The present work was carried out by interviewing mothers with her infants and collecting information about type of feeding. sex, age. order of the infant in the family. birth weight and infection of diseases (diarrhea, chest allergy and gastroenteritis allergy). Anthropometric measurements of the infants (weight. length and head circumference along 3 months) were also determined. Results indicated that the percent of first order for the infant of bottle feeding in urban was 64.5%, which was higher than the percent of the first order for the infant of breast feeding (34.3%). Type of feeding affected the infection of diseases of the infants The breast feeding infants had the lowest infection of disease of diarrhea, chest allergy and gastroenteritis allergy than infants of bottle feeding. Infant birth weight of the infant was significantly differed between infants of breast and bottle feeding in urban in spite of in rural areas. The normal growth rate of weight for both boys and girls infants were better in breast feeding infants than infants of bottle feeding by 50 percentiles. Also, the normal growth rate of length for boys and girls infants were better in breast feeding than bottle feeding by 50 percentiles. These were insignificant difference, among lengths of infant boys, while there were significant differences among lengths of infant girls, Regarding the head circumferences of the infants. it could be seen that the normal growth of head circumferences for boys infants of breast feeding were more than infants of bottle feeding in 50 percentiles. while, there were insignificant differences in girls.
