to the other. And first birth order made them select the breast feeding rather than the other. Generally mothers knew the information about infant nutrition very well (91.0%), but their knowledge actually did not work. The sources of mother`s information on the infant nutrition were the books of rearing infants and magazine. But there were some discrepancies between the actual and needed source of information; i.e. mothers wanted to acquire their information from mass communication.
